What is "teshub"

Teshub (also written Teshup or Tešup; cuneiform ; hieroglyphic Luwian , read as Tarhunzas) was the Hurrian god of sky and storm. Taru ( Luwian Tarhun / Tarhunt- / Tarhuwant- / Tarhunta) -- a word derived from the Hattic root *tarh "to defeat, conquer") -- was the name of a similar ( Indo-European, pre- Hittite) Hattic Storm God, whose mythology and worship as a primary deity continued and evolved through descendant Luwian and Hittite cultures. Taru was ultimately assimilated into and identified with the (non- Indo-European) Hurrian Teshub around the time of the religious reforms of Muwatalli II, ruler of the Hittite New Kingdom in the early 13th century BCE. These reforms can generally be categorized as an official incorporation of Hurrian deities into the Hittite pantheon, with a smaller number of important Hurrian gods (like Teshub) being explicitly identified with preexisting major Hittite deities (like Taru). Teshub reappears in the post-Hurrian cultural successor kingdom of Urartu as Tesheba, one of their chief gods; in Urartian art he is depicted standing on a bull.
