Hundred sayings of astrology

The Centiloquium (= "one hundred sayings"), also called Ptolemy's Centiloquium, is a collection of one hundred aphorisms about astrology and astrological rules. It is first recorded at the start of the tenth century CE, when a commentary was written on it by the Egyptian mathematician Ahmad ibn Yusuf al Misri (later sometimes confounded with his namesake Ali ibn Ridwan ibn Ali ibn Ja'far al Misri, or in Latin "Haly ibn Rodoan", who lived a century later and wrote a commentary on Ptolemy's Tetrabiblios).

The Centiloquium opens with a dedication to Syrus, like the classical astronomer Ptolemy's astrological treatise the Tetrabiblos ("Four books"). Ptolemy was indeed accepted as its author by medieval Arabic, Hebrew and Latin scholars, and the book was widely taken up and quoted. In Arabic it was known as the Kitab al Tamara ("Book of the Fruit"), the name supposedly a translation of the Greek [[Karpos meaning "fruit", the book's aphorisms being seen as standing as the fruit or summation of the earlier treatise. It was translated at least four times into Latin, in which it was also known as the Liber Fructus, including by John of Seville in Toledo in 1136 and by Plato of Tivoli in Barcelona in 1138 (printed in Venice in 1493). In Hebrew it was translated at the same time by Tivoli's collaborator Abraham bar Hiyya, and again in 1314 by Kalonymus ben Kalonymus, as the Sefer ha Peri ("Book of the fruit") or Sefer ha Ilan ("Book of the tree"). Regardless of its authorship, the text has been described as "one of the most influential texts in astrology's history". It was, for example, a standard set text for medical students at the University of Bologna in the fifteenth century. However, as even the original commentary on the book noted, the Centiloquium contains quite substantial differences in focus from the Tetrabiblos: for example, it is very concerned with "Interrogations", the asking of astrological questions about forthcoming plans and events, which is not treated at all in the earlier work. In the 1550s the Italian scholar Cardano considered this, and pronounced the work to be pseudoepigraphic – not by Ptolemy at all. This has also tended to be the view of subsequent centuries. For example, aphorism 63 discusses implications of a conjunction of Jupiter and Saturn; but this is a doctrine developed by Arabic astrologers, not known to the Greeks.

A Latin text containing one hundred propositions, again about astrology rather than Hermeticism, compiled by Stephen of Messina at a date between 1258 and 1266 for Manfred, King of Sicily, supposedly either from a variety of Arabic sources or from an unknown Arabic original.

One hundred astrological propositions ascribed to Muhammad ibn Jabir al Battani (c.858–929), also known as Albategnius, or in astrology as Bethem. The text also exists in many manuscripts as De consuetudinibus ("According to the customs"), ascribed to Abraham ibn Ezra (1089–1164).
