As part of the proceeds of the fifth postwar season at Nippur (1955-56), sponsored jointly by the Oriental Institute of the University of Chicago and the American Schools of Oriental Research, the Yale Babylonian Collection received two clay fragments,' not necessarily from the same jar sealing. They preserved scattered sections of the impression of a cylinder seal dated to the reign of Amar-Sin, third ruler of the Third Dynasty of Ur, about 2040 B.C. according to the middle chronology. The fragments were unfortunately so poorly preserved that the seal impression on them could not be adequately restored. Fortunately, the epigraphist of the expedition, Professor Albrecht Goetze of Yale University, had careful notes on the results and in addition indicated that adequate photographs were available at the Oriental Institute, University of Chicago.
