20ra‑21va

‘<E>quator diei est circulus maior qui describitur super duos polos orbis ― aut propinqui oppositioni erunt retrogradi. Expletus est liber Thebit filii Chore de his que indigent exposicione antequam legatur Almagesti.’

142ra‑152va

‘Liber Ptho<lome>i expositus Abugafare in quo sunt 100 verba. Dixit Ptho<lomeu>s: Iam premisi libros in quibus tractavi de impressionibus planetarum in hoc mundo composito… Dixit P<tholomeus>: Sciencia astrorum ex te et illis, nec convenit peritum… Quod dixit P<tholomeus>, ex te et illis, significat quod qui res futuras prescire — acciditque in Egypto tunc quidquid dixit Pth<olomeu>s. Hoc est quod ego malui exponi in hoc libro et perfecta est eius expositio.’
