Cambridge, University Library, Ii 1.13 (1705)

s. XIV1 (the date 1279, given in the colophon of the first Ptolemaic section, is in all likelihood the date of the exemplar, for this section is written in the hand that copied most of the MS, including Richard of Wallingford’s Quadripartitum (f. 64r-77r), a work composed not long before 1326).


England. This MS seems to be the unique copy of the works of Walter Odington, monk of Evesham, contained on f. 44v-56v and 160r-181r (on these works, see North).


‘Possessor mei Anthonius Rous’ (f. 2r, 16th c.); ‘Symond Ockey off Hyngham’ (f. 202r, 17th c.); W. Crow, of Caius College, who gave the MS to the University of Cambridge in 1656 (North).

Parchment, 204 f. (various competing foliations – I use what seems to be the latest one, which differs from the one used by the Catalogue), one main hand, including for the first Ptolemaic section, with intervention of several contemporary hands in various places, including for the second Ptolemaic section.
