Crito
The dialogue takes place in Socrates' prison cell, where he awaits execution. He is visited before dawn by his old friend Crito, who has made arrangements to smuggle Socrates out of prison to the safety of exile. Socrates seems quite willing to await his imminent execution, and so Crito presents as many arguments as he can in order to persuade Socrates to escape. On a practical level, Socrates' death will reflect badly on his friends--people will think they did nothing to try to save him. Also, Socrates should not worry about the risk or the financial cost to his friends; these they are willing to pay, and they have also arranged to find Socrates a pleasant life in exile. On a more ethical level, Crito presents two more pressing arguments: first, if he stayed, he would be aiding his enemies in wronging him unjustly, and would thus be acting unjustly himself; and second, that he would be abandoning his sons and leaving them without a father.
Philoctetes (Sophocles play)
When Heracles was near his death, he wished to be burned on a funeral pyre while still alive. In the "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.
