How did Anatolia's dependence on rain shape the importance of the Hittite weather god?

In the context of Anatolian religion, the Hittite weather god—known as Tarhun (or Tarhund) in Hittite and Luwian—attained supreme status primarily because the region was heavily dependent on rain for its agricultural fertility.1

As the provider of life-sustaining rain, the weather god was elevated to the position of chief deity within the official pantheon under the title "weather god of Hatti". This role extended beyond agriculture; he was viewed as the embodiment of the state in action, a figure who bestowed kingship, secured victory in war, and represented the nation in diplomatic dealings with foreign powers.12

The importance of this dependence is reflected in the Hittite theological view, which recognized various manifestations of the deity—such as the weather god of the rain, clouds, and lightning—as essential aspects of the divine. His significance was further cemented by his association with the sacred bull, a symbol of power and fertility, often depicted in art carrying a three-pronged thunderbolt to signify his control over the elements.321
