This map of the Atlantic Ocean depicts the areas explored by Anthony Knivets, an English sailor who traveled with Thomas Cavendish in 1591 on a voyage to Brazil. After developing frostbite in the Strait of Magellan, Knivets was abandoned on a remote island, where he was captured by the Portuguese. Knivets was forced to work as a slave for many years in South America, but escaped and fled to Angola and eventually made his was back to England. Knivets' memoir of his travels was published by Samuel Purchas in his Purchas his Pilgrimage in 1613. This map was published in van der Aa's compilation of early voyages of exploration.
A dark impression with moderate toning that affects the left 2/3 of the map and scattered foxing confined to the blank margins. The bottom left corner of the sheet has been trimmed, well away from the image.
