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.
Impiety
The issue of impiety in antiquity is very controversial because of the anecdotal nature of extant sources. A number of Athenian men, including Alcibiades, were sentenced to death for impiety in 415 BC, most of whom fled Athens before execution (Andocides was later charged in 400 or 399 BC in reference to these events). Most famously, the philosopher Socrates was executed for impiety (as well as corrupting Athenian youth) in 399 BC. An Athenian philosopher Anaxagoras taught that the sun and the stars were fiery stones whose heat we did not feel because of their distance, and was allegedly accused of impiety in Athens. Diagoras of Melos was reportedly accused of atheism and had to flee Athens after being charged with impiety for revealing the content of the Eleusinian mysteries to the uninitiated. Philosophers Aristotle and Theophrastus might have been accused of impiety as well.
