When Heracles was near his death, he wished to be burned on a funeral pyre while still alive. In the play Philoctetes, Sophocles references the myth in which no one but Philoctetes would light Heracles' funeral pyre, and in return for this favor Heracles gave Philoctetes his bow (seen in later texts, such as Ovid's Metamorphoses). Philoctetes left with the Greeks to participate in the Trojan War, but was bitten on the foot by a snake while walking on Chryse, a sacred ground. The bite caused him constant agony, and emitted a horrible smell. For this reason he was left by Odysseus and the Atreidai (sons of Atreus) on the desert island Lemnos.
Ten years pass, and the Greeks capture the Trojan seer Helenus, son of Priam. He foretells that they will need the master archer Philoctetes and the bow of Heracles to win the war. Odysseus sails back to Lemnos with Neoptolemus (son of Achilles) to get Philoctetes. The task is not easy, as Philoctetes bitterly hates Odysseus and the Greeks for leaving him there.
