Fine chart of Bombay (Mumbai), by one of France's leading chart makers of the late 18th Century.
The chart provides a very detailed view of the harbor complete with soundings, navigational hazards, and anchorages. The most attractive feature of the chart is the beautifully engraved prominent landmarks shown as they would be seen from aboard ship, including mountains, forts, houses, and churches.
One of the earliest obtainable large format maps of Mumbai.
Jean-Baptiste Nicolas Denis d’Après de Mannevillette (1707-1780) was a French sailor and hydrographer celebrated for his excellently-rendered charts. Mannevillette was born into a maritime family and he joined his father on a French East India Company voyage to India aged only twelve. A clever boy, he returned to France to study navigation, chartmaking, and mathematics with Joseph-Nicolas De L’Isle. At nineteen, he was back at sea, working his way up the ranks of the French East India Company’s merchant fleet.
In his work with the company—he was eventually promoted captain—Mannevillette sailed to the Indian Ocean many times. En route, he was constantly gathering and correcting hydrographic knowledge. He was also skilled at using the latest navigational instruments, like the octant and later the sextant, which allowed him to make his charts especially accurate for their time. He compiled his work into his most significant publication, Le Neptune Oriental, which was commissioned by the French East India Company and first published in 1745. It was released in an expanded second edition in 1775, with posthumous expansions in 1781 and 1797.
The Neptune earned Mannevillette many accolades. The company made him Director of Charts at Lorient in 1762. In 1767, King Louis XV gave him the Order of St. Michael and named him an associate of the Royal Marine Academy.
