8 CONCEPTIONS OF COLUMBUS 



turn leuche .600., videlicet, 450. ad austrum, et .250. 

 ad aquilonem, usque uno promontorium per ipsum nomi- 

 natum "cabo de Boa Esperanga," quern in Agesinba esti- 

 mamus; quique in eo loco invenit se distare per astrola- 

 bium ultra linea equinociali gradus 45., quern ultimum 

 locum distat ab Ulixbona leuche .3100. quern viagium 

 pictavit & scripsit de leucha in leucha in una carta navi- 

 gacionis, ut occuli visui ostenderet ipso serenissimo regi. 

 in quibus omnibus interfui.^ (Note that this year 88, 

 in the month of December, Bartholomew Dias returned 

 to Lisbon, the captain of three caravels, which the most 

 serene king of Portugal had sent to Guinea to discover 

 land; and he reported to that most serene king that he 

 had sailed 600 leagues beyond the farthest region hitherto 

 navigated, namely 450 to the south and 250 to the east, 

 to a cape named by him "Cabo de Boa Esperanga," 

 which we think is in Agesinba; and by the astrolabe he 

 found himself in that place to be beyond the equator 45 

 degrees, which farthest point is distant from Lisbon 

 3100 leagues. He pictured and wrote down the voyage 

 from league to league in a chart of navigation, that he 

 might show the voyage by eyesight to that most serene 

 king. In all of this I was present.)

Quolibet gradus habet miliaria .562^., et sic habet 

 totus circuitus terre .20400.^ (Each degree has 567^ 

 miles, and thus the whole circumference of the earth is 

 20,400 miles.)
