‘Dixit Ptolomeus: Iam scripsi sunt tibi, Iesure, libros de hoc quod operantur stelle in hoc seculo… Scientia stellarum et ex te et illis est… <Q>uod dixit Ptolomeus, ex te et aliis (!), significat quod qui res futuras cognoscere desiderat — Et ego Deum precor ut te diligat. Et perfecta est huius libri translatio 17 die mensis Marcii, 12 die mensis Gumudi (?) secundi anno Arabum 5302 (!).’
