Tarḫunna

Tarḫunna is the Hittite god of weather, storms, and the sky, whose name derives from the Hittite or Luwian verb tarḫ meaning "to overcome, to conquer" or "to defeat." This etymology is reflected in his epithets such as "the Weather god of Heaven" and "the Lord of the Land of Hatti." The name is a cognate of the Hittite verb tarḫu-zi and traces back to the Proto-Anatolian weather god *Tṛḫu-ent- ("conquering"), ultimately from the Proto-Indo-European root *terh₂- meaning "to cross over, pass through, overcome." Similar forms appear in other Anatolian languages, such as Luwian Tarḫunz, and in Carian, Milyan, and Lycian.

Mythology and Role

As the primary storm god of the Hittite pantheon, Tarḫunna was a powerful deity responsible for natural phenomena such as thunder, rain, and storms — forces essential for agriculture and survival. He was closely identified with the Hurrian god Tešub, with whom he shared the role of storm god, and sometimes with the Northwest Semitic god Hadad. Notably, Tarḫunna was the slayer of the dragon Illuyanka, a mythological dragon that appears in Hittite creation myths such as the Illuyanka myth, which recounts the struggle between the storm god and the serpentine chaos monster.

The god's functions are believed to have originated from the Proto-Indo-European deity Perkwunos, but the Hittites and related Anatolian peoples replaced the old name with the new epithet *Tṛḫu-ent- ("conquering"). This epithet was chosen in part because it sounded similar to the name of the Hattian storm god Taru, facilitating integration into local traditions. Tarḫunna was widely worshipped across Anatolia, appearing in numerous inscriptions and monumental art, often depicted holding a lightning bolt or a mace.

Related Names and Cult

The Luwian form, Tarḫunz, is a close cognate, while Carian Trquδ- and Lycian Trqqas bear the same root. The name and cult of Tarḫunna influenced later Anatolian and Near Eastern religious syncretism, especially during the period when the Hittite Empire exported its culture and language into peripheral regions through trade and warfare. Temples and open-air sanctuaries at sites such as Hattusa (the Hittite capital) and Yazılıkaya feature reliefs and inscriptions honoring Tarḫunna, underscoring his central role in the state religion.
