Paytier-Pellet (Depot), "Carte de la Moree redigee et grave au Depot General de la Guerre d apres la triangulation et les leves executes en 1829, 1830, 1831 par les officiers de l Etat Major...", Paris, 1832. THE FAMOUS FRENCH EXPEDITION MAP. Impressive lithographed military topographic map of Peloponnesus (120x120 cm), originally printed in 6 sheets of 60x40cm each, all sheets segmented, folded and in an elegant contemporary sleeve 21x17cm rubbed. In 1:200.000 climax, the first scientific map of any Greek area. With the seventh sheet, 60x40cm, with maps of Navarino, Mantinia and Messini in more detailed scales. Complete, all Peloponnesus sheets ever printed. Few contemporary marginal manuscript inscriptions, overall in very good condition. According Ploutoglou, Pazarli and Livieratos ("Two emblematic French maps of Peloponnesse", Thessaloniki University 2013), with the arrival of French troops in Morea under Maison in 1828, the French General Staff ordered the preparation of a detailed map using systematic geodetic and topographical measurements in the largest until then scale. The geodetic work started in 1829 and completed in 1831. The detailed initial work was very rigorous, including height measurements, but the delay made the French to decide a simplification of the procedures on the field. Peytier (1793-1864) a specialist engineer-geodetic was the chief of the French team. Although the result was not perfect, this map was by far, the best ever produced for any part of Greece and the first scientific map of Greece, using triangulation methods, ever published. A LANDMARK IN GREEK CARTOGRAPHY. EXTREMELY RARE.
