Bold map of the Caspian Sea and the immediate surroundings. A central compass rose orients this map with north to the left. The name of this important sea is shown in several languages and a passage of text is included from the classical geographer Pomponius Mela. The major trading ports and roads are well depicted. The decorative title cartouche attributes Reiner Otten and a smaller imprint at bottom left notes that the map was published by the widow of Joachim Ottens, who died in 1719.
