Abstract

This article, divided into three parts, presents manuscript identifications from the fifteenth-century Paris Arts Faculty. The first case concerns manuscripts previously thought to transmit a commentary on Summule logicales by Peter of Spain, attributed to the Parisian master Guillelmus de Curis: direct inspection revealed that these manuscripts actually contain the commentary on the same text by Johannes Versoris, suggesting that Guillelmus de Curis’s commentary is likely a bibliographical ghost. The second part examines an anonymous codex containing commentaries on natural philosophy, traditionally ascribed to Petrus Tartaretus, which my research has attributed to Johannes Damoisiau. Finally, the third part reports the identification of two manuscripts transmitting commentaries on natural philosophy by Johannes de Caulaincourt (de Magistris).
