8r‑70r, 76v‑77r

‘Incipit liber 4 tractatuum Ptolomei Alfilludhi in scientia iudiciorum astrorum et in primo tractatu sunt 24 capitula. Capitulum primum in collatione intellectus scientie iudiciorum astrorum. Rerum, Yesure, in quibus est pronosticabilis scientie stellarum profectio magnas et precipuas duas esse deprehendimus — (70r) hoc in loco huic libro finem inponere non incongruum existimamus. Explicit liber 4 Quadripartiti. (76v) Capitulum X in fortitudinibus quatuor temporum. Stellarum itaque fortitudinum qualitates in semetipsis ut ab antiquis expertum est sunt hee — et alii etiam 30 gradus punctum hyemalis solstitii ordinatim succedentes.’

= Ptolemy, Quadripartitum (tr. Plato of Tivoli) (A.2.1). I, 8r-22r; II, 22r-36r; III, 36r-56v; IV, 56v-70r; I.10-12, 76v-77r. The scribe copied chapters I.10-11 and the first lines of I.12 on f. 76v-77r because he had accidentally skipped that section in the text supra (cf. f. 15v: ‘[I.10] Capitulum 10 in fortitudinibus 4 temporum. Stellarum itaque fortitudinum qualitates in semetipsis ut ab antiquis expertum est [I.12] solstitii ordinatim succedentes, qui sunt Capricorni gradus’). Short marginal notes by the scribe f. 20r-21r.

70r‑70v

‘Incipit scientia proiectionis radiorum. Cum proiectionem radiorum stellarum scire volueris, scias gradum ascendentis — erit locus radiationis equate. (70v) Explicit Quadripartitus Ptholomei.’

= Pseudo-Ptolemy, Liber proiectionis radiorum stellarum (B.18), apparently considered part of the Quadripartitum (but see explicit above, f. 70r). One short marginal note by the scribe f. 70r.

70v‑76r

‘De iudiciis partium et primo de parte fortune, hec accipitur in die a Sole in Lunam, in nocte e contra, et prohicitur ab ascendente. Quoniam et in primo libro partium terminos et loca posuimus, iudicia sub earundem ministrare curavimus. Pars fortune et eius dominus corpus — partis significationem aut eius domini hiis XII duodecim mensibus mutatur.’

137v‑142r

‘Incipit Centiloquium Tolomei. Iam scripsi tibi, Yesuret (?), libros de hoc quod operantur stelle in hoc seculo… I. Scientia stellarum ex te et illis est — ex aliqua civitatum illius climatis. Summi Ptolomei Centiloquium finit.’

171r‑194v

‘Yhesus Christus 1462. Centiloquium Ptolomei cum commento Haly. Mundanorum ad hoc et ad illud mutatio celestium corporum mutatione contingit, rerum igitur causas rimaturus opus est celestia contemplare. Commento (!). Dixit Ptolomeus, mundanorum etc.: Iam scripsi tibi, Yesure, libros de hoc quod operantur stelle in hoc mundo… Primo verbo [title in the margin]. Scientia stellarum ex te et ex illis. Astrologus non debet dicere rem specialiter sed universaliter… Cum dixit Ptolomeus, ex te et ex illis, significat quod qui res futuras cognoscere desiderat — et ego precor Deum ut te diligat. Perfecta est huius libri translacio 3° die mensis Martii, secundo (?) die mensis Iumedi secundo anno Arabum 300. Explicit Centiloquium Ptholomei cum commento Haly.’

= Pseudo-Ptolemy, Centiloquium (tr. Plato of Tivoli) (B.1.2), except the first sentence from the ‘Mundanorum’ version (B.1.4). No glosses.
