Philoctetes

Philoctetes was the son of King Poeas of Meliboea, and gained early fame as an archer. He (or, in other versions, his father Poeas) was the only one willing to light Heracles' funeral pyre (to end the agony caused by the poisoned shirt his wife had unwittingly given him), for which favour Heracles granted him his bow and poisoned arrows. As one of the many eligible Greeks who competed for the hand of Helen of Sparta, he was required to participate in the Trojan War conflict to reclaim her. However, on the way to Troy, he was stranded on the island of Lemnos (or Chryse), where he received a snake wound on his foot that festered and gave off a terrible smell, so much so that Odysseus persuaded his men to continue on to Troy without him. The captured Trojan seer Helenus later revealed under torture that the Greeks needed Philoctetes and Heracles' bow and arrows in order to win the war, and Odysseus and Diomedes returned to Lemnos to fetch him. He was among those chosen to hide inside the Trojan Horse and, during the sack of the city, killed many famed Trojans. After the war, he returned home to Meliboea, where he encountered a revolt, and from there he went on to Italy.
