Socrates (film)
His enemies, led by a young man named Meletus, accuse him in court, arguing that the philosopher preaches crazy doctrines to the youth, and does not believe in the gods, but demons. Socrates makes his "apology" (i.e., legal defense), but the citizens are against him; so Socrates is sentenced to death, and held in prison, awaiting execution. His disciples are desperate, and one of them, Crito, tries to help him by encouraging him to flee. Socrates rejects this idea, saying he must obey the rulers of the city. Socrates then resolves to die, and dies as soon as he is forced to drink hemlock.
Memento mori
Plato's "Phaedo", where the death of Socrates is recounted, introduces the idea that the proper practice of philosophy is "about nothing else but dying and being dead". The Stoics of classical antiquity were particularly prominent in their use of this discipline, and Seneca's letters are full of injunctions to meditate on death. The Stoic Epictetus told his students that when kissing their child, brother, or friend, they should remind themselves that they are mortal, curbing their pleasure, as do "those who stand behind men in their triumphs and remind them that they are mortal"
