Centiloquium (tr. George of Trebizond)

Text ‘(Basel, UB, O.III.30) [preface] Liber Claudii Ptholomei qui vocatur fructus ad illustrissimum Alfonsum regem Aragonum et utriusque Siciliae a Georgio Trapenzuntio ex Graeco in Latinum versus. Librum Claudii Ptolomei mihi Alfonse rex inclyte traductum quem vulgo Centiloquium ipse fructum appellat — (5v) et quod nec Ptolomeus sentit nec apparentia nonum ponere orbem cogere videntur. (6r) [text] Liber Claudii Ptolomei qui vocatur fructus ad illustrissimum Alfonsum regem Aragonum et utriusque Siciliae a Georgio Trapenzuntio ex Greco in Latinum versus. Iam pridem perutiles ad previdendum operationes stellarum, o Syre, quas in hoc composito efficiunt mundo exposuimus… Primus aphorismus. Abs te et a scientia, non est enim possibile ut huius scientiae professor particulares rerum ideas prevideat — (14v) Sin vero non moventur hostis indigena erit. Finis. (15r) [comm.] Commentarii et expositiones Georgii Trapezuntii in aphorismis libri fructus Ptolomei ad Alfonsum regem Aragonum et utriusque Sicilie. Libellus hic quem de Graeco traductum nomini tuo dedicavimus, illustrissime rex… (16v) Abs te et a scientia. Abs te, inquit, hoc est a quadam insita vi animi et ingenio et a scientia nature stellarum precognitio fit — ut sicut raro apparent, sic inconsueta significare videantur.’
