Iraq: Ishchali(?); Early second millennium B.C. Hematite. Oriental Museum. Purchased in Baghdad, 1930. "The Mesopotamians used sets of standard weights in conducting business and set stiff penalities for those who used false weights. The weights themselves were usually made of a very hard stone like hematite. A simple barrel shape was the most common form, but weights such as these in the form of a duck, with its neck and head resting along its back, were also prevalent."
