Gomez commenced his exploration on the coast of South Carolina, and proceeding thence northwardly, reached the Rio de la buelta, where, as that name denotes, he commenced his return, on the island of Cape Breton. He carefully observed the rivers, capes and bays, which occur within those limits, entering the Chesapeake, Delaware, Hudson and Penobscot, to which he gave appropriate names, derived from the church calendar, or from some characteristic of the locality. He was for a while encouraged to believe, in consequence of the great flood of water which he found issuing from the Penobscot, or Rio de Gamos, (Stag river), that he had there fallen upon the desired strait. Though unsuccessful in the object of his search, he nevertheless accomplished an important service for geographical science, in determining that no such passage existed within the region he had sailed. Taking in a cargo of Indians from the islands of the great bay, he continued his course to the south, and running along the coast of Florida, returned to Spain by way of Cuba. [Footnote: Peter Martyr, Dec. VI. c. 10. Herrera, III, VIII. S. Cespedes, Yslario General, in Ms. Cespedes was cosmographer major of the Indies in Seville and wrote many geographical works early in the seventeenth century. His Yslario General, embracing a history of the islands of the world, exists in the Biblioteca Nacional in Madrid.]
The authenticity of this voyage is established by Oviedo and Peter Martyr both of whom were eyewitnesses of the Indians which Gomez brought home and exhibited at Toledo. Both of these writers have given short accounts of the voyage, which, as it was not successful in the purpose for which it was undertaken and promised no returns of gold, excited no public attention. The results were, however, interesting to the hydrographers of Spain, who soon prepared charts of the coast, according to his exploration, among which that made by Diego Ribero, associate of Gomez at the junta of Badajos, and royal cosmographer, will demand especial attention.
The voyage of Gomez and what he had accomplished became immediately known to the world at large by printed publications. He arrived home on his return in November 1525; and three months afterwards Oviedo published his first work, addressed to the emperor, in which he makes the following brief mention of the expedition.
