Oenone, in Greek mythology, a fountain nymph of Mount Ida, the daughter of the River Cebren, and the beloved of Paris, a son of King Priam of Troy. Oenone and Paris had a son, Corythus, but Paris deserted her for Helen. Bitterly jealous, Oenone refused to aid the wounded Paris during the Trojan War, even though she was the only one who could cure him. She at last relented but arrived at Troy too late to save him. Overcome with grief, she committed suicide. The 19th-century English poet Alfred, Lord Tennyson, wrote a poem about her, “The Death of Oenone.”
