A treatise found in two manuscripts of the Bodleian Library bears the titles, _Commentary of Aristotle on Astrology_, and _The book of Aristotle from two hundred and fifty-five volumes of the Indians, containing a digest of all problems, whether pertaining to the sphere or to genethlialogy_.[803] From the text itself and the preface of Hugo Sanctelliensis, the twelfth century translator from Arabic into Latin, addressed to his lord, Michael, bishop of Tarazona, we see that the work is neither entirely by Aristotle nor from the books of the Indians but is a compilation by someone who draws or pretends to draw from some 250 or 255 books[804] of the philosophers, including in addition to treatises by both Aristotle and the Indians, 13 books by Hermes, 13 by Doronius (Dorotheus?), 4 by Ptolemy, one by Democritus, two by Plato, 44 by the Babylonians, 7 by Antiochus, and others by authors whose names are unfamiliar to me and probably misspelled in the manuscripts. In one of the works of Aristotle of which the present work is supposed to make use, there are said to have been described the nativities of twelve thousand men, collected in an effort to establish an experimental basis for astrology.[805] It is not so surprising that the present work bears Aristotle’s name, since Hugh had promised his patron Michael, in the prologue to his translation of the _Geometry_ of Hanus ben Hanne,[806] that if life endured and opportunity was given he would next set to work as ordered by his patron, not only upon Haly’s commentaries on the _Quadripartite_ and _Almagest_ of Ptolemy, but also upon a certain general commentary by Aristotle on the entire art of astrology.
