Weld-Blundell Prism

The Weld-Blundell Prism is a clay, cuneiform-inscribed vertical prism housed in the Ashmolean Museum in Oxford. The prism was found in a 1922 expedition in Larsa in modern-day Iraq by British archaeologist Herbert Weld Blundell. The prism's four sides, about, are inscribed in the Sumerian language with lists of the kings of Sumer; each side contains the text in two columns: this is the famous Sumerian King List. It is considered the most complete of the Sumerian King Lists which have been found, of which there are approximately 25 more or less complete fragments as of 2016.
The list begins with the antediluvian rulers and ends with Sin-magir of the Isin dynasty. The list was most likely written in Sin-magir's final year, or soon after. Many, especially antediluvian, kings are credited with incredibly long reigns, as a result of which many scholars consider this work to be more artistic than historical.
Various theories have been constructed in an attempt to explain such large numbers. They are supposed to express the great importance of rulers who were considered demigods. According to another version, sar and ner, units of time measurement in the Sumerian number system, should be taken as years and months, respectively.
This text of the Old Babylonian period is inscribed in traditional Sumerian cuneiform.
