17 works, chiefly Arabic translations of Greek treatises and responses to them concerning geometry and astronomy, given a collective title that signifies that these works were to be read after Euclid's Elements in preparation for Ptolemy's Almagest (note on flyleaf 3r, at front of book). Four works (12, 13, 16, 17) are not translations, one (9) is qualified as revised by al-Kindī, one (16) is copied in a different style, and one (17) is on music. A table of contents is included (flyleaf 1 verso, at front of book), and the colophon of work 15 (f. 160v) says that Kitāb al-mutawassiṭāt is complete before listing the next two works that will follow. 1 online resource (180 foliated leaves) : paper, illustrations
