Kudurru

Kudurru was a type of stone document used as boundary stones and as records of land grants to vassals by the Kassites in ancient Mesopotamia between the 16th and 12th centuries BCE. The word is Akkadian for "frontier" or "boundary." The kudurrus are the only surviving artworks for the period of Kassite rule in Babylonia with examples kept in the Louvre and the National Museum of Iraq.
