Erfurt Commentary on the Almagest I

Text  ‘(ed. Zepeda) Data circuli dyametro latera decagoni, pentagoni, hexagoni, tetragoni et trianguli omni ab eodem circulo circumscriptorum reperire — de aliis signis in quolibet climate etc. Et sic est expleta dictio secunda Almagesti.’

Content A commentary and reworking on sections I.9-II.11 (with additions for II.12-13 in Dijon, BM, 441) of the Almagest arranged by propositions and proofs. Enunciations are close to those of the Almagesti minor (C.1.3), but the rest of the text differs. MS Erfurt, UFB, Amplon. F. 375 might be the autograph. In this MS, the text is followed, on f. 127r-129v, by another, closely related commentary (Erfurt Commentary II).

Origin Unknown. The commentary was written in the second half of the 14th c. at the latest.
