Although Amar-Suen succeeded his father Shulgi (2094-2047) and ruled as the third king of Ur III dynasty for a period of nine-years (2046-2038), little is known about him. He is not mentioned in economic texts that date to his father’s reign, and the only documents that specifically mention Amar-Suen by name and that date to his reign are building inscriptions (Michalowski 1977:155).
This brick inscription (ca. 1998-1989 BC) follows the standard literary formula for building inscriptions that consists of several lines of epithets and a description of a building or monument that the king commissioned in honor of the god(s). In this text the god Enlil sanctions Amar-Suen’s rule, and he is credited with building a basin for the god Enki at Nippur. Matouš suggests that this basin (referred to as an abzu/zu-ab in the text) was a temple basin that was filled with water and was a symbol of the junction of the physical world and the deep waters of the underworld (Matouš,1962, 3)
