In addition to the Arabic commentary on the Tetrabiblos made by Ali ibn Ridwan Haly in the 11th century,  significant attention is given to an anonymous Greek Commentary , which has older, obscure origins. It was written at an uncertain date, in either late antiquity or the Byzantine period.
This is also attributed to Proclus, as the presumed author of the Paraphrase , although Heilen has remarked that such an attribution "looks like guesswork". The Greek Commentary was first printed in with an accompanying Latin translation by Hieronymus Wolf. This claimed to be based on a heavily corrupted manuscript which required numerous conjectures by a scholarly friend of Wolf, who preferred to remain anonymous rather than face reproaches for "dabbling in this sort of literature".
The purpose of the Commentary was to offer demonstrated illustrations and fuller explanation of the astrological principles described by Ptolemy.
Ptolemy’s Four Books on the Influence of the Stars () – GOHD Books
Following Wolf's edition, large passages were incorporated into Latin astrological works which featured extensive collections of example horoscopes. The Centiloquium 'one hundred sayings ' was the common Latin title of a collection of important astrological aphorisms. Early manuscripts were commonly accompanied by a commentary on their use authored by Ahmad ibn Yusuf al-Misri — The earliest translations were made by Johannes Hispanensis in and Plato of Tivoli in Ali ibn Ridwan Haly , who had produced the Arabic commentary on Ptolemy's work, noticed that the aphorisms highlighted principles of interrogational astrology, and wondered why Ptolemy had not included coverage of these themes in his Tetrabiblos.
By doing so they caused men to ascribe their own works to the ancients". The authorship of the text is now ascribed to "Pseudo-Ptolemy". Some scholars suggest that Ahmad ibn Yusuf was its true author. From Wikipedia, the free encyclopedia. Tetrabiblos Quadripartitum Opening page of Tetrabiblos : 15th-century Latin printed edition of the 12th-century translation of Plato of Tivoli ; published in Venice by Erhard Ratdolt , This doctrine is no simple matter, nor unrelated to others, but in complex fashion derived from the domination of the places of greatest authority.
Translators of the Tetrabiblos and associated texts. Main article: Centiloquium. Analogies between the status of the Tetrabiblos in astrology and the Bible in Christianity are frequent. See for example Riley p. I 'A vindication of astrology', p. See also Thorndike vol. Details of these texts and other translations are given in the section on Editions and translations.
It is one of the most important and influential works in the field of astrology See for example Tetrabiblos I. Broughton describes its value to astrologers as "One of the best books the student should read, and which is most essential" p. Hamilton and N. Most contemporary sources give c. Robbins gives — 'Introduction', I p. Mark Smith also veers towards the figures given by Robbins: "It is said that he lived to be seventy-eight and survived into the reign of Antonius Pius' successor, Mark Aurelius — These two claims, if true, would lead us to place Ptolemy's death not only somewhere within that span, but probably toward the end".
But Ptolemy is clear that even if it is less certain , astrology is more useful than astronomy". Ptolemy's arguments were used by Kepler in his text, De Fundamentalis Astrologiae. Retrieved 4 September In his commentary on the Tetrabiblos Jerome Cardan gave the example of those who give elaborate predictions based only on the day or month of birth. Most of book II is given to exploring the stereotypes of nations in astrological terms. Why, even a mortal, if he has a proper sense of duty, does not warn his friends of imminent disasters which can in no way be escaped".
See also Riley p. The first quarter of the synodic cycle brings an added emphasis on moisture; the next increases warmth; the next in which the cycle is receding withdraws the moisture and brings an added emphasis on dryness, and the final quarter which closes the cycle withdraws warmth and brings an added emphasis on coldness. The Ascendant is the eastern angle, associated with the east wind Apeliotes which excels in dryness; the midheaven is the southern angle, associated with the south wind Notus which excels in heat; the descendant is the western angle, associated with the west wind Zephyrus which excels in moisture; and the Imum Coeli is the northern angle, associated with the north wind Boreas which excels in cold.
However, it is clear that Ptolemy was merely following convention, as demonstrated by Geminos's Introduction to the phenomena , 'On the Circle of the Signs' ch.
For if other starting-places are assumed, we shall either be compelled no longer to use the natures of the signs for prognostications or, if we use them, to be in error" I. Retrieved 24 November Nearly 2, years have passed since Ptolemy wrote his Tetrabiblos so the displacement is now approximating to the distance of a whole zodiac sign.
The full cycle completes over the course of 26, years - see Evans p. Generally, other ancient authors referred to all four as tropical, to distinguish them from the 'solid' signs Taurus, Leo, Scorpio and Aquarius which indicate established seasons, and the 'bi-corporeal' signs Gemini, Virgo, Sagittarius and Pisces , which Ptolemy says are so called because "they share, as it were, at end and beginning, the natural properties of the two states of weather" I. For the Sun turns when he is at the beginning of these signs and reverses his latitudinal progress, causing summer in Cancer and winter in Capricorn".
His argument is that such manufactured numerical divisions have no basis in the natural astronomical cycles. Dorotheus begins, not with a proof of the validity of astrology or a description of the universe, but with instructions for calculating births, the native's status, the native's parents status, his brothers, and so on".
I how oaths of silence were required by Orpheus , Pythagoras , Plato and Porphyry. Vettius Valens declared that his teachings should not be imparted to the ignorant or through chance encounters Anthology The 'parts closer to the centre' are then marked off by lines joining the ends of the two latter, dividing each quadrant and producing 4 right-angled triangles at the centre". Robbins p. These groups are later known as the fire, earth, air and water signs, but Ptolemy does not refer to them this way.

Virgo and Capricorn ; and the south-western Ancient Libya , which corresponds to Northwest Africa , to the triplicity of Cancer including Scorpio and Pisces. The planetary stations are where each planet's motion, according to geocentric observation, appears to halt and change direction. This leads the planet into or out of a period of apparent retrograde motion. See also II. Attention is given to significant planetary conjunctions which fall upon, or make aspects to, the zodiac position in which the eclipse occurred.
For an eclipse to be visible and therefore astrologically relevant, it must occur above the horizon, either preceding or succeeding the midheaven. If it falls between the ascendant and the midheaven, then the relevant preceding angle is the ascendant. If it falls between the midheaven and the descendant, then the relevant preceding angle is the midheaven. Preference is given to the planet which holds dominance over the eclipse degree but if the planet that governs the preceding angle is also powerful, preference is given to whichever is closest to one of the angles of the chart.
If it is impossible to distinguish between them, both are used as partners in the signification of effect.

Particular attention is given to the star that rises on the ascendant or culminates on the midheaven, whichever of these is the relevant preceding angle. If the event involves the tropical signs of the zodiac, the effects could be related to politics, whereas fixed signs indicate foundations and constructions of buildings, whilst common signs indicate men and kings. If the animal signs are involved, the effects relate to herds or oxen, but if the sign or constellation presents the form of water or fish, the influence connects to the sea, fleets and floods.
Of the 'terrestrial' signs those depicted by humans or animals that live on land , the northern signs anticipate problems such as earthquakes that arise from the land, whilst the southern signs bring unexpected rains II. If the characteristic colour appears to cover the whole body of the luminary or the whole region surrounding it, the predicted event will affect most of the parts of the countries; but if it is in any one part, it will affect only that part against which the phenomenon is inclined".
This explanation was mirrored in subsequent discussions on why the moment of birth is more reliable, though not separate, from the moment of conception. For example, Johannes Kepler was following Ptolemy when he wrote in his Tertius Interveniens : "When a human being's life is first ignited, when he now has his own life, and can no longer remain in the womb - then he receives a character and an imprint of all the celestial configurations or the images of the rays intersecting on earth , and retains them unto his grave".

Translated by C. The unknown author of the 'Address' in the Elzevir edition reports that it "was translated a few years ago" and says of its author Allatius: "He He undertook his present work, however, for his own private gratification, and that of certain friends; but when writings compiled with this view have once quitted their author's hands, it will often happen that they have also, at the same time, escaped his control. I regret very much that my own work on the present text and translation could not have profited from the results of the textual studies of these two scholars".
