308 APPENDIX. mus. Sub quo tempestatis infortunio quinque navigavimus diebus, demissis omnino velis. In quibus quidem quinque diebus ducentas et quinquaginta in man penetravlmus leucas, lineee interdum equinoc- tiali, necnon mari et aurse temperatlori semper appropinquando, per quod nos a prscmissis eripere periculis altissimo Deo placuit. Eratque hujuscemodi nostra nav'igatio ad transmontanum ventum et Grsecum, ob id quod ad ^thiopise latus pertingere cupiebamus, a quo per maris Atlantici fauces eundo, mille tercentum distabamus leucis. Ad illam autem per summi tonantis gratiam Maij bis quinta pertigimus die. Ubi in plaga una ad latus Austri, quae Serraliona dicitur, quindecim diebus nos ipsos refrigerando fuimus. Et post hsec cursum nostrum versus insulas Lyazori dictas arripuimus : quK quidem insulse a Ser- raliona ipsa septingentis et quinquaginta leucis distabant, ad quas sub Julii finem pervenimus, et pariter quindecim inibi nos reficiendo perstitimus diebus. Post quos inde exivimus, et ad Lisbonse nostrse recursum nos accinximus, a qua ad occidentis partem tercentum sepo- siti leucis eramus, et cujus tandem deinde portum MDII cum pros- pera salvatione et cunctipotentis nutu rursum subi^imus cum duabus duntaxa navibus, ob id quod tertiam in Serraliona, quoniam amplius nangare non posset, ignicombusseramus. In hac autem nostra tertio cursa na^^gatione, sexdecim circiter menses permansimus : e quibus undecim absque transmontanese stellre, necnon et majoris ursse mino- risve aspectu na\-iganmus, quo tempore nosmetipsos per aliam meri- dionalis poli stellam regebamus : quae superius commemorata sunt, qure in eadem nostra teitio facta na^•igatione, relatu magis digna conspexi."
