‘Incipit liber fructuum arboris Ptolomei a magistro Iohanne Toletano translatus ab Arabico in Latinum, continens 100 sermones et dicatur Centiloquium. Scientia stellarum ex te et illis est. Astrologus non debet dicere rem specialiter sed universaliter… <D>ixit Ptolo<meus>: Iam scripsi tibi, Iesure, id est domine, libros tractantes de hoc quod operantur stelle in hoc seculo… Quod dixit Ptolo<meus>, ex te et illis, significat quod qui res futuras desiderat prescire — Et ego Deum deprecor ut te dirigat. Et perfecta est huius libri translatio 3a die mensis Martii, 2a die Gunedi secundi, anni Arabum 309. Deo gratias et eius pie matris.’
