Pieter Goos (1616–1675). Accurate nautical chart of the Celtic Sea oriented north to the left. The title cartouche depicts Nereus and his children, the Nereids, with cross staffs and an astrolabe, all important instruments of navigation. Marking the southern coasts of Ireland and Wales, Cornwall, Brittany and the northern coast of Spain to Cape Finisterre, its purpose is to show the approaches to the English Channel, an important waterway for the Dutch East India Company. The route was infamous because determining latitude at sea was difficult: indeed, it was when the British fleet ran aground on the Isles of Scilly in 1707 that the famous Longitude Award was initiated. Amsterdam, circa 1666. Size: 18” x 23” inches / 46 cm x 58 cm
