‘(37r) [preface] Nuper quosdam offendi commentarios in magnam Claudii Ptolemaei compositionem inclito ac Christianissimo Pannoniarum regi Matthiae autore Georgio Trapezuntio inscriptos, quorum ingenti magnitudine subitaque novitate mirum in modum letabar, talis iamdiu cupieris expectans muneris, multo autem maximum videndi desiderium ardorem instinxit maiestas principis cui opus illud dedicatum erat. Non enim nisi elegantissimo quolibet atque optimo — (39r) ab iniuriis distat abstinere siquando alieno indire peccata sua recognoverit. (2r) Defensio Theonis contra Trapezuntium (title in upper margin). [chapter 1] In prefatione Leonem Judeum carpens inquit: Nec potuit percipere dispositiones aeris propinquitatem et remotionem in visu plurimum immutare. Propinquiora enim apparent que humido crassoque medio cernimus — clientulo indicatam tuo declinare velis. Hinc procul fugite quicumque sideralem queritis disciplinam commentariosque mendaces una cum autore suo Georgio Trapezuntio sinite valere.’
