Uridimmu

Ur(i)dimmu, meaning "Mad/howling Dog" or Langdon's "Gruesome Hound",[1] (Sumerian: 𒌨𒅂UR.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 dog-man whose first appearance might be during the Kassite period, if the Agum-Kakrime Inscription proves to be a copy of a genuine period piece.

He is pictured standing upright, wearing a horned tiara and holding a staff with an uskaru, or lunar crescent, at the tip.

He appears in later iconography paired with Kusarikku, "Bull-Man", a similar anthropomorphic character, as attendants to the god Šamaš.

He was especially revered in the Eanna in Uruk during the neo-Babylonian period where he seems to have taken on a cultic role, where the latest attestation was in the 29th year of Darius I.

[4] As one of the eleven spawn of Tiamat in the Enûma Eliš vanquished by Marduk, he was displayed as a trophy on doorways to ward off evil and later became an apotropaic figurine buried in buildings for a similar purpose.
