Oedipus enters the village of Colonus and sits down on a stone. They are approached by a villager, who demands that they leave, because that ground is sacred to the Furies, or Erinyes.

Sophocles' Philoctetes begins with their arrival on the island. Odysseus explains to Neoptolemus that he must perform a shameful action in order to garner future glory - to take Philoctetes by tricking him with a false story while Odysseus hides. Neoptolemus is portrayed as an honorable boy, and so it takes some persuading to get him to play this part. To gain Philoctetes's trust, Neoptolemus tricks Philoctetes into thinking he hates Odysseus as well. Neoptolemus does this by telling Philoctetes that Odysseus has his father's (Achilles) armor. He tells Philoctetes that this armor was his right by birth, and Odysseus would not give it up to him. After gaining Philoctetes' trust and offering him a ride home, Neoptolemus is allowed to look at the bow of Heracles.
