‘Comentator libri centum verborum Ph<tolome>i qui dicitur Hally philosophus. Dixit Pth<olome>us: Iam scripsi tibi, Iesure, libros de hoc quod operantur stellae in hoc seculo… Hic docetur quomodo astro<logus> iudicare debeat… Glosa. Scientia stellarum dividitur in duo, in astrologiam et astronomiam, quarum utraque habet suam teoricam et suam practicam… (11v) Expositio primi verbi. Quod dixit Pth<olome>us, ex te et illis est, significat quod qui res futuras prenoscere desiderat — Et ego Deum deprecor ut te diligat. Perfecta est huius libri translatio 17 die mensis Marcii, 12 die mensis Gumedi secundi anno Arabum 5202 (!). Deo gracias. Amen. Explicit liber 100 verborum Pth<olome>i sive Centiloquii cum comento Hally philosophi.’
