         Introduction

         We begin making a sketch of how it was born, expanded and become to its declivity astrological science, resorting to historians and trustworthy sources; between the reasons so that Astrology provokes so many mistrusts and smiles of self indulgence they are the ignorance and interested opinions existing on the subject, that in some cases remain by pure inertia. 

         The science of the judgments of stars - therefore they call some works dedicated to it - has been remarkable and substantial part in the development of the human knowledge; so, it was considered and always enjoyed of great prestige. It was not until centuries XVII and XVIII when it was evacuated of European universities. 

         As all human knowledge has undergone cyclical happening of History, with its bumps, but in the periods of splendour of the cultures that developed, Astrology were cultivated by the intellectual elites of those times. From Astrology, we cannot forget it, was born Astronomy as we know it in the present time, although we do not have to forget that, in general terms, as much Astrology as Astronomy were both synonymous terms until century XVII.  It is not a hastic affirmation ours, historians confirm it and we can verify themselves in the libraries (1)   

         Astrology basically deals with the influences of the stars on the Earth.  The “natural " part, dedicated to the study of chronology, measurement of the time, annual climatic cycle, etc., has never been prohibited;  Saint Isidore of Seville, in his Etimologias, finds it totally legitimate and worthy of study.  However, the one that deals with the destiny of people, kings and nations, has always got in troubles, and that for diverse reasons. 

         To make predictions for a governor has always been jeopardize; in other cases the problem of fate has always arisen questions of philosophical, theological or religious type. The Cordovan Jew Maimonides, that studied it and had a deep knowledge about the subject, wrote against this type of  " divinatory" Astrology in its work On Astrology.  Letter to the Jews of Montpellier (2)   exclusively dedicated to discredit it. Geminus, by beginning of our Era, already claims in its Introduction to the phenomena (3)   against those who attribute to stars and not to the effect of the Sun the algid periods of heat and cold that takes place in the annual cycle (from that false belief comes the dog days, when the heat of the summer at that moments was associated to simultaneously risings of the Sun and the Greater Dog). 

         In any case, if we want to approach to the problem, the best thing will be to resort to the written sources and verifiable facts, and not to mere hypotheses or prejudices. Because these last ones, as Voltaire said, are the reasons of stupids. 

 

         Paleolithic astrology

         It can seem surprising to speak of science of stars in the Paleolithic period (-35,000 to -10,000 approximately); but, according to the archaeological and historical investigations and findings are advancing, the knowledge of the humanity in those times surprise enormously those who, by ignorance or simpleness had to the men of that time by gross and ignorants. 

         We must not talk of paleolithic astronomical science in the sense that this word has now, although there is no doubt that they were times in which the Moon constituted the great chronometer of the humanity (lunar chronology). The paleolithic tribes, with a low density of population, were nomadic, so the only valid temporary reference for them was the Moon, as much to choose the suitable moments of hunting and fishes (here the light of our satellite is important), as fixing the celebrations, encounter with other tribes for interchanges, and, of course, to compute the time. 

         The lunar chronology is based on the cycle of 27.5 days (approximately 28) that takes the Moon in crossing the stellar belt that serves as reference to determine its revolution;  since every night is visible on a star group and to the next one it is had displaced towards others located more to the left of the observer, there is no doubt that the nightly observation of this path originated the first Zodiac of stellar reference, which later was known as “lunar Mansions" or " Dwellings " in Europe (Middle Ages), introduced by the Arabs, who took it from Persians, Indians and also probably of China, a nation with very old astronomical calculations.

         The Zodiac is a Greek term that means " animal way ";  the Greek Zodiac, that still we use today, has some human figures (Gemini, Virgo and Aquarius). The Chinese Zodiac, however, only consists of 12 animals, so we might suppose it is previous, and possibly it has its origin in the Paleolithic (importance of hunting in the economy of that time). 

         Without any doubt the system of " lunar dwellings ", that are 28, is older  (28 are the nights of the lunar month in which our satellite is visible on the fixed star background).  Considering that the day of the New Moon our satellite is not visible in the sky, we have a total cycle of 29 days (the cycle of phases consists very approximately of 29.5 days). 

         In the famous cave of Altamira (Cantabria, Spain) they are counted up to 27, 28 or 29 bisons, that are painted on the ceiling and we need to watch upwards as in the cupola of a church (where also we see represented suns, moons and stars next to angels and saints, God and the Virgin Maria, etc.).  Bisons are strongly coloured in red and ocher, others do not have colour (perhaps they have lost it), adding a total of 21 animals; the others have black colour.  All of them do not present the same size; there is one greater than the rest, perhaps symbolized the Full Moon. If such interpretation is suitable, the black, dark and small would be representative of the days previous and followings to the New Moon, when our satellite is scarcely visible. 

         The interested reader can find published on this exciting subject the doctoral thesis of Luz Antequera in Hispanic Arqueoastronomy.  Astronomical practices in Prehistory of the Iberian Peninsula and the Archipelagoes Balearic and Canary. Altamira .  Astronomy, magic and religion in the Paleolithic.

         This author interprets the great bull of the cave of Lascaux (Dordogne, France) as the constellation of Taurus;  we can see a set of points in the same position that the Pleiades on the sky. If such interpretation is correct, we would have to suppose that, in the days of lunar chronology, it would be the time at which the first New Moon of the year (winter solstice) took place next to this stellar group.  In comparison of cycles, the winter (minimum solar illumination) is equivalent to the New Moon. 

         The fact that reinforces this idea is that in classic Egypt the Sirius star (Greater Dog) constituted the " home of the Moon ", when at the present, during the New Moon of winter solstice, our satellite is very far from that star, the main one of the sky. Made the calculations (precession of the equinoxes), the New Moon near the winter solstice took place next to Sirius in -11.500, approximately the date of Altamira (4)   

         There is no doubt that the alternation between day/night, activity/rest, ascending phase of the Sun/ descendent phase, added to the cycle of lunar phases, very early instilled in the humanity the notion of duality and cyclical nature of most of observable natural phenomena. The Paleolithic was a long time dominated by the lunar chronology, so the importance of the feminine divinity and associated ctonics cults.  The reckoning of the month began by the appearance of the New Moon (in Greek “neomenia”, literally " new month"), as we see at the present between Muslims and Jews.  The caves dedicated to observation and lunar cults that still last have to be oriented therefore towards the West, that is by where every month “is born  the Moon”.  Therefore, the day begins for the Jews (lunar chronology) at sunset (also it did in many places of Europe during the Middle Ages). The rosary is said at first time of the night (the Virgin Maria, Christian continuator of the lunar cults). 

         We can see lunar calculations in the " marks of hunting of Marshack ", some bones with groups of 7 notches (lunar phases);  in the “Venus of Laussel” we can see a horn (Moon) with 13 incisions, and in the rattlesnake of the Aztecs, 13 rings in the tail, etc. Here we are represented the 13 annual lunations (in fact 12 and a part, equivalent to an average of 354 days and fraction). 

         But the long paleolithic period finished with the climatic catastrophe of -10.000; Europe melted, and great cataclysms and alterations of the atmospheric circulation began to dry the Sahara . The transition began towards the Neolithic period, and with it came the solar chronology. 

 

         Birth as science in the Fertile Crescent

         With the arrival of Neolithic the populations became sedentary, and pasturing and agriculture were necessary for subsistence.  Such activities require the consideration of a solar calendar to guide themselves in the date of sowings, agricultural tasks, times of beginning and end of trashumance, etc.  In order to elaborate a chronology we can take every day as reference the points of sunrise and sunset for populations of fixed residence (peaks and crests of the mountainous horizon, etc.), because such points describe an annual oscillation.  The end points determine the solstices of winter and summer; both equinoxes can be known easily with approach, observing the shadow of a vertical stick at sunrise and sunset, because both form an air line those days (the rest of the year gives it irregular).  Months will be continued calculating by the Moon, at least until beginnings of ours Era.

         As much the nomadic populations as the sedentary ones can guide themselves in the annual time by another clock, the one of the risings and settings of stars at dusk or at dawn;  note that here also the horizon is taken as reference, very import in Astrology.  “To get orientated” comes from " Orient” (the East), " to look for the East ", which is in agreement with the main point of a horoscope, that is, the Ascendent (intersection of the Ecliptic or “way of the Sun” with the Eastern horizon).  Note also that horoscope, term of Greek origin, means " to calculate or to analyze the hour ". 

         The calendar of risings and settings of stars has been the third great clock of the humanity for guide itself in the annual time, and also in navigation by sea, all time and place. Today, in the big cities, scarcely can be contemplated the sky by night, and even in the country observation is difficult because of luminous contamination. Here we are the cause that citizens are aliens to the sky and absolutely unconscious of stellar influences.  Astrology could never arise from urban societies as ours; however, observation of stars in the country or cities without hardly nocturnal illumination, allowed to the populations of Antiquity a generalized knowledge of the sky, stimulating in them the feeling and the sensation to live united to the movement and evolution of cosmic cycles. 

         The first stars that appear by the Eastern horizon or disappear by the western one, at dusk and dawn, are a good reference to guide people in the annual time;  watching the sky at a determined moment we can realize that it turns a degree towards the West every day, so that some stars go appearing and others disappearing day after day.  The one that appeared today it will disappear after six months exactly and vice versa; some appear with the warmest days, others with coldest, some other with the arrival of rains, periods of winds or calm, others with the time of fervour of certain animals or childbirth, with the wheat harvest or the vintage, etc.

         From those experiences arose the feeling that the sky influences the terrestrial events and human happening (astrological thought).                  

         The transition to the Neolithic forced to a greater observation of the sky, the Sun and the Moon, as well as of a fixed horizon.  When the first urban sprawls in Mesopotamia arose, next to the great rivers (Eufrates and Tigris ), this stellar knowledge was systematized.  The phonetic writing was also born there, and the system of place value notation of base 12, at Sumerian epoch, (ca. -2900). Thus the first astronomical observations we know were registered (Enuma Anu Enlil), coming from the kassite period (ca. -1600 ).  

         By 1100 B.C. we have star lists called " of astrolabes ", in fact a calendar of risings and settings of stars, containing the " Way of the Moon ", positions of the Sun with respect to the cardinal points throughout the year, movements of planets and their cycles, weather forecasts, etc. 

         The so called at present " theorem of Pithagore " is not Greek, but mesopotamic, and the same occurs with the metonic cycle (repetition of the phases of the Moon the same date after 19 years), that takes the name of Greek astronomer Meton but it is well established that was determined before by Babylonian priests.  Religion and astronomy went united side by side in that historical period, for that reason the observations and conjectures of mathematical and scientific type were carried out in well structured sacerdotal schools. 

         We know planetary predictions from eclipses, conjunctions for the kings (omens).  For example, Tablet 63, that contains a complete list of observations of heliacal risings and settings of Venus during 21 successive years, with auguries, begin as it follows: 

         If 15 Sabatu Venus disappears by the west, remaining invisible 3 days, and 18 Sabatu it appears by the east, catastrophes for the kings;  Adad will bring rains, Ea underground waters;  the king will send salutings to the king. (5)   

         At that time stars were considered as Gods, and, in fact, Astronomy was used to interpret the divine will; in the poem  Enuma Anu Elish it is told that Gods, after the creation of the world, felt tired and delegated in men the continuity of his work.  For that reason as much in Sumeria, Acadia, Chaldea and Babylonia, and also in Egypt , the king or the Pharaoh was responsible to execute the divine will (teocracies) and his empires tried to be a reproduction of celestial order. 

         It is this mitification which has been able to deceive some investigators (and late deciphering of clay tablets written in cuneiform alphabet) that attributed to the Greeks and his logical-philosophical genius what legitimately we know now belongs to creators of the astrological patrimony of the humanity, the cultures of the Fertile Crescent . 

         We can see it words of one of the Spanish pioneers of the History of Science: 

         Until in the present days, of specialized maturity investigation, it has been possible to constitute with all the guarantees of a scientific discipline, the new called discipline History of Science, the vision that had of the evolution and the genesis of this one, as well as of the scientific legacy of the different cultures, it is very far from being able to call joust.  Without with it we want to prejudge that our vision is definitively right.  In general, that vision was partial, as much by defect of historical perspective, as by influences comings of the field of the religion or the politics, with its rivalries and factions, or of the philosophy with its multiple schools, all this disturbed the straight judgment of the facts… (6)

         Perhaps this partiality of judgment has to do with our Greek and Roman cultural ancestry (rather of the former, because it is known Rome little or nothing contributed to the scientific development, only to engineering), that, lost after the collapse of Roman Empire, he was reintroduced in Europe through the medieval Arabic expansion.  Nowadays no longer such partial and mistaken visions can be maintained: 

... This exaggerated interpretation of the Greek miracle and the scientific incapacity of  other cultures of the antiquity and the Middle Ages was elaborated between the people of the French Encyclopaedia and the nineteenth-century rationalism, and received force, according to before we have alluded, of philosophical, religious and political interferences, absolutely external to the straight critical judgment (7)   

         Not only appeared for the first time in the Middle East the phonetic writing and the place value notation of duodecimal and sexagesimal base (this last tied to the necessity of astronomical calculations purely scientist ns); appearance of big cities, together with intense commercial interchanges, favoured at first  mercantile Arithmetic, and later abstractions of purely scientist character.  Trigonometry was born as a instrumental way to the service of astronomical calculations. 

         Otto Neugebauer, who was professor of the University of Brown, showed (8)  in the decade of 1930 the high level that Mathematics reached between Chaldeans and Babylonian; arithmetical series, square and cubical roots, tables of reciprocal numbers, problems of  simple and compound interest, problems equivalents to resolution of equations of second and third degree, geometric problems of areas and volumes, etc., are in clay tablets.

         The place value position, essential for calculations and the development of science, was lost between Greek and Roman, and the scientific development did not take great steps.  The Mayans also invented an analogous numeration, allowed them calendaric precisions (mathematical) comparable.  With its reintroduction in Europe (Abraham Ben Ezra was the first Jew that used it in century XII) it could again advance measures and calculations, and with it, science returned to move again in Western world.  

         Observation of the sky in the Middle East was bound to the interpretation of the will of the Gods, but the necessity to predict celestial phenomena stimulated the scientific abstraction, and therefore Mathematics.  One of the greater profits of the priest-observers was the determination of the planetary cycles, as well as its repetition in the sky after a certain period of time.  Given the relative political and economic stability of the middle eastern societies in that period, these observations extended throughout centuries, which allowed to take the first important steps in astronomical matter.  And, more important for us, to find parallelisms (synchronisms of repetition, equivalent to tuning) with terrestrial events of similar period (resonance).

         If already there were an intuitive sensation of attachment to the cosmos between farmer populations (annual, vegetative climatic cycle, fauna, etc.), the long astronomical observations led to the priests to establishments of superior order, in which the origin of Astrology as science must be searched for. 

         Priest-observers stated that the cycle of lunar phases is repeated with much approach after 19 years (and therefore the cycle of the oceanic tides, etc.);  the same occurs with the conjunctions of Venus and the Sun, that repeat every 8 years just by two days of delay.  Such discoveries allowed the first astronomical predictions without great mathematical calculations.  We will see more ahead the physical interpretation of this fact and its possible repercussions in the alive beings and the integral parts of the great organism that is the Earth. 

         The European Middle Age retook these cycles brought by the Arabs and named great, middle and small years, according to the degree of precision; but the origin of this knowledge, again, we found it in the Middle East and not in Greece . Here we are a list of these cycles of repetition (tropical revolutions refers to a complete return of the planet in the Zodiac, and synodic periods to the time elapsed between two successive conjunctions of the planet with the Sun): 

Jupiter                   71              6 years rev. tropical = 65 synodic periods

Jupiter                   83              7 years rev. tropical = 76      "       "

Venus                    8                8 years rev. tropical = 5     "          "

Mercury               46               46 years rev. tropical = 145  "         "

Saturn                  59               2 years rev. tropical = 57     "         "

Mars                    47               25 years rev. tropical = 22   "         "

Mars                    79               42 years rev. tropical = 37   "         "

Moon                   19 years

         Until now, first horoscope available, found in a cuneiform tablet, is the one of 12-13/01/-409.  Demetrio Santos, translating On nativitatibus,  of the Arab Albubather, found another that, analyzed the offered astronomical data, calculations give for it the date of -1114. (9)  This continues delaying once more the dating of scientist knowledge , in a tendency that does not seem to stops.  Such horoscope provides the positions of the Ascendent, M.C., Full Moon previous to the birth of the boy, Lot of Fortune and seven visible planets to naked eye. 

         We see that it gives the positions of more important angles (oriental and meridian, that is, approximately, rising points and culmination of the stars), the ones of the seven planets, the one of the previous lunation to the birth and a complex point whose present mathematical meaning is the one of vectorial sum of two waves (Lot of Fortune). 

         Another great achievement of middle eastern science was the invention of the Zodiac of 12 equal signs, that, in spite of its present name, is of Greek origin either. The Babylonian Zodiac was stellar, unlike the Greek, that took as references the fictitious points from solstices and equinoxes.  The knowledge of Geometry led to the Greek astronomers to the discovery of the tropical Zodiac, and, with the calculations and measures that it allowed them, the precession of the equinoxes. 

         According to B.L. van der Waerden, in his article History of the Zodiac,  published in 1953 in Archiv fur Orientforschung: 

         The twelve zodiacal signs appear for the first time in planetary text VAT 4924 by 419 B.C.  The Babylonian signs are of equal size...  Lunar and planetary tablets, in which each sign contains 30°  confirm the conclusion that the signs have equal size.  (10)  

         It talks about signs and not about constellations, as demonstrate the analyses of the investigators who have studied the text. 

         The first systematized and structured Zodiac is therefore of Babylonian origin, and takes as references the fixed stars.  It does means that they ignored the phenomenon of the equinoxes and solstices; nevertheless, for that culture the exact determination of this point was not important. They preferred stellar references, that were those that better knew by their long experience in the knowledge of the firmament.  An error of 2 or 3 days in the observation of the equinox takes to another of about 8 minutes in the duration of the day, something that did not worry too much to Babylonian priests.

         The importance of the science of the influence of the stars at this time is summarized by Demetrio Santos in the following paragraph of Introduction to the History of the Astrology: 

          We can say that the period from -1200 to -400 marks the Golden age of  astrology, when more important advances and their fullness were obtained.  It begins with the expansion of the metallurgy of iron and the Phoenician phonetic writing and with it an intensification of the cultural evolution.  But the ostracism in which astrology has been sunk in the past Century [ XIX-XX ] in the West has caused that lacked its investigation in the European scientific blossom, and was not made a serious study of old texts related to astrology.  Nevertheless, all the data that we have at the moment converge to indicate their summit in the time and place of the mesopotamic cultures. (11)                

 

         The transplant to Greece

         As much Greek as Roman had an enormous respect by " the ancients ", when talked about the knowledge that came to them from the of East; if Greek science and philosophy, base of all European and western knowledge, were lost with the fall of the Roman Empire, it is easy to imagine what happened to the enormous amount of works that were generated in Mesopotamia throughout more than 2,000 years.  The major part of them disappeared, and the rest could not have been deciphered until the beginnings of century XX; even so, cuneiform  tablets can furnish to us surprising discoveries. 

         If we know enough middle eastern science it is because was transplanted to Greece , and there generated the explosion called " Greek miracle " in all fields of the knowledge. In astronomical and mathematical matters Greek science is particularly tributary of the Chaldean.  In astrological matter the transmission convert into a myth a personage called Beroso, who surely symbolizes the diaspora of Chaldean mathematicians, subsequent to the collapse of the empire: 

         It must grant that we can know the effects that the twelve signs, the Sun, the Moon and the five planets have on the course of the human life from the astrology and the calculations of the Chaldeans.  The geneatliac art, that allows them to discover passed and future events by means of astronomical calculations, is properly theirs.  There are many that have arisen between the Chaldean culture and have left us their discoverie, which are full of sharpness and wisdom. The first  was Beroso, that settled down in the island of Cos and there taught. (12)   

         All Western Astrology that we know summarizes in the compilation that carried out Claudius Ptolemy in century II;  their astronomical model of the world, geography and optics, even a treaty on harmonics, dominated the intellectual panorama until the European Renaissance.  Ptolemy lived and made its work in Alexandria ( Egypt ), but we can consider it totally Greek. Let us see what says about him the present Castilian translator of Tetrabible (medieval  Quadripartitum): 

         We cannot consider Ptolemy an original man, and he does not try it either;  he makes reference, when he knows them, to the sources, or always gives them as unknowns but previous to him.  He managed to compile, mainly in Astrology, the knowledge of his time and precedents, giving them coherent form and making them comprehensible, since he himself did not get to understand his real foundation and, before the difficulty, he rationalizes the facts treating to explain them...

         In spite of everything, Astrology begins in the West  suddenly ex- nihilo with Ptolemy, and in 1.800 years of history nothing new at all is invented  on the matter, except  small improvements and astronomical adjustments for the tables of movements of planets and to fix the positions of  stars that had varied by the movement of Precession of the Equinoxes.  And probably it occurred in that way because its text reflects what it was in his time  the great astrological culture of the Middle East, in special of Babylon, and his book constitutes a window, the only one, opened to such knowledge, having itself arrived at unremovable empirical rules that were useful. (13)   

         Beyond Ptolemy little thing has arrived until us somewhat different from his Tetrabible.  Shortly before him we have  Astronomicon, of Marcus Manilius, written in the firsts years of ours Era;  Carmen astrologicum, of Doroteo de Sidon, that also lived in century I, etc.  But we already see in those works a science in clear decay, and about this the astrologers in the Middle Ages will complain when verifying the existing discords between diverse authors.  

         We know through Diodorus (2, 29) the way in which learned the Chaldeans, unlike of Greeks, perhaps one of the necessary keys to understand the high levels at that they arrived in scientific matter: 

         The Chaldean philosophy is of familiar tradition; the son who inherits it of his father is free of all public obligation.  As the teachers are their own parents, they have advantage to learn without limits all those knowledge and to give greater credit to the words of its teachers. Accustomed to the study from the childhood, they advance quickly in astrology because of the facility whereupon it is learned to that age, or because they have more years to study...  The Chaldeans, always maintaining the same science, receive, without altering, the tradition; the Greeks, on the other hand... contradict among them about the most important doctrines (14)    

         A safe reference to know these subjects is the monumental work of Auguste Bouché-Leclercq, L'astrologie grecque,  published in 1899 and reedited in 1979;  but, in the summit of rationalist delirium, contains commentaries as the following one, that give some idea about the climate of hostility against the science of the influence of the stars at that time: 

         What is truth of  superstitions in general it is also with greater reason of  astrology, that somewhat has tried to connect  exact sciences as " mathematics”, the most adventurous efforts of the imagination. Astrology, once died - I believe that it is, in spite of the attempts made recently for vivify it- has been dealt with a disdain that does not have comparison with other questions of historical importance infinitely smaller (15)   

         We will return to this author, leaving aside some slippings as that we have exposed.  Meanwhile, we remember that we are talking of the epoch that Rome dominated all the Mediterranean basin;  later it arrived the Christianity, intellectual heir of Roman expansionism, the fall of the Empire and the barbarization of Europe. 

         To Greek science, characterized by high mathematical and philosophical speculations, followed a period more inclined towards the mysticism. Knowledge preferably were obtained by intuition or illumination (teurgy, contact with the divinity).  They were times in which neoplatonism, hermeticism and the gnosis, revived.  

         The science of the influence of the stars, been born next of Religion and Magic (time of sidereal religions, sabeus period), also lost part of its rational component and inclined towards aspects hardly imaginable for us at the present time.  The Christianity, on the other hand, adopted the cosmology of this time, immersed in astrological base. But Christianity did not show special inclination towards the rational science and sank in the mystical flow of the first centuries of our Era. Here we are the cause of the strong ideological conflicts that it had with the paganism, that in some occasions finished in blood baths. 

         Within the Roman Church the only bond that was with rational science was the necessity to be able to calculate correctly calculate the first Full Moon of the spring, essential requirement to celebrate Passover in accordance with the norms dictated in Council of Nicea (year 322).  It was a problem that lasted centuries without solving suitably, which gives some idea of the precariousness of medieval astronomical calculations. To carry out the reform of the calendar in year 45 B.C., and to date Passover after Council of Nicea, as much Julio Caesar as the Popes resorted to alexandrines astronomers, that is, Greeks, which illustrate where were settled the best scientist at those epochs. 

         After the fall of the Roman Empire, Europe was sunk in barbarism and ignorance (century V); the culture not only disappeared (of Greek base, the Romans were good legislators and technicians, but they showed little or null scientific inclination), but that arable lands were wasted and, mainly, communication routes.  The malaria reappeared, and to travel became dangerous, with the bandits threatening the routes. Commerce and cultural interchanges were reduced to minimums, thus arising what it has been called “the dark age”.

         Saint Isidore of Seville (560-636) constitutes an exception in this climate of decay and distrust towards science;  in Etimologias  he talks of the Zodiac and admits certain influence of the stars on the Earth and its inhabitants.  He defends the " natural astrology ", the one that deals with the effects of the Sun throughout the year and calendaric questions, condemning the " divinatory one ", that it claims to know the destiny of individuals. 

         In this unfavourable climate to the rational knowledge the emperor Justinianus commanded to close by real decree the old Greek schools of philosophy in 529, although hardly if they already taught some neoplatonism bathed of mysticism and Christian elements.  

         The little of the old knowledge that remained took refuge in the monasteries, waiting for more propitious times in Europe . 

 

         The Arabs and their transmission to Europe in the Middle Age

         The collapse of the science and the ways of life was general; at the same time that culture and science reached in Europe their lower level, in Bizancio and the countries of the Near and Middle East - Syria, zone of the Persian Gulf - survived a remarkable cultural center, mixture of Greek, Roman and Jewish elements. One of its first centers was the Persian school of Jundishapur , a place where they found refuge the nestorians Christians accused of heresy in 489 as much the neoplatonics which they left Athens when the Academy in 529 was closed. 

         In this place the Greek science and philosophy were recovered, and simultaneously made contact with the ones of India , Syria and Persia .  Later they would be the Arabs who would retake the torch, and thanks to the translations of all ancient work that they found and also of their own achievements, was reintroduced in Europe the lost knowledge.  The Islamic connection with the Iberian Peninsula is one of the keys for understand how Eastern science and the culture reappeared in Europe after 1200 years of the fall of Babylonia, although filtered to a large extent through the Greek authors; numerous orientalizant elements are still presents in medieval architecture, and, of course, those that are only interpretable under the prism of that knowledge and that cosmology.

         We have the arc of mid point and barrel vault in romanic architecture (planetary concentric spheres of Eudoxus), mozarab (eccentric of Ptolemy), planetary epicycles (cloister of Saint John of Duero, in Soria, Spain), Jupiter in front door of Saint Peter’s Rúa, in Estella (Navarre, Spain), with his eleven lobes (the ones that it draws up the planet in the sky during a complete revolution zodiacal), etc.  The medieval temple reproduces on scale the macrocosmos (planetary skies), trying to imitate its effect on the man; for that reason it is constructed on the basis of harmonic proportions (and not by simple calculation of resistance of materials), it is oriented (with the apse invariably towards the East) and contains manifold astronomical elements, real and symbolic, expressed through the Christian doctrine, that was not alien to the cultural climate of the medieval epoch. 

         In the Middle Ages it is possible to be said that everything comes from East, with the Arabs or the crossed as messengers;  they brought Geometry, Arithmetic, Algebra, Trigonometry, Alchemy, hippocratic Medicine and numerous Greek works, translated to the Arab. Plato, Aristotle, Euclid, Ptolemy and so many other authors, that they had lost for Europe during several centuries, return to be read, and mainly longed for and looked for with avidity in the Christian world, still sunk in cultural lethargy:

         Meanwhile, it was not a secret in Europe that in their retirement [ with the Reconquest ] the Muslims had left in Christian hands so many  books, books that  Europeans of the North of the Pyrenees - it does not seem that Spanish clergymen thought the same, they preferred to fight instead of read- wished to learn and study. For that reason, an important number traveled to Christian Spain (not to the Muslim,  where there were still better libraries), they learnt Arab and was able to translate the books that the bishops lent them, who had confiscated them of the libraries of the defeated.

         An important element of the transmission was the place value notation in numbers (that we still use at the moment), in which the value of a number depends of the position that occupies (units, tens, hundreds, etc.); neither the Romans nor the Greeks knew it, in spite of coming from the sumers   (third millenium before ours Era).  From there it went to India , the Arabs took them and travelled to medieval Europe in XII century. 

         This system is essential to make calculations, to develop equations and, in general, all Mathematics applied. Christian scientific knowledge, compared with the Arab, was certainly incipient, which can be verified comparing works of both fields written simultaneously;  the Tractat d'astronomia  of Ramon Llull, or Nova Geometria,  of the same author, is of inferior quality than other similar contemporary works of the Arab world.

         In the middle of a cultural and social explosion which they made of Cordova the capital of the world in its time, Astrology was one of sciences in which they honoured the Muslim wise people; but that science of stars basically came from the hand of Ptolemy and few more authors, that is to say, it was translated Greek science, that is, Chaldea, to which without a doubt they made some contribution.  Tetrabiblos  and Almagesto (Syntaxis Megalé  or Gran Composition)  were the more advanced of the astronomical science (and astrological) of those moments;  Alfonso X, king of Castile, dedicated a great part of his efforts to translate to the Castilian and Latin  the Muslim astrology in century XIII.  Under his supervision was made among other works,  the Libro Conplido en los iudizios de las estrellas [Complete Book in the judgements of the stars], of Aly Ben Ragel, a compendium of medieval astrology. The original manuscript is in the National Library of Madrid.  In 1954 Gerold Hilty, a North American scholar, published the transliteration; in 1997 were published two adaptations to a modern Castilian. In 2004 it was being translated to the Russian, one of the few important European languages to which this work had not been known.  So, the astrological revival seems to be in a good moment at moment. 

         An important element of Libro Conplido  is that it speaks clearly about discrepancies in the astrological doctrine from Greek authors, that is, in Hellenistic epoch the science of stellar influence already had entered into decay; it dedicates to this subject a section of the fifth Chapter of Book I, Aphorisms in discords of the ancient wises.  Ben Ragel mentions Ptolemy, Dorocius (Dorothy of Sidon), Vuelius (Vetius Valens of the Latins) and Hermes, to which he adds others of his cultural surroundings (Messeallah, Atebary and Abnelfarhan).

         It interests to us to stand out here that, under the apparent splendour of medieval Muslim science, the precariousness of the observations and astronomical calculations becomes now quite evident, and this for two reasons:  first, the lack of an suitable mathematical apparatus (to deal with waves, that is, vectorial calculation, harmonic analysis, complex numbers, etc.), and second, the deficiency of instrumental precision (the telescope did not appear until the Renaissance, in century XVI). 

         The failures in astrological predictions were generally attributed to these defects of the calculations, not to failures of the doctrine (except for some exception, as the jew Maimonides, that criticized the divinatory astrology from its deep knowledge of astrological doctrines).  These failures had a positive effect in the stimulation of the advances, as much astronomical as mathematical.

         We can imagine the difficulty and cumbersome of the calculations for casting an horoscope in the Middle Age; to obtain the position of a planet with the Alfonsies Tables required half an hour of work for an experienced computer, and to cast an complete horoscope about four hours (17)  In many cases astrologers were satisfied calculating the average positions of planets by means of simple rules, not the true positions;  in other words, it was sufficient to determine the sign where the planet was. 

         The use of both fixed Zodiac (virtual) and the stellar simultaneously as reference also contributed to commit errors and confusions; in fact, there were in use two systems that, for example, when determining the entrance of the Sun in the signs (and therefore of the astronomical stations), implied discrepancies of about six days in century XI (theory of the observation and the Sindhindi, this was brought by the Arab astronomers of India). 

         The lack of precision in the determination of solstices and equinoxes (or, which is the same, the insecurity in the calculation of the beginning of the astronomical quadrants of the year) suggested the use of the great Christian religious buildings as astronomical observatories (meridian lines).  The procedure consisted of opening a small hole in a wall oriented to the South, and to observe the luminous spot on the pavement at the moment for passing the Sun through the Meridian (12 o’clock solar hours).  The light cycle draws along the year a swing  movement that determines an air line in the pavement, easily observable in the dark of the churches; the  nearest of the wall comes the day of the summer solstice (Maxima annual height of the Sun), and the most moved away in the winter solstice (minimum altitude).  The determination of the equinoxes had other instruments coming from ptolemic Astronomy, as armillary metallic or the quadrant. Worse or better conserved, accessories of this type or similar still proliferate in the churches and Christian cathedrals; they are specially remarkable by its contents and state of conservation those of San Petronio in Bologna , Santa Maria del Fiore, Santa Maria degli Angeli in Rome and the Duomo of Palermo, all of them in Italy . There are also two meridian lines in San Lorenzo del Escorial ( Madrid , Spain ).  The great dimensions of this type of instruments intended to improve the measures and to avoid errors in the dating of Passover, although astronomers also determined with them the accurate inclination of the ecliptic and the duration of the year. 

         If this happened to such astronomical elements in the Christian temples, the advances of Astronomy had the exclusive object of avoid errors in astrological predictions, attributed as we said to deficiencies in the calculated position of the planets.  The effort of the equipment reunited by Alfonso X the Wise crystallized in the preparation of the so called Alfonsies Tables, already mentioned, and very used in all Europe until Copernicus elaborated its new model of the world in century XVI.

         During century XIII already was knew that astronomy of Ptolemy took to discrepancies between predictions and the observation, but almost nobody questioned the model, consisting of a fixed Earth and the planetary orbs turning around to it in a complicated system of deferential eccentrics and equants. The astronomical model was tie closely to religious elements from the Antiquity; in this system it was considered that mortal creatures inhabited the Earth, the Gods and the souls of righteous the Mount Olympus , and those of unjust the Hell.  It already was thus in the days of the Greek Aristarch of Samos (-310/-230), who when daring to propose a system with the Sun occupying the center of the world was erased to fall in the ungodliness. In the Islamic world, Bassar b. Burd was punished by some verses in which it was said that the Earth is dark and the fire shining (primacy of the Sun, of which the angels had been created, over the Earth), contradicting to Corán 2, 32-34,  where it affirms that Adam (formed of earth) is over the angels in the hierarchy.  For that reason he was accused of Mazdaism and died because of the torture with he was punished (18)  

         Astronomy went on its advance unstoppable, and in century XV, the increase of the commerce and navigation added a new incentive to perfect the tables and the observations of stars; it was the dawn of the Renaissance.  With the arrival of the press a true literary explosion began (interchanges of intellectual type), and few years later Europe discovered the New World .  Astronomical precision became more and more necessary to locate the ships in its passages by means of the measurement of the height of the Sun (determination of the latitude during the day) and of stars at night.

         Astronomy advanced, but not Astrology, stagnated in no other activities that the repetition and copy of old works; the lack of new observations of the influence of the stars, and of new theories, the model of the planetary spheres, the Principle of  basic uniqueness of the nature, the harmony and tuning between Sky and Earth as basic postulates of ancient science, went fossilizing in old, invariable and obsolete dogmas. 

         Even it continued present in the society some more centuries, until disappearing almost completely of the scientific panorama between XVII and XVIII centuries.

 

         The Renaissance declivity

         During centuries XVI and XVII the European way of life underwent an authentic revolution in all the orders.  We are going to be centered here in some particular and little known aspects of the declivity of the ancient concepts, also denying certain current errors that still circulate without no objective foundation.

         The fall of the ancient science (and with it of the Astrology) usually is attributed to the combined effort of certain authors, basically Nicholas Copernicus, Galileo Galilei, Johannes Kepler and Isaac Newton.  We cannot enter into the consideration of these authors from the point of view of our own time, ignoring the moment that they lived, if we want to approach to the true way to think and to focus the things correctly.  It is certain that the four mentioned, and others of the same epoch, gave a crank blow that changed radically the way to see the world, but that was not absolutely their intention, nor worked with that objective. 

         The History of Science has not clarified the last motivations that incline to Copernicus to propose a model of the world with the Sun in the center and the Earth turning around it;  we can say that it knew the astrological system, as any cultured man of his time, and that, in spite of defying a worldwide vision that was effective fourteen centuries ago, its new model continued being compound of planetary spheres, not of simple planets orbiting around the Sun, as it is conceived at present time.  This detail, fundamental for us, is systematically ignored by the critical of Astrology. 

         They affirm that Galileo Galilei was a detractor of astrological system, when the certain thing is he knew its techniques; but he had bad luck when predicting long life to his protector the great Duke of Toscana, Fernando I of Médicis the 16 of January of 1609 (been born in 1549), that died few weeks later (19)   The bitter character of Galileo took him to a visceral opposition front the beliefs of the astrologers. But still was more radical his intransigence with the scholastics, that is to say, the orthodox scientists of his epoch.  Galileo was extremely revolutionary in undertake the study of natural phenomena since we do today, by means of application of mathematical calculation and experimentation. 

         The works of Aristotle were known again in Europe through the translations of the Arabs;  in century XIII Saint Thomas of Aquino had a great incidence on the medieval thought reconciling aristotelian science, specially the Physics, with the Christian theology.  Through his Summa Theologica  Aristotle became an unquestionable authority in philosophical as much scientist matters. The followers of Saint Thomas were known with the name of " men of school " or " scholastics ", settling down themselves as unquestionable authorities in the European universities arisen from the Middle Ages. 

         In De caelo,  Aristotle settles down a radical division between the terrestrial and the celestial world;  for him, terrestrial or the inferior world is constituted by four Elements (Earth, Water, Air and Fire), passive and subject to the circulation of the seven orbs (planetary spheres) with its seven wanderer stars, plus the eighth of fixed stars, that are active and determine the terrestrial events.  The sky is made of a fifth Element or Quintessence.  For Aristotle the spheres constitute " separated intelligences " (they follow an perfect order) that, in version of the three great monotheists religions they are " angels " or mediators between the divine will and the humans who live in the Earth. 

         We can see this cosmology repeated in most of medieval texts with slight variants and also has strong religious connotations; for the astral religions of the Antiquity the souls of men are of celestial nature, from the heavens come to incarnate in a terrestrial body, and from the Earth start off with the death.  The Earth constitutes a crossing site and everything what there is in it is born to die (he is subject to generation and corruption); the Christianity will locate the saints beyond stars, and, presiding everything, Christ Pantocrator. 

         Within this cosmology, in agreement with Plato and other authors, the planets, the Sun and the Moon, are Gods (creative and governing agents of the inferior world); its bodies, perfectly round; the movements, perfectly circular and uniform.  The sky, with all divine thing that contains, is eternal and immutable, no change can happened in it, neither generation nor corruption.  On the other hand, in the Earth the bodies move in straight line (they fall following the vertical), looking for " their natural place ".  To more weight, they descend with greater speed (Aristotle); of course, the Earth remains immovable, as " precipitated " and passive subject of the upper world. 

         Galileo developed a new Kinematics, applying equations to the movement of the bodies, as young people studies in High School; in the famous tower of Pisa (Italia) he verified that heavier a body is it does not descend with greater speed, refuting Aristotle and all his scholastic followers. By means of a telescope he verified that the Sun showed variable spots for a day to another (already known in China thousand of years back), the Moon had a very rough relief, with seas and mountains, Venus showed phases like the Moon and, most surprising, around Jupiter four small satellites moved.

         The immutable skies of aristotelian cosmology presented variability, and the Gods, some imperfections!  Even the Jupiter moons broke the scheme of " esoteric number seven ", the great dogma of ancient old-fashioned science, already in unstoppable declivity: 

         There is seven windows in the face, two windows in the nose, two ears, two eyes and one mouth;  thus in skies there are two favourable stars, two nonpropitious ones, two lights, and a single, and indecided indifferent Mercury.  From which and other many phenomena similar of the nature like the seven metals, etc., that would be tedious to enumerate, we arrive to the conclusion the number of planets necessarily has to be seven...  In addition, the Jews and other ancient nations, and also the modern Europeans, have adopted the division of the week in seven days that call them by the names of seven planets; however, if we enumerate the number of planets, this system falls by its base...  In addition, the satellites [of Jupiter] are invisible for the naked-eye and therefore they cannot have influence on the Earth, so do not exist (20)   

         We see the degree of simpleness and pride that can reach the human mind when is put it in hardships. Galileo devoted a combative work to the defence of the heliocentric model of Copernicus and to his own ideas in Physics and Astronomy (Dialogue on both maximum systems of the ptolemaic and copernican world). (21)    His determined defence of this ideas took it to the sentence of the Roman Church. He retracted of them in June 22 of 1633;  previously, De revolutionibus of Copernicus had been condemned March 3 of 1616. 

         Our next personage, Kepler, is another of the creators of the foundations of modern Physics, in spite to be a convinced and practitioner astrologer, with an evident Pythagorean and mystical inclination;  in order to verify this it is enough to read his works, that are continued publishing with certain regularity, which has not been obstacle so that some critical have had daring to affirm frivolously that it condemned Astrology and that, if he made horoscopes and published annual meteorological predictions being based on the planetary events and aspects, it was due to economic necessities. 

         The certain thing is that Kepler was the last great European investigator in astrological matter, one of the few people that in XVI-XVII centuries investigated and made science on the influence of the stars in the Earth and its inhabitants; at present several astrological software and some publishing house dedicated to ancient science take their name. 

         Kepler contributed to the failure of the dogmas dragged by the scholastic with the three physical laws that take their name (and, by the way, our bachelors continue studying); the fine astronomical observations of Tycho Brahe (Kepler collaborated with him), and that took to their discovery.  The first and the second laws were demolishing for the aristotelian Physics:  the orbits of planets are not circular, but elliptical, (although of low eccentricity) and the Sun occupies one of the two centers, contradicting so much the position and Earth fixedness as the fact that the Gods, only can draw up perfect circles (Eudoxus, Aristotle, Plato, etc.). The second  law affirms that the planets do not travel at constant speed, but that accelerates in the perihelion (minimum of distance to the Sun) and they go slower in the aphelion (maximum distance).

         As we see, neither the first law nor the second contradicts the basic principles of ancient science, but certain way to go into the problem to determine the movement of the stars by mathematical calculation. They do not refuse the planetary influence either, one of the subjects that Kepler dealt in his works (Mysterium Cosmographicum  [ The secret of the universe ], Harmonices mundi  [ The harmonics in the world ], De fundamentis astrologiae certioribus  [ On the very certain foundations of the astrology ]). 

         Some years after Kepler worked in the present Poland did Newton in England ; he definitively drew up the bases of modern Physics with the shattering success of his laws in Mechanics, Gravitation, Optics, etc.  With him was born a world, the " Newtonian world ", that dominated Physics until century XX. Only then appeared breaches in this building that seemed solid and definitive. 

         Newton’s conceptions were demolishing for the aristotelian Physics and Cosmology, that already had began to show deficiencies and errors, mainly in Cosmology (Law of Universal Gravitation): only one equation describe both the free fall of a body in the proximities of the terrestrial surface and the movement of the Moon, breaking the dogma which affirms the laws of the terrestrial world nothing have to do with those of the celestial one. 

         Newton ’s Mechanics was enough and complete to describe the dynamics of the bodies (free fall, movement of projectiles, friction, rotation, gyroscopic effect, etc.); by means of Newton ’s laws could be deduced the three empirical laws of Kepler and improved enormously astronomical calculations with the new heliocentric model of Copernicus.  Newton’s discoveries and interpretations in matter of Optics dazzled the scientific academies that began to arise by Europe, and stimulated their growth in the next centuries. 

         It would seem therefore that Newton can be considered a man of present epoch, or one ahead at his time, but this can take to mirages of intellectual type;  he was not rationalist, Newton was in the antipodal intellectuals of the mechanist thought that his work originated.  The historians of science advice to us:  Newton not only believed, but cultivated Astrology and Alchemy, very current matters in his epoch;  and he worked in those fields by personal urge, neither by ambition to leave printed his name for the future, nor by desire of wealth: 

... the main object of Natural Philosophy is to infer from the phenomena, without preconceived hypotheses, and to deduce the causes of the effects, until arriving at the First Cause, that certainly is not mechanical;  and this not by desir  to separate the world of the mechanics, but to solve mainly these and analogous questions.  What is in the almost empty places of the matter, and where comes that the Sun and the planets gravitate to each other, without dense matter among them?  From where that the Nature does not do anything in vain?  And from where it arises the order and beauty that we see in the world?  Which is the aim of comets and why the planets in the same way move all of them according to concentric orbits, whereas the comets do it according to a great variety of orbits of great eccentricity?  And what prevents to fixed stars to fall on others?  From where it comes that the bodies of the animals are comprised with such an art and such aim their different parts?  Was formed the eye without ability for the optics and the ear without knowledge of the sound?  How come the movements from the body of the will and where comes the instinct to the animals?  Is not sensitivity that place in which is the sensitive substance in the animals and to which transmit the sensible species of the things by means of the nerves and the brain to be perceived by its immediate presence before the substance?  And being all these things so straight established, it does not appear clear by the phenomena, the existence of an incorporeal, Living, Intelligent Being, Omnipotent, that, in the infinite space, as if it was his sensitivity there, sees the intimate of the things, he totally perceives them and understands by his immediate presence before Him, and only the images of the things transmitted by the organ of the sense to our small sensitivity are seen and perceived by what about us he thinks and perceives?  And it also does not keep all step to us in this philosophy to the immediate knowledge of the First Cause and more near of it, and for that reason we has to have it in great esteem? (22)   

         In a letter written in 1692, Newton gives account to a friend about the intentions that took to him to write Mathematical Principles of Natural Philosophy, one of his more remarkable works:  

         When I wrote my treaty [ Principia, 1687 ] about our system, I had the intention of which the exposed principles took to men to the consideration of the faith in a Divinity;  and nothing has cheered to me more than to know them useful for my intention (23)   

         Our way to see the world from the present thought distorts the real vision of the discoverer of the Law of Gravitation, that, convinced Christian, in the final escolio of Principia says: 

         The six main planets turn around the Sun in concentric circles to the Sun, with the same direction of movement and approximately in the same plane...  And all those regular movements do not have an origin due to mechanical causes...  So elegant combination of the Sun, planets and comets only could have origin in the intelligence and power of an intelligent and powerful being...

         It [ the Sun ] governs everything, not as soul of the world, but the owner of all.  And by its dominion, he usually is called Lord Pantocrator (24) ..

         At the end of his Opticks  Newton reaffirms himself in this idea admitting that the perturbations produced in the planetary orbits by the mutual attractions of planets would finish, without the vigilant control of the Providence , destroying the order in the Solar System (25)                    

                    

         The position of the Church

         As much the Christian Churches, as the Judaism and the islamism, have maintained difficult relations with the cultivators of the science of the influence of the stars, because to foretell human fate put in question the divine will as much as the freedom of election in the humans.  In any time and place there are subjects for which things only can be white or black, when the reality is much more varied and colourful; Ptolemy, the great authority of Western Astrology, already cleared the problem when seating that " the stars incline, but do not force ". 

         Enrique de Villena, in his Treaty of Astrology  (1428) says to us that: 

         ... Astrology parts in two parts, that is to say, one that deals with the movement of all the heavens, judging the weathers before it come. About this there is no doubt.  The other deals with elections, and  this is subtle and bad of have.  And of this is opinion if we can use it without sin or non;  and of this are known the epidemics, births of men and illnesses, wars and deaths of the kings, and other many things, trough the science explains. This is reproved some doctors of the Holy Church (26)                

         In the Book of Good Love [Libro del buen amor]  the Arcipreste de Hita also gives his opinion on the matter: 

         I believe the astrologers naturally true;

         but God, that made nature and accident,

         He can alter it  and to make other way: 

         according the catholic faith in this I am believer. (27)   

         This ambience of relative tolerance was broken at the epoch of Council of Trento.  Peculiarly, De  Revolutionibus Orbium Coelestium  of Copernicus, published in 1543, it was dedicated to Paulo III, the Pope that, after several attempts, could finally summon the Council  in 1545.  During 1559 Paulo IV created the Prohibited Book Index, and in 1563 were established the rules to evaluate what texts could enter in it.

         We have spoken of multiple astronomical constructive details in the Christian temples, even of astrological cosmology; the God Janus is present in some cathedrals, as much the signs of the Zodiac, the planetary spheres, representations of synodic cycles, etc. The Council of Trento specifically prohibited any reference alien to the most orthodox Christianity in sculptures, pictures and texts. So, united to the astrological declivity of centuries XVI and XVII, with the increase of the new scientific paradigm and the new trends of the Holly Catholic and Apostolic Roman Church (and the Reformed one of Lutero played a similar role) came to finish off the science of stellar influences.

         A document of the Inquisition dated in 1584, Opinion onAstrology and ninth rule of the catalogue [Parecer de la Astrología y regal novena del catálogo], condemns the use of magic and witchcraft in Spain , but still maintains this in astrological matter: 

         His Grace and Most Reverend Sir:

          With this Rule 9 that Holy Office has established with communication of some scholars on the communication apparently disordered of the Astrology, I say that whatever the cause is pious more and the reasons apparently are more urgent as much would be their more harmful prohibition and of greater disadvantages than I fear would be increased (although only the scholars very experienced in Astrology can warn, although they are not enough learned well and without experience of the several things that always are offered in long speeches) and thus is necessary precedes in it the consideration that requests the quality of the matter, because of where it is only tried to guess right in the remedy of some abuses (that  I deny) could be greater and more irreparable those than were increased again, that those that is desired to avoid...

         We permit the treated books and written that teaches to us by the births and their directions, revolutions, profetcions and transits of the planets, to know the corporal inclinations, conditions, qualities and diseases of  men and the accidents and effects that in them natural and physically by the movements of the heavens are accused,  mean and understand, by the speeches of the several commissions of planets and their aspects and movements.

         Also are allowed the books treated and written necessary for the knowledge of the times and general events of the world, as for elections and natural observations that according to the heavens and stars and their several movements have respect correspondence and harmony with the births and revolutions, births as of the world considering that everything what thus by good and lyric Astrology it is allowed, can be and not to be and that only is come in it with fallible conjectures. 

         In the same way are allowed the judgments and natural observations that are necessary  to Medicine, Agriculture, Constructions and Navigations. (28)      

         This ambience of relative permissiveness finished just one year later, when Pope Sixto V, in 1585, promulgated his Coeli et Terrae,  in which prohibited " all the arts that deals the future events, with the exception of which by natural causes necessarily or frequently they are followed ".  From then, according to the Roman Church, Astrology will be allowed whenever is applied to Medicine, Agriculture and Navigation, but will fall in crime " the astrologers that with vain superstition by observance of the day of birth or another one, presume and affirm the state, condition, duration of life, honours, wealth, succession, health, death, ways, fights, enmities, jails, several crimes and other cases of prosperous and adverse the humans, attributing to the stars which is born of the free will of them, having to know that the stars became by the man and not the man by the stars”.

         It was specifically prohibited therefore the Judicial Astrology; the Inquisition published its Proclamations of Faith against the practitioners until the end of century XIX.  The border between allowed and the prohibited thing it was always difficult to determine;  under protection of their almanacs and medical practices, the astrologers filtered some predictions, but already the general atmosphere was for them more and more hostile.  And astrologers no longer were in conditions for the regeneration of a science they ignored its physical bases, because the new emergent science hit frontally the old postulates (it separates the man of the Cosmos, the part of the whole, is analytical and reduccionist, exclusively rational and progressively positivist and materialistic). 

 

         The rationalism and the burial of Astrology

         We have seen that who drew up the foundations of modern science did not proposed at all to ruin the basic principles of the ancient knowledge; but life is movement, change and transformation, and, as Aristotle sentenced, in this lower world everything is subject to generation and corruption, to the birth and the death.  Or, still better, according to ancient Middle Eastern science, everything is subject to cycles, appears, reaches to its maximum splendour, declines and disappears, then reappear some time later, as the Sun and the stars every day, every night, every year, each simple or composed cycle. 

         The last Spanish astrologer of fame was Don Diego de Torres Villarroel, who had the chair of Mathematics at the University of Salamanca ; when the astrological building was falling he still was able to foretell with success the French revolution, as it can be verified documentarily through his prognoses of year 1756: 

         When the thousands you will count            Cuando los mil contarás

         with three hundred dubbings,                    con los trescientos doblados,

         and fifty duplicates                                     y cincuenta duplicados

          with nine tens more,                                  con los nueve dieces más,

          then, you will see it,                                   entonces, tú lo verás,

          miserable France , it hopes to you              mísera Francia, te espera

          your last calamity                                      tu calamidad postrera

          with your king and your dolphin,              con tu rey y tu delfín,

          and it will have then his end                     y tendrá entonces su fin

          your greater first glory.                             tu mayor Gloria primera.

         De Torres was involved in bitter controversies with Benito Jerónimo Feijóo, a declared enemy of all thing related with noncatholic superstitious beliefs, and, of course, with Astrology.  The same opinion maintained Doctor Martín Martinez, author of a Final Judgment of Astrology in defence of Universal Critical Theatre divided in three speeches.  Speech first:  Astrology is vain and ridiculous in the Natural thing.  Speech second: Astrology is false and dangerous in the Moral.  Speech third: Astrology is useless and harmful in the politic (1726). 

         The answer of Torres, a satirical and quevedian author, few and far between, consisted of his Burial of final Judgment and vivification of Astrology, hurt with three sores to natural, moral and political, and cured with three patches: Astrology is good and certain in natural, true and  safe in the moral, useful and beneficial in politics  (Seville, 1727).  It arrived times of jokes, and the emergent side did not remain short in them. We have another example in The very small Piscator by the sky and the others by earth.   Journey dreamed between roosters and midnight, in which Astrology is undertaken, and simultaneously is made the Astrologers see the Stars  (Antonio Ángel de Fravega, Burgos , 1767).  The ambience against the whole ancient knowledge was gaining the fight every day and the only astrological texts published would be the almanacs, that, whatsoever, would enjoy (and still do it at present) of a great popularity, specially in rural ambiences.

         But everything evolved against Torres and other practitioners, who, as much theologians, clung to the intellectual forms of Aristotle; it seems pathetic nowadays their rebuttals, plenum of the burlesque acidity that characterized them, when refused a consequence of the Newtonian Mechanics, that the Earth, due to its turn, cannot be a perfect sphere, but  must be flattened by the Poles.  The arguments against Newton (29)  cannot be poorer and dogmatic, resisting even to verifications and measures of the French geodesists, that had demonstrated the veracity of the theoretical prediction. This was only one subject between others which questioned the Physics and the aristotelian system of the world. 

         Lacks of intellectual sap necessary to reanimate the dying, both astrologers and theologians were fortified in their old obsolete dogmas, devoted to the authority of the " ancients " and religious " revelation ".  Outside, the winds of rationalism and positivism blew with uncontrollable force;  the University of Salamanca , that had been permissive teaching Copernicus during century XVI in its classrooms, still had prohibited in 1770 Newton , Gassendi and Descartes. Their sin was to contradict the revealed truth and Aristotle (30)   

         The vigorous development of Mechanics initiated by Newton culminated, supported by the new climate of opinion, in a science based on the analysis of the parts and the systematic experimentation.  From ancient Astrology was born modern Astronomy, and later Astrophysics; from Alchemy, Chemistry.  New branches as Geology, Botany, Biology, etc., nourished a scientific tree more and more diversified.  Physics was divided into Mechanics, Electricity, Magnetism, Optics, Thermodynamics, etc., and, within each branch, new specialties arose. 

         Science definitively became independent (and for the first time in History) from the religion, giving birth to a totally materialistic teaching (we already saw that Astronomy, Magic and Religion were born together, and how Newton when speaking of these subjects expressed itself, so different from which would come later).   In this climate of disrepute by the ancient conceptions, chemists believed to have destroyed the vitalistics doctrines (which assured that the alive beings had something beyond the matter that maintained and ordered its characteristic functions) when in 1826 Hennell obtained a synthetic ethanol preparation and in 1828 Wöhler did the same with the urea, starting off of acid hydrocyanic and ammoniac.  In fact, such syntheses and those that came later, only demonstrated the incipient condition was still Chemistry in century XIX if we compared it with the present time.  " Organic Chemistry " (thus called, because it thought that only the alive beings could synthesize this type of compounds of their metabolism) is now more suitably denominated " Carbon Chemistry ". 

         But that was not all. New planets in the Solar System were discovered;  Uranus (1781), Neptune (1846) and Pluto (1930).  At this point, the dogmas of the septenary, the planetary spheres and horoscopes, no longer nobody remembered in the University.  Astrology did not teach anymore in Paris from 1666; Diego de Torres Villarroel (1769) no longer had substitute in Salamanca University and Valencia also lost its chair. 

         The new vision of the world, analytical and reduccionist, has allowed to incredible advances centuries back in the knowledge of the nature. But, as everything subject cycles, as time has passed by, also has left glimpse the first fissures, the first weak points.  When the scientific building seemed to be finished definitively, in the hinge of centuries XIX-XX, when the human thought penetrated for the first time in the microscopic world of atoms, everything came down (Planck, 1900, Einstein, 1905, de Broglie, 1920, Heisemberg, 1927, etc.).

         A few decades later it could be stated that, again, the doors were open for the ancient way to contemplate the universe.  And, simultaneously, came up again a noticeable astrological movement all along Western world. That is for we expect another revolution in the world of macrocospics.
