An anonymous commentary on the Almagesti minor (C.1.4) consisting of ‘a mixture of excerpts, summaries, and commentary’ (Zepeda, 118). The text appears to be incomplete or unfinished in the only known manuscript. This commentary was composed after c. 1462, since the author used Regiomontanus’s Epitome Almagesti (C.1.21), and may have originated with the scribe/author of the manuscript c. 1500. An alternative title of the work is given to Book III: ‘Incipit liber tertius epythomatis super astronomia Albategni’.

Text ‘(Utrecht, UB, 6.A.3) Incipit liber Almagesti Ptholomei abbreviatus. Prefatio sex continens conclusiones. Omnium recte phylozophantium non solum verissimilibus et credibilibus argumentis — de duobus reliquis triangulis orthogoniis duarum.’
