A large-scale sea chart of the southern portion of South America below 15 degrees south latitude. This records San Salvador on the Brazilian coast and Lima on the west coast. It extends southwards to record Tierra del Fuego. The only internal detail delineated is the region from Lake Titicaca to the silver mountain of Potosi. Richard Mount (1654-1722) was apprenticed to William Fisher and married his daughter Sarah in 1682. Two years later Fisher and Mount formed a partnership. Their early sea atlas publications like their competitors were similarly entitled and included the ‘Atlas Maritimus’. Mount’s own apprentice Thomas Page (fl.1700-d.1733) joined him in 1698. One of their earliest publications is the ‘Atlas Maritimus Novus’ in 1702 published in a further edition in 1708. Only two examples of the first edition can be traced: the Library of Congress and the National Maritime Museum, Greenwich. That first edition contained this new chart. It has not been identified in any edition of the Fourth Part of the English Pilot which was devoted to America making this an extremely rare chart.

Richard Mount was born in 1654 and died 29 June 1722 after being kicked in the leg by a cart horse on London Bridge. The firm of Mount and Page continued for over a century publishing sea charts. The British Prime Minister David Cameron is a direct descendant of the Mount family. Provenance: Jonathan Potter 2000; Juan and Peggy Rada Collection.
