Commentum super Almagesti
A commentary on Almagest I-III, written by Simon Bredon in Oxford probably c. 1340. The author used Gerard of Cremona’s translation of the Almagest (A.1.2) and the Almagesti minor (C.1.4). None of the three extant manuscripts is complete and it is unclear whether a fuller commentary once existed. MS Oxford, BL, Digby 168 is Simon’s autograph, but this copy is truncated, missing I.3-12 (due to three lost folia) and the first chapters of Book II (due to two lost folia). MS Oxford, BL, Digby 178 opens with I.9 and MS Cambridge, UL, Ee 3.61 (1017) only preserves an excerpt from Book I.
