Le Rouge, "La Moree dapres Coronelli", Paris, Chez Le Rouge, Rue des Augustins, 1770. Separately printed, copper engraved map (50 x 34cm) of Peloponnesus and surrounding areas. Le Rouge (1712-1790) was an important military engineer and cartographer of the middle 18th century. With the start of the Russian-Turkish war of 1769-1774 he published two separately printed general maps of southern Russia (1769) and as the war continued, he issued (March 1770) a military Atlas with 10 maps covering in details and in separate maps the fronts in the northern Black Sea. But nobody could predict that the Russians planned to send a fleet in Greece to attack the Ottoman fleet. At the time the Russians were landing Koroni in April 1770, the atlas was already out-of-date. Le Rouge tried to complete the map, but the Greek lands were poorly covered geographically. It is very interesting that he preferred an early 18th century Venetian map as a base-map, most probably because the Venetians were the only ones that made cartographic measurements during their rule in Morea. In the same time the Russian fleet operated in the Aegean and Russian army invaded Moldavia. In total 4 more maps were issued separately, in very small print run, during late 1770/1771 and for this reason are extremely rare today. Not in Zacharakis, Not in BNF. Two copies only identified in Public institutions worldwide. Extremely Rare.
