Mesopotamian duck weights
Mesopotamia, about 2000-500 B.C.
Official weights in the shape of a sleeping duck were common in Mesopotamia from about 4000 years ago. On some an inscription gives the king's name and the weight, for example: 'half standard mina belonging to Ahhiya, son of Mudammiq-Adad, the diviner'.
Two stone duck-shaped weights, about 1000-500 BC, excavated by Hormuzd Rassam at Sippar, Southern Iraq, and about 2000-1000 B.C.
