upon which we are born and live, that it is placed within the sphere of the heavens, that it does not in any part touch them, or any other firm substance, by which it is supported, but land and water are encircled round about by the void space of the heavens. He likewise ascertained in what way land abounding in gold might be discovered, and that, since this earth, or terraqueous globe, may be passed entirely around, by land and by water, (as John de Mandeville relates,) whoever should have suitable vessels, and should pursue the right course, by sea and land, might sail directly west from Cape St. Vincent, and return by way of Jerusalem and Rome to Seville; which would be to go completely round the circumference of the whole earth. Also, he constructed a map of the world, to which he devoted much study, and thus perceived that, in whatever direction one should sail across the ocean, he could not avoid finding land; and moreover he satisfied himself as to the route, by which a region of much gold might be discovered; a favorite subject of his thoughts.
Knowing that King John, of Portugal, was much interested in discovery, he offered his services to that monarch; but his theory being stated, no credit was given to it, because the Portuguese King had in his service many eminent and learned navigators, who made light of it, and took for granted that there were in the world no other discoverers greater than themselves. So Columbus came to the court of King Ferdinand and Queen Isabella, and explained to them his theory; to which they likewise gave but little credit: but he conversed with them, and assured them that what he said was certainly true, and showed them his map of the world, till he excited in them a desire to know something about those countries, of which he told them. And having dismissed him, they summoned their astrologers, astronomers, and courtiers who were learned in cosmography, whose advice they required; and the opinion of the majority of them, after hearing Columbus, was that his views were correct. Accordingly, the King and Queen concluded an agreement with him, ordered three vessels to be fitted out at Seville, with men and provisions, within the time that he desired, and despatched him, in the name of God and our Lady, upon his discoveries.
