Erfurt Commentary on the Almagest


‘(ed. Zepeda, The Medieval Latin Transmission) 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.’


A commentary on and a reworking of Almagest I.9-II.11 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 Dijon, BM, 441 contains an expanded version, including a preface and a continuation for Almagest, II.12-13, which is probably the work of Jean Fusoris. In MS Erfurt, UFB, Amplon. F. 375, the text is followed (f. 127r-129v), by a super-commentary on it (C.1.10).


Unknown. The text was written no later than the second half of the 14th c. (date of all MSS) and perhaps before 1366 if the assumed dating of MS Vatican, BAV, Pal. lat. 1380 is correct. The origin and content of the four extant MSS point to France and perhaps Paris.
