Iluwer (ʾlwr, 'the god Wer') is known from the Aramaic stele of Zakkur, king of Hamath and Luash (KAI 202), discovered in 1903 at Tell Afis southeast of Aleppo and dated to about 800 BCE. The stele opens as 'the stele which Zakkur set up for Iluwer', making him the deity of the sanctuary at Apish and the personal or dynastic god of the king, while Baalshamayin, the lord of the heavens, is the god who answered Zakkur through seers during the siege of Hazrach. Scholars identify Iluwer as an Aramaean continuation of Wer (Mer, Itur-Mer), a storm god venerated on the middle Euphrates since the third millennium BCE, whose cult travelled westward with populations settling in the kingdom of Hamath. He appears nowhere else by this name in Aramaic epigraphy, which makes the Zakkur stele the essential witness to his cult.
