Commentary on Pseudo-Ptolemy's Iudicia

Text ‘(London, BL, Cotton Appendix VI ) Incipit commentum super premissa, scilicet predictum librum. [preface] Artem artium, scilicet astronomiam, aggredientibus dicendum est primo quid sit ipsa differentie (?), quid sit eius genus, que eius materia… (23vb) [text] Expositio ad litteram superioris tractatus. Ptolomeus summus philosophus et excellentissimus Egyptorum rex necnon fide unitatis minutas (?) filium unius instruens Aristonem cuius causa hoc opus incepit ad litteram huius artis accedens hanc divisionem facit. Signorum alia sunt masculina et alia feminina etc. Hoc vero divisio potest vocari naturalis et artificialis — tam bonas quam malas querat. Hic terminatur astronomia Aristotelis cum expositione eius.’

Content A commentary on Pseudo-Ptolemy’s Iudicia (B.9).

Origin This anonymous commentary was composed c. 1138. In MS London, BL, Cott. App. VI, the text immediately follows Pseudo-Ptolemy’s Iudicia (f. 8rb-20va), here attributed to Aristotle (‘Liber iste est Aristotelis in scientia ipsius astronomie’, f. 8rb), which explains the attribution in the explicit of the commentary. The date 1138 is given as example for an astronomical calculation (f. 21va). In St Petersburg, BAN, F. 8, the text follows Hermann of Carinthia’s De occultis (155ra-169vb) and further chapters on interrogations (170ra-171va). Hermann of Carinthia, who was active in 1138, is a possible candidate for the authorship.
