As a result of Gomes' expedition, cartographer Diogo Ribeiro was the first to accurately portray North America with a continuous coastline stretching from Florida to Nova Scotia.
[3] In 1523 Gomes received authorization from the Spanish Crown to search along the North American coast for an alternate passage to Asia that would be quicker and easier than the Strait of Magellan.
Knowledge of the voyage comes from brief second-hand summaries by contemporary historians Oviedo, Peter Martyr, and Alonzo de Santa Cruz, as well as cartographic information captured by Diogo Ribeiro.
Gomes sailed up the Penobscot River to the future site of Bangor, Maine, naming the waterway "El Rio de Las Gamas".
[2][6] While exploring the area of Penobscot, Gomes abducted at least 58 natives and took them back to Spain as evidence of a potentially lucrative slave trade.
Peter Martyr claimed that when the message reached court, the word for slaves (esclavos) had been misunderstood to mean cloves (clavos), creating for a moment the false impression that Gomes had found a route to the Orient.
[7][8] As a result of Gomes' expedition, cartographer Diogo Ribeiro's 1525 Castiglione map was the first to accurately portray North America with a continuous coastline stretching from Florida to Nova Scotia.
