Uà ¡umgallu or Ushumgallu (Sumerian: uà ¡um.gal, "Great Dragon") was one of the three horned snakes in Akkadian mythology, along with the Baà ¡mu and Muà ¡maá¸«á¸«à «. Usually described as a lion-dragon demon, it has been somewhat speculatively identified with the four-legged, winged dragon of the late 3rd millennium BCE.
Tiamat is said to have "clothed the raging lion-dragon with fearsomeness" in the Epic of Creation, Enuma Elish. The god Nabû was described as "he who tramples the lion-dragon" in the hymn to Nabû. The late neo-Assyrian text "Myth of the Seven Sages" recalls: "The fourth (of the seven apkallu's, "sages", is) Lu-Nanna, (only) two-thirds Apkallu, who drove the uà ¡umgallu-dragon from ÃÂ-ninkarnunna, the temple of Ià ¡tar of à  ulgi."
Aà ¡à ¡ur-nÃÂá¹£ir-apli II placed golden icons of uà ¡umgallu at the pedestal of Ninurta. Its name became a royal and divine epithet, for example: uà ¡umgal kalià ¡ parakkë, "unrivaled ruler of all the sanctuaries". Marduk is called "the uà ¡umgallu-dragon of the great heavens".
In the god list An = Anum Uà ¡umgal is listed as the sukkal (vizier) of Ninkilim.
