Weld-Blundell Prism

The list begins with the antediluvian rulers and ends with Sin-magir of the Isin dynasty (r. 1827–1817). 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 (counted in sars and nerah), as a result of which many scholars consider this work to be more artistic than historical.

Various theories are being 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 (3600 years) and ner (600 years), the units of time measurement in the Sumerian number system, should be taken as years and months, respectively.

This text of the Old Babylonian period (Isin dynasty, c. 1827 – c. 1817 BCE) is inscribed in traditional Sumerian cuneiform.
