In Hittite mythology, Illuyanka was a serpentine dragon slain by Tarhunt, the Hittite incarnation of the Hurrian god of sky and storm. It is known from Hittite cuneiform tablets found at Çorum-Boğazköy, the former Hittite capital Hattusa. The contest is a ritual of the Hattian spring festival of Puruli. The dragon was the symbol of the goddess and she was destroyed.
In one version, the two gods fight and Illuyanka wins. Teshub then goes to the Hattian goddess Inaras for advice. Having promised her love to a mortal named Hupasiyas in return for his help, she devises a trap for the dragon. She goes to him with large quantities of food and drink, and entices him to drink his fill. Once drunk, the dragon is bound by Hupasiyas with a rope. Then the Sky God Teshub appears with the other gods and kills the dragon.
