He returned to the camp at Santa Fe, and on April 17, 1492, the agreement between him and their Catholic Majesties was signed and sealed. This agreement being familiarly known in Spanish history as "The Capitulations of Santa Fe." His aims were nothing less than the discovery of the marvelous province of Cipango and the conversion to Christianity of the Grand Khan, to whom he received a royal and curious blank letter of introduction. The town of Palos was, by forced levy, as a punishment for former rebellion, ordered to find him three caravels, and these were soon placed at his disposal. But no crews could be got together, Columbus even offering to throw open the jails and take all criminals and broken men who would serve on the expedition; and had not Juan Perez succeeded in interesting Martin Alonzo Pinzon and Vicente Yanez Pinzon in the cause, Columbus' departure had been long delayed. At last, however, men, ships, and stores were ready. The expedition consisted of the Gallega, rechristened the Santa Maria, a decked ship, with a crew of fifty men, commanded by the Admiral in person; and of two caravels--the Pinta, with thirty men, under Martin Pinzon, and the Nina, with twenty-four men, under his brother, Vicente Yanez Pinzon, afterward (1499) the first to cross the line in the American Atlantic. The adventurers numbered 120 souls, and on Friday, August 3, 1492, at 8 in the morning, the little fleet weighed anchor and stood out for the Canary Islands, sailing as it were "into a world unknown--the corner-stone of a nation." Deeply significant was one incident of their first few days' sail. Emilio Castelar tells us that these barks, laden with bright promises for the future, were sighted by other ships, laden with the hatreds and rancors of the past, for it chanced that one of the last vessels transporting into exile the Jews, expelled from Spain by the religious intolerance of which the recently created and odious Tribunal of the Faith was the embodiment, passed by the little fleet bound in search of another world, where creation should be newborn, a haven be afforded to the quickening principle of human liberty, and a temple be reared to the God of enfranchised and redeemed consciences.
