In a manuscript of the Cotton collection in the British Museum is a work of some length upon astrology ascribed to Aristotle.[794] After a discussion of general principles in which the planets, signs, and houses are treated, there are separate books upon the subjects of nativities,[795] and of elections and interrogations.[796] In a Paris manuscript a treatise on interrogations is ascribed in a marginal heading to “Aristoteles Milesius, a Peripatetic physician.”[797] In the Cotton Manuscript in commentaries which then follow, and which are labelled as commentaries “upon the preceding treatise” Ptolemy is mentioned rather than Aristotle.[798] In an astrological manuscript of the fifteenth century at Grenoble written in French, works of Messahala and Zaël translated for Charles V of France are preceded by “a book of judicial astrology according to Aristotle,” which opens with “the preface of the last translator,” and is in four parts.[799] Perhaps both the above-mentioned manuscripts contain, like a third manuscript at Munich, “The book of judgments which is said by Albert in his Speculum to be Aristotle’s.”[800] This work also occurs in a manuscript at Erfurt.[801] Roger Bacon was much impressed by an astrological treatise ascribed to Aristotle entitled De impressionibus coelestibus, and told Pope Clement IV that it was “superior to the entire philosophy of the Latins and can be translated by your order.”[802]
Aristotle and two hundred and fifty volumes of the Indians.
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.
Works on astrological images.
The Secret of Secrets of the Pseudo-Aristotle is immediately followed in one manuscript by chapters or treatises addressed to Alexander and entitled, Of ideas and forms, Of the impression of forms, and Of images and rings.[807] The theory, very like that of Alkindi, is maintained that “all forms are ruled by supercelestial forms through the spirits of the spheres” and that incantations and images receive their force from the spheres. The seven planets pass on these supercelestial ideas and forms to our inferior world. By selecting proper times for operating one can work good or ill by means of the rays and impressions of the planets. The scientific investigator who properly concentrates and fixes intent, desire, and appetite upon the desired goal can penetrate hidden secrets of secrets and occult science both universal and particular. The writer goes on to emphasize the importance of understanding all the different positions and relationships of the heavenly bodies and also the distribution of terrestrial objects under the planets. He then describes an astrological image which will cause men to reverence and obey you, will repel your enemies in terror, afflict the envious, send visions, and perform other marvelous and stupefying feats too numerous to mention.
And on necromantic images.
As the Speculum astronomiae of Albertus Magnus listed a Book of Judgments by Aristotle among deserving works of astronomy and astrology, so in its list of evil books dealing with necromantic images appear a treatise by Hermes addressed to Aristotle and opening, “Aristotle said, ‘You have seen me, O Hermes,’” and a treatise ascribed to Aristotle with the sinister title, Death of the Soul, opening, “Said Aristotle to King Alexander, ‘If you want to perceive.’” This treatise the Speculum calls “the worst of all” the evil books on images. Roger Bacon, too, alludes to it by title as filled with figments of the magicians, but does not name Aristotle as author.[808] Peter of Abano in his Lucidator follows the Speculum astronomiae in listing it among depraved, obscene, and detestable works.[809]
Alexander as an astrologer.
Alexander himself, as well as Aristotle, had some medieval reputation as an astrologer. We have already seen[810] in the tenth and eleventh century manuscripts of the Mathematica of Alhandreus, supreme astrologer, that “Alexander of Macedon” was more than once cited as an authority, and that there were also given “Excerpts from the books of Alexander, astrologer, king,” and a “Letter of Argafalan to Alexander.” Different from this, moreover, was the Mathematica of Alexander, supreme astrologer, found in a thirteenth century manuscript, in which from the movements of the planets through the signs one is instructed how to foretell prosperous and adverse journeys, abundance and poverty, misfortune or death of a friend, or to discover stolen articles, sorceries, buried treasure and so forth.[811] A treatise on seven herbs related to the seven planets is sometimes ascribed to Alexander,[812] but perhaps more often to Flaccus Africanus, as we saw in Chapter 46, and at least once to Aristotle.[813]
