Grouped under commercial weights, coin weights, weights made of coins, disc-shaped weights, vessel-shaped weights, and glass weights, these artifacts offer new information for researchers about the Byzantine economic system from the 3rd century to the 13th. Continuing the series, a new volume covering approximately 5000 weights from ancient Mesopotamia, Seljuk, and Ottoman periods, all registered with the collection, is forthcoming.
