in fabulous history, a celebrated foot-slayer, son of Priam and Hecuba. He was greatly respected by all the Trojans. When Delphous was given in marriage to Helen in preference to himself, he resolved to leave his country, and retired to Mount Ida, where Ulysses took him prisoner by the advice of Calchas. As he was well acquainted with futurity, the Greeks made use of prayers, threats, and promises, to induce him to reveal the secrets of the Trojans; and either the fear of death, or gratification of resentment, seduced him to disclose to the enemies of his country, that Troy could not be taken whilst it was in possession of the palladium, nor before Polydectes came from his retreat at Leuynos and affilited to support the siege. After the ruin of his country, he fell to the share of Pyrrhus the son of Achilles, and saved his life by warning him to avoid a dangerous tempest, which in reality proved fatal to all those who set sail. This endeared him to Pyrrhus; and he received from his hand Andromache the widow of his brother Hector, by whom he had a son called Cephrinus. This marriage, according to some, was consummated after the death of Pyrrhus, who lived with Andromache as with a wife. Helenus was the only one of Priam's sons who survived the ruin of his country. After the death of Pyrrhus he reigned over part of Epirus, which he called Chaonia in memory of his brother Chaon, whom he had inadvertently killed. Helenus received Aeneas as he voyaged towards Italy, and foretold him some of the calamities which attended his fleet. The manner in which he received the gift of prophecy is doubtful.
