Eleutherios or Lefteris (Greek: Ελευθέριος, "the liberator") is an epithet and formal attribution in the Greek pantheon, including:
From Eleuther, son of Apollo and Aethusa.
- He is renowned for having an excellent singing voice, which earned him a victory at the Pythian games,
- and for having been the first to erect a statue of Dionysus.
- as well as for having given his name to Eleutherae.
- His sons were Iasius.
- and Pierus.[citation needed] He also had several daughters, who spoke impiously of the image of Dionysus wearing a black aegis, and were driven mad by the god; as a remedy, Eleuther, in accordance with an oracle, established a cult of "Dionysus of the Black Aegis".
- Eleuther, a variant of the name Eleutherios, early Greek god who was the son of Zeus and probably an alternate name of Dionysus.
- Eleuther, one of the twenty sons of Lycaon. He and his brother Lebadus were the only not guilty of the abomination prepared for Zeus, and fled to Boeotia.
- Eleuther, one of the Curetes, was said to have been the eponym of the towns Eleutherae and Eleuthernae in Crete.
