Conrad Heingarter
Commentary on the Centiloquium

Text

‘(Paris, BnF, lat. 7432) [text] Incipit Centilogium Ptholomei. Prologus Haly. Dixit Ptholomeus: Iam scripsi tibi, Iesure, libros de hoc quod operantur stelle… Propositio prima: Mundanorum mutatio ad hoc et ad illud corporum supercelestium… (135r) [conrad heingarter’s comm.] <V>etus oppinio est (ut dicit Cicero) iam usque ab heroicis ducta temporibus eaque et veteris populi Romani et omnium gentium firmata — (146r) [text] si vero fuerint immobiles, erit proditor ex aliqua civitatum eiusdem climatis. [conrad heingarter’s comm.] … Et inveni quemdam parvum tractatum de speciebus cometum seu cometarum qui Ptho<lome>o ascribitur, eumque adiunximus in fine verbis Ptholomei, eumque glosavimus ut sequitur. (146v) [text] Ptholomeus dixit quod stelle cum caudis sunt novem… [conrad heingarter’s comm.] <D>ixit Ptholemeus: Stelle cum caudis sunt novem etc. Loquamur nunc in speciali de cometibus — (151r) [text] in regibus et divitibus apparebit. [conrad heingarter’s comm.] … quoque distanciis ad presens sufficiant.’

Content

A commentary on the Centiloquium in Plato of Tivoli’s translation, including Pseudo-Ptolemy’s De cometis (B.4) at the end. The exact nature of Conrad’s contribution remains to be investigated, as in the case of his commentary on the Quadripartitum (C.2.9).

Origin

Composed by Conrad Heingarter for the Duke of Bourbon Jean II in 1477 (cf. f. 148v: ‘finita fuerunt hec commentaria in Bellapartica tertio die Ianuarii anno 1477° currente’).
