Described in inscriptions as a supreme master, his name in Greek is Zeus Hypsistos. Master of the world and "master of the heavens", he governs the Sun (Malakbel) and the Moon (Aglibol). The iconography reveals that they are closely linked to his person. As master of the heavens, he is symbolised by an eagle with outstretched wings reigning over the stars. He is the leader of a divine triad different from that of Bel.

He is, moreover, the god who brings the rain and therefore water for crops. In a region like Palmyra where caravans were the main source of wealth, he protects his followers - essentially livestock breeders and farmers - from drought. He was also worshipped by an agrarian cult, and frequently depicted holding a bouquet of corn and fruit or a grape vine.
