The king of Kish even sometimes enforced order inSumer. For example, Enannatum’s son, Enmetena, wrote that theborder between Lagash and Umma had been determined by thegreat god Enlil himself and had been confirmed by the king of Kish:“Mesalim, king of Kish, at the command of (the god) Ishtaran,measured the field and set up a (boundary-) stone there.” Theauthority of the king of Kish was therefore acknowledged, at leasttemporarily, by both the king of Umma and the king of Lagash.
There is an interesting example of the mnemonic use of stone here in ancient Sumer. It serves as a boundary/border marker by its physical presence, but apart from any (other local) mnemonic uses, it also carries an inscription as a secondary form of long term written memory.
