Work B.12

Pseudo-Ptolemy
Iudicia

Text

‘(Paris, BnF, lat. 16208) Iudiciorum Ptolomei ad Aristonem filium suum liber incipit. Signorum alia sunt masculini generis, alia sunt feminini, scilicet ut Taurus, Cancer — neque amici neque inimici sunt ad invicem.’

Content

A text in two parts (two books in Aristotle’s version), comprising (1) theoretical chapters on the planets and the signs of the zodiac, and (2) a collection of iudicia consisting mainly of interrogations based on the position of the ruler of the ascendant in the twelve houses and on the planetary hours.

Origin

This text exists in two versions, one attributed to Ptolemy, the other to Aristotle, both of which seem to derive from a common, lost source which was probably translated or adapted from Arabic. Ptolemy’s version was used by Raymond of Marseilles in his Liber iudiciorum (1141) and gave rise to an anonymous commentary in which the year 1138 is taken as an example of astronomical calculation (C.4.6). The text – or the common source – may be as old as the tenth century for it shares characteristics in style and content, including several identical chapters, with the Alchandreana. The text is said to have been addressed by Ptolemy to his son ‘Aristo(n)’ (Aristotle’s version is said to have been addressed to king ‘Alco(n)’). The manuscripts listed below are those of Ptolemy’s version only. Aristotle’s version is extant in some 15 manuscripts, three of which attribute the text to Ptolemy: Madrid, BN, 10009, s. XIII, f. 109ra-117vb (‘Incipit Ptholomei liber… Explicit hic liber qui dicitur Tholomei’); Wolfenbüttel, HAB, 51.9 Aug. 4° (3549), s. XIII, f. 69r-91r (‘Hunc tractatum edidit Ptolomeus unus de regibus Egipti, nec est idem Ptolomeus qui edidit Almagestum vel Quadripartitum sed diversus’, added note at f. 69r); and Catania, BU, 87, s. XV, f. 89ra-101va (‘Incipit Ptholomei liber’). A reworking of the text is extant in Bernkastel-Kues, CSB, 209, and is possibly the work of Bartholomew of Parma (see C. Burnett, ‘Partim de suo et partim de alieno: Bartholomew of Parma, the Astrological Texts in MS Bernkastel-Kues, Hospitalsbibliothek 209, and Michael Scot’, in Seventh Centenary of the Teaching of Astronomy in Bologna, 1297-1997, eds P. Battistini, et al., Bologna, 2001, 37-76: 51-57).
