Idlurugu (Sumerian: i7-lú-ru-gú, also read Ilurugu) or Id (dÍD) was a Mesopotamian god regarded as both a river deity and a divine judge. He was the personification of a type of trial by ordeal, which shared its name with him. Idlurugu was chiefly worshiped in Id (modern Hit). However, he was not strongly associated with any location, but rather with trial of water alone, and as such appears in sources from many parts of the Ancient Near East.
