‘Laurentii Bonincontri Miniatensis super Centiloquio Ptolomei. Astrologiam esse omnium liberalium artium excellentissimam, nemo est qui ignoret tum propter ipsius scientie nobilitatem… (24v) Scientia stellarum ex te et illis est, hoc est ut sis homo bone vite — a signis celi nolite metuere. Deo igitur laus, honor et glora per infinita secula seculorum. Amen. Laurentii Bonincontri Miniatensis commentum super Centiloquio Ptholomei feliciter explicit. Transcriptum per me Laurentium Silvestri canonicum ecclesie Sancti Laurentii Flor<entie> die X Maii 1477, hora 22 ½ .’

‘Exerpta per me Laurentium Bonincontrum Miniatensem ex Quadripartito Ptholomei et expositione Hali commentatoris sive Porphiri. Ex capitulo primo commenti. <S>cientia stellarum est ars a principiis certis aliarum scientiarum proveniens, quibus ea que accidunt possunt sciri cuius principia in phisicis… Ex textu et commento de pronosticandi scientia. Duas esse res quibus pronosticandi scientia perficitur et has maiores aliis quia de omnibus rebus potest cognoscere astrologus — et extrahemus a locis mensium et dabimus cuilibet signo duos dies et tertium. Finis. Deo gratias.’
