This is a 3D model of "The Sumerian King List" (Weld-Blundell-Prism) displayed at the Ashmoleon Museum in Oxford.
"The Sumerian King List" is a prism made of baked clay, showing cuneiform inscriptions.
These inscriptions are listing the former Sumerian rulers in the region of todays southern Iraq.
They start in a mythical past (antediluvian or pre-flood times) and end in the time it was written (Sin-magir of the Isin dynasty).
Dating: Mesopotamian Middle Bronze Age, c. 1827-1817 BC
