Fī al-falak wa-al-handasah wa-al-ḥisāb

Collection of treatises, copied in the same hand, on mathematical sciences. Topics include calculating heights, distances, areas, solving geometrical and algebraic problems, music theory. At the back of the work are three additions: 1) pages of notes, probably by the copyist, about some of the works in the collection (f. 129r-137v), 2) an added commentary on Apollonius' Conics copied in a different hand (f. 139v-143r), 3) further notes. One folio in Persian (f. 71) is misplaced and should follow folio 78.
