An epitome of the Quadripartitum in Plato of Tivoli’s translation (A.2.1) and of Pseudo-Ptolemy’s Liber proiectionis radiorum stellarum (B.6). The only known witness, which may well be the autograph, was copied in northern Italy around the middle of the fourteenth century, perhaps more precisely in or around Padua between 1338 and 1345. Book I opens with a detailed account of c. 9 on the fixed stars, followed by c. 4-8, 10-23 and 2-3 (c. 1 is ignored). The other books present the chapters in regular order.
