inscription mentioning the place and dated to the first year of Enshakushanna, who almost certainly preceded him. The Weidner Chronicle (ABC 19:51) states that it was Sargon who "built Babylon in front of Akkad." The Chronicle of Early Kings (ABC 20:18–19) likewise states that late in his reign, Sargon "dug up the soil of the pit of Babylon, and made a counterpart of Babylon next to Agade." Van de Mieroop suggested that those two chronicles may refer to the much later Assyrian king, Sargon II of the Neo-Assyrian Empire, rather than to Sargon of Akkad. Some of the regnal year names of Sargon are preserved, and throw some light in the events of his reign, particularly the conquest of the surrounding territories of Simurrum, Elam and Mari, and Uru'a, thought to be a city in Elam: Historiography Language and script used in records Sargon appears to have promoted the use of Semitic (Akkadian) in inscriptions. He frequently calls himself "king of Akkad" first, after he apparently founded the city of Akkad. He appears to have taken over the rule of Kish at some point, and later also much of Mesopotamia, referring to himself as "Sargon, king of Akkad, overseer of Inanna, king of Kish, anointed of Anu, king of the land [Mesopotamia], governor (ensi) of Enlil". During Sargon's reign, East Semitic was standardized and adapted for use with the cuneiform script previously used in the Sumerian language into what is now known as the "Akkadian language". A style of calligraphy developed in which text on clay tablets and cylinder seals was arranged amidst scenes of mythology and ritual. Year names While various copies of the Sumerian king list and later Babylonian chronicles credit Sargon with a reign length ranging from 34 to 56 years, dated documents have been found for only four different year-names of his actual reign. The names of these four years describe his campaigns against Elam, Mari, Simurrum (a Hurrian region), and Uru'a (an Elamite city-state). Nippur inscription Among the most important sources for Sargon's reign is a tablet of the Old Babylonian period recovered at Nippur in the University of Pennsylvania expedition in the 1890s. The tablet is a copy of the inscriptions on the pedestal of a statue erected by Sargon in the temple of Enlil. Its text was edited by Arno Poebel (1909) and Leon Legrain (1926).
