In 1570, mapmaker Abraham Ortelius plotted the Galapagos Islands, calling them the Isolas de Galapagos, or "Islands of the Tortoises," based on sailors' descriptions of the many tortoises inhabiting the islands. By the 17th century, the Galapagos Islands became a popular hideout for British buccaneers who pirated Spanish ships and looted Spanish settlements in Central and South America. These buccaneers and British whalers used the islands as a source of food on long journeys.
