HOMANN HEIRS, "Plan de Corfu. Renvoy pour Les Nouvelles Fortifications Proieteés, et Executeés par S.E. Mr. Le Felt-Marechel C.te De Schulemburg / gravé par les Héritiers de Feu Monsieur le Docteur Hommann, Géographe", Nuremberg, 1735. Map dim. 77 x 74 cm. Faded printed inscription on lower right. An impressive, probably separately printed, plan of the defences of the city of Corfu and inner land, which defeated a Turkish siege in 1716 under the commander of Johann Mattias Von Schulenburg. Under the impressive title cartouche on the bottom-left, exists an extensive key in French pointing the important buildings, including batteries, gates, churches and religious centres such as the synagogue. On the right, a birds-eye view of the walls detailing the layers of bastions. The improved walls were planned and built by Johann Matthias von der Schulenburg (1661-1747), a German mercenary in the pay of the Venetians, as the Ottomans swept through the Morea in less than a hundred days in 1715. In July 1716 the Ottoman army of 33,000 landed on Corfu and laid siege to the city, but the walls, manned by only about 8,000 defenders, withstood several assaults before the Ottomans withdrew in August. Dedication to Alvise Pisani, the 114th Doge of Venice elected in 1735, the year of publication. Zacharakis 1664a. Very rare.
