Excerpta ex Quadripartito Ptholomei
A collection of excerpts from the Quadripartitum, with Haly Abenrudian’s commentary, in Egidius de Tebaldis’s translation (C.2.2). These excerpts were assembled by Lorenzo Bonincontri, probably when he was lecturing on astrology at the University of Florence (1475-1478). At least, the Florence MS was copied in Florence and also includes Bonincontri’s commentary on the Centiloquium (C.3.14), whose copy is dated 10 May 1477. The Paris MS was also copied in Florence and appears to be the personal notebook of the astronomer and astrologer Francesco Sirigatti, which includes a section dated 1492 and additions in his hand until 1506. In this manuscript, the text is attributed not to Bonincontri, but to Sirigatti himself (‘Abreviatio Francisci Sirigatti super Quadripartito Ptholomei’) and the two references to Bonincontri found in the title and in the explicit of Book I in the Florence MS (f. 62r and 71v) have disappeared. What is more, in the Paris MS, we find traces of erasure in these two places (f. 1r and 16v), as well as in the final explicit (f. 66r). This suggests that Francesco Sirigatti attempted to appropriate the text for himself.
