John Drake (c1562-?) was cousin to the renowned English navigator Francis Drake, serving as his personal servant during the second voyage of world circumnavigation (1577-1580). On a subsequent expedition, in 1584, John Drake was captured by native Americans in the River Plate estuary, later being taken prisoner by the Spanish at Buenos Aires, and questioned at Santa Fe. Three years later (1587) he was examined by the Inquisition in Lima: this section of his evidence describes that earlier visit to Patagonia and the crossing of the Magellan Strait.
