In the later form of the story Philoctetes was the friend and armour-bearer of Heracles, who presented him with his bow and poisoned arrows as a reward for kindling the fire on Mt Oeta, on which the hero immolated himself.
According to other accounts, having been made prisoner by a stratagem of Odysseus, he declared that Philoctetes must be fetched from Lemnos before Troy could be taken; or he surrendered to Diomedes and Odysseus in the temple of Apollo, whither he had fled in disgust at the sacrilegious murder of Achilles by Paris in the sanctuary.
Marx (Neue Jahrbiicher fir das klassische Altertum, 1904, p. 6 7368 5), Philoctetes did not appear in the original legend of Troy.
Just before the capture of the city, Paris, wounded by Philoctetes with one of the arrows of Heracles, sought the aid of the deserted Oenone, who had told him that she alone could heal him if wounded.
Some: light is thrown upon the lost plays by Dio Chrysostom, who in one of his discourses (52) describes his reading of the three tragedies, and in another (59) gives a prose version of the opening of the Philoctetes of Euripides.
It was he who suggested that Neoptolemus and Philoctetes should be fetched from Scyros and Lemnos to Troy, and he was one of those who advised the construction of the wooden horse.
Of the Aeschylean and Euripidean tragedies only a few fragments remain; of the two by Sophocles, one is extant, the other, dealing with the fortunes of Philoctetes before Troy, is lost.
