The vessels then turned southward, following the coast till the 20th, when Ponce landed near Abayoa, a cluster of Indian huts. On attempting to sail again, he met such violent currents that his vessels could make no headway, and were forced to anchor, except one of the caravels, which was driven out of sight. On landing at this point Ponce found the Indians so hostile that he was obliged to repel their attacks by force. He named a river Rio de la Cruz; and, doubling Cape Corrientes on the 8th of May, sailed on till he reached a chain of islands, to which he gave the name of the Martyrs. On one of these he obtained wood and water, and careened a caravel. The Indians were very thievish, endeavoring to steal the anchors or cut the cables, so as to seize the ships. He next discovered and named the Tortugas. After doubling the cape, he ran up the western shore of Florida to a bay, in 27° 30’, which for centuries afterward bore the name of Juan Ponce. There are indications that before he turned back he may have followed the coast till it trended westward. After discovering Bahama he is said to have despatched one caravel from Guanima under John Perez de Ortubia, with Anton de Alaminos, to search for Bimini, while he himself returned to Porto Rico, which he reached September 21. He was soon followed by Ortubia, who, it is said, had been successful in his search for Bimini. Although Ponce de Leon had thus explored the Florida coast, and added greatly to the knowledge of the Bahama group, his discoveries are not noted in the editions of Ptolemy which appeared in the next decade, and which retained the names of the Cantino map. The Ribeiro map (1529) gives the Martyrs and Tortugas, and on the mainland Canico,—apparently Cancio, the Lucayan name of Florida. In the so-called Leonardo da Vinci’s Mappemonde, Florida appears as an island in a vast ocean that rolls on to Japan.[802]
