s. XIII2 (after 1264, date of the treatise of Guillaume des Moustiers, f. 110r-113v, and probably before 1293).
Or.:probably Paris (cf. f. 95ra-95va; the attribution of the De utilitatibus astrolabii to Gilebertus, f. 79va, otherwise occurs uniquely in one of Richard of Fournival’s MSS, Paris, BnF, lat. 16652, f. 14v; the MS clearly belongs to a university milieu).
Prov.:the MS belonged to an astrologer active between 1293 and 1310, one of whose clients was a countess Johanna (cf. added notes and horoscopes f. 108r-108v, 109v and 132va).
Parchment, 135 f., at least two hands, one of which copied f. 1-113 (except added notes f. 108r-108v, 109v, 132va), painted initial f. 1r, decorated initials. One or several folia appear to be missing between f. 94 and 95 and after f. 135.

Note Guillaume des Moustiers’s text (f. 110r-113v) has the same incipit as the collection of excerpts from the Almagesti minor (C.1.4) found in several MSS, but it really is a distinct text, even though it draws heavily on Almagesti minor, V.1. See H. Zepeda, The First Latin Treatise on Ptolemy’s Astronomy: The Almagesti minor (c. 1200), Turnhout, 2018, 84-85; and C. P. E. Nothaft, ‘Guillaume des Moustiers’ Treatise on the Armillary Instrument (1264) and the Practice of Astronomical Observation in Medieval Europe’, Annals of Science 78 (2021), 401-417.

‘Translatio Roberti Cestrensis [title added above the line by another hand]. Incipit in nomine Dei pii et misericordis liber [added above the line: Tolomei] de compositione universalis astrolabii. Ptolomeus igitur Mercurii incedens vestigiis in libro suo qui vocatur Almagesti de motu sic ait: Ait enim omnis motus aut de puncto aut ad punctum — cum una eademque utrique conveniat ad plenum dicetur.
