Dorn, “Die Meerenge der Dardanellen welche den Archipelagum mit der Schwarzen meer rereinigt”, Leipzig, 1771. Splendid view of the Dardanelles, the sea of Marmara and Constantinople from the very rare book on the contemporary war: “Geschichte des Kriegs Russland, Polen und der Othomanische Pforte”. The original 18th century views of the area and Constantinople are few, as almost all editors followed earlier depictions. Very rare.
