The cult of the Heliopolitan Triad was Canaanite in essence but the Romans adopted it when they conquered the city of Heliopolis (modern Baalbeck) in the Beqaa Valley of Lebanon. The Canaanite god BaĘżal (Hadad) was equated with Jupiter Heliopolitanus, Astarte or Atargatis with Venus Heliopolitana and Adon, the god of spring, with Mercury. The Romans built magnificent temples for the Heliopolitan Triad in Heliopolis. Votives dedicated to the cult were also found in the village of Bechouat in Lebanon.
