Vatican, Biblioteca Apostolica Vaticana, Barb. lat. 182

s. XV (perhaps ‘1452’, written in the top margin of f. 1r, but this might not be a date; added horoscope for 17 July 1456 f. 1v).

Or.:

northern Italy, perhaps Florence, see f. 2vb: ‘Magistri Filippi Cēnii (?) de Florentis’, by or in connection with the second hand.

Prov.:

‘Caroli Strozzae Thomae filii 1635’ (f. 3r).

Paper and parchment, 138 f. The MS originally consisted of five texts copied by a neat hand (f. 3r-99r, 103r-124r, 125r-133ra), with painted initial on f. 3r. Later on, a second, rather careless, hand glossed the MS and added numerous texts and notes in the margins of f. 103r-110v and 132r-133r, and on pages which had been left blank (f. 1r-2v, 99v-102v, 124v, 133v-139r). It cannot be ruled out, however, that both hands belong to one and the same scribe, for both sign in a similar fashion, e.g. ‘Omnipotenti gratiarum actiones referendo’ (first hand, f. 99rb) and ‘Deo omnipotenti gratias’ (second hand, f. 100rb).

Astronomy and astrology: the five original texts included Ptolemaica (3ra-99rb); Campanus of Novara, Theorica planetarum (103ra-119va); Theorica planetarum Gerardi (119va-124rb); Haly Embrani, De electionibus horarum (125ra-132ra); Gergis, De significatione septem planetarum in domibus (132rb-133ra). The added texts and notes include, among others, a set of sortes at least partly related to the Prognostica Socratis Basilei (1ra-2v); excerpts from Thebit Bencora’s De imaginibus (99va-99vb) and the Speculum astronomie (100va-101rb); Ptolemaica (101rb-101vb); excerpts from Alcabitius’s Introductorius (102ra-102vb); Alkindi (?), Saturnus in Ariete sub radiis… (132rb-133rb); Astronomia Ypocratis, anonymous tr. (133rb-133vb); Albumasar, Flores (136rb-137rb); Capitula Almansoris (137va-138rb); Zael, Quinquaginta precepta (138rb-138va).

3ra‑99rb

‘Prologus primus in Almagesto Ptholomei Pheludensis. Quidam princeps nomine Albuguafe in libro suo quem scientiarum electionem et verborum nominavit… (3rb) Capitulum primum in quo huius scientie ad alias excellentiam et finis eius utilitatis dicit. Bonum fuit scire quod sapientibus non deviantibus visum est — abbreviationem, arrogantiam et collaudationem, tunc iam sequitur et honestum est ut ponamus hic finem libro. Deo laus. Expleta est dictio XIIIa libri Ptholomei et cum ea completur liber Almagesti de disciplinalibus. Omnipotenti gratiarum actiones referendo.’
