A set of notes discussing passages of Theon’s commentary on the first book of the Almagest. In the Pisa MS, these notes follow immediately the translation of the text by George Fleming and Alessandro Marchetti (C.1.30.9) and are perhaps in Marchetti’s hand. They end abruptly at the bottom of f. 99v, leaving no clue as to how many pages may be missing. The extant section discusses two of Theon’s passages from c. 3 and 9 (= c. 4 and 10 in Heiberg’s edition of the Almagest), found on pp. ‘49’ and ‘114’ respectively, i.e. f. 24r and 56v in the current foliation of the manuscript.
