In Sumerian and Akkadian mythology Asaruludu is one of the Anunnaki. His name is also spelled Namshub, Asarludu, and Asarluhi (𒀭𒍂𒇽𒄭). The etymology and meaning of his name are unclear. Asaruludu served as an exorcist in Sumerian religious rituals. As Namshub (shining), he is considered a protective deity, "the shining god that illuminates our path". The Enuma Elish describes Asaruludu as "the light of the gods". Another version states he is "the wielder of the flaming sword" and "ensures the most perfect safety".
