As excerpted from Historia general de los hechos de los Castillanos en las islas i tierra firme del Mar Oceano (General History of the Deeds of the Castilians in the Islands and Mainland of the Ocean Sea), first published 1601-1615 by Antonio de Herrera y Tordesillas narrating Ponce de Leon’s 1513 voyage to the New World.
