Ex Libris Edward Theodore Newell. The only edition of a comprehensive and profound treatise on the coins of the kingdom of Osroen (Upper Mesopotamia) and its capital Edessa, composed by the multifaceted German professor of Greek and Roman Antiquities at the St. Petersburg Academy of Sciences (1726-1737). This text was the first numismatic work printed in Russia. The volume provides the complete history up to 1400 of the city of Edessa, now called Urfa, in the southeast of Turkey. Under the Roman Empire it became a province and at the fall of the Empire, the city was claimed by both the Persians and the Byzantines, and then conquered by the Arabs. It was later ruled by the Franks and later became part of the Ottoman Empire. The coins depicted in the text date from the period of the independent kingdom.gr. 1016
