Uridimmu
Urdimmu, “Mad/raging Lion,” Sumerian UR.IDIM and giš.pirig.gal = ur-gu-lu-ú = ur-idim-[mu] in the lexical series ḪAR.gud = imrû = ballu, was an ancient Mesopotamian mythical creature in the form of a human headed lion-man who first appears during the Kassite period. He is pictured standing upright, wearing a horned tiara and holding a staff with an uskaru, or lunar crescent, at the tip. The lexical series ḪAR-ra=ḫubullu describes him as a kalbu šegû, “rabid dog,” but due to the propensity for Sumerian culture to group canines and felines together (ur.maḫ, big dog = lion) and Akkadian to separate them (nēšu, labbu = lion), the issue remains unresolved.
