Jacques-Raymond Grenier (1736-1803) was a French hydrographer known primarily for his charts of the Indian Ocean. Grenier spent the years of 1768 and 1769 exploring and charting the various islands in the Indian Ocean, particularly where the French had colonial possessions and interests. He wrote of his discoveries in his "Mémoires de la campagne de découvertes dans les mers des Indes" published in 1772. On the basis of Greniers discoveries of the currents and winds prevailing during the southwest and northeast monsoons in the Indian Ocean he discovered more direct and hence faster routes to and from French colonial possessions in India, including the Coromandel Coast of India and to the straits of Malacca, decreasing the length of such voyages by over 3,000 kilometers. This map depicts those currents and winds and shows the new shorter courses discovered by Grenier. This chart was published for the English market by Robert Sayer and Jonathan Bennett in 1778., by msr. le vicomte Grenier 1776., Map showing the currents in the Indian Ocean during the NE monsoon., Prime meridian: London., Includes the ancient course of the route to India., Plate 6 from: The Oriental pilot, or, A select collection of charts and plans ... for the navigation of the country trade in the seas beyond the Cape of Good Hope.
