This ancient stamp dates to the 22nd century BC, and is from the holy city of Nippur, located southeastern Iraq. Nippur was the religious centre of Mesopotamia for thousands of years, and was believed to have been where Enlil created mankind.
Translated, the inscription on the stamp reads: Narâm-Sîn built the house/temple of the god Enlil. As the British Museum state: “Such stamps were used to impress or mark the bricks of important religious and public buildings. They are therefore an important source for the identification of architecture and a valuable criterion for the date of a building.” The impression in front of the stamp is modern.
