Don Juan de la Cruz Cano y Olmedilla and others. “A Chart of the Straits of Magellan.” London: R. Sayer & J. Bennett, 1775. 20 1/4 x 27 1/8 (neat lines). Engraving. Original outline color. One old repaired tear. Some chipping at edges. Overall, good condition.
A wonderfully detailed chart of the Straits of Magellan. Issued by the leading British map publisher of the late eighteenth century, this map is primarily based on a chart issued in Madrid in 1769, though “Improved from the Observations and Surveys of Captns. Byron, Wallis and Carteret compared with those of Monsr. De Bougainville.” The map shows excellent detail of the strait, with soundings, currents, and much topographical information along the two banks to help a navigator mark his position. A larger scale map is included in an inset at the top to show the strait in context of the entire tip of the continent. An excellent eighteenth century map.
