Cuneiform tablet: quittance for a loan in silver. Culture: Old Assyrian Trading Colony. Dimensions: 4.6 x 4.7 x 1.5 cm (1 3/4 x 1 7/8 x 5/8 in.). Date: ca. 20th-19th century B.C..Kültepe, the ancient city of Kanesh, was part of the network of trading settlements established in central Anatolia by merchants from Ashur (in Assyria in northern Mesopotamia) in the early second millennium B.C. Travelling long distances, and often living separately from their families, these merchants traded vast quantities of goods, primarily tin and textiles, for Anatolian copper and other materials. Although the merchants adopted many aspects of local Anatolian life, they brought with them Mesopotamian tools used to record transactions: cuneiform writing, clay tablets and envelopes, and cylinder seals. Using a simplified version of the elaborate cuneiform writing system, merchants tracked loans as well as business deals and disputes, and sent letters to families and business partners back in Ashur.
