R.W. Seale sculp. [London: for the author by John and Paul Knapton, 1748.] Engraved map. 530 x 500mm (20¾ x 19¾"). Folded as issued, splits in folds, paper toned. A map of South America below Rio Grande in Brazil and Juan Fernandez Island in the Pacific (where Alexander Selkirk was marooned), marking the route taken by George Anson when rounding Cape Horn on his circumnavigation, 1740-44. The rough seas and gales meant that 'dead reckoning' was ineffective, so two estimated routes are shown south and west of the cape. On the map the Falklands have only a partial outline and, further north, the mythical 'Pepys Island', likely to be a mis-mapped Falkands, is marked. Anson's voyage was one of the last great buccaneering voyages, an official expedition to the South Seas to harass the Spanish bases but, more importantly, plunder their shipping. A main target was one of the richly-laden Manila galleons that crossed between Acapulco in Mexico and Manilla the Philippines. A stroke of luck presented them with one laden with 1.3 million silver pieces of eight; on their return to London, thirty-two wagons were needed to transfer them to the Tower of London. Published in Anson's own account, ''A Voyage Round the World, in the years MDCCXL, I, II, III, IV''.
