The Athenian Philosopher Who Drank Hemlock in 399 BCE After an Athens Jury Sentenced Him to Death by 280 to 220 Votes

Socrates of Athens (c. 470-399 BCE) was 70 years old in 399 BCE. He had spent approximately 40 years conducting public philosophical conversations in the Athenian marketplace and gymnasia. He left no written work. Everything we know about him comes through the writings of his students — principally Plato and Xenophon — and the hostile comic portrayal in Aristophanes’ Clouds (423 BCE).

The political context of the 399 BCE trial was the substantial aftermath of the Peloponnesian War (defeat in 404), the brief tyranny of the Thirty (404-403), and the restoration of Athenian democracy (403). Several of Socrates’ former students — including Critias, the leader of the Thirty — had been on the wrong side. The 403 amnesty had legally precluded prosecution for the political events themselves, but had not precluded prosecution under religious-impiety statutes for the philosophical practice that had produced the bad students.

The charges

The formal indictment, drafted by Meletus, Anytus, and Lycon, charged Socrates with:

— Not believing in the gods of the Athenian state — Introducing new divine beings — Corrupting the young

The trial was held before a dikastērion of approximately 500 randomly-selected Athenian male citizens. Each side spoke for approximately 90 minutes. The jury voted by depositing bronze tokens.

The verdict was 280 to 220 for conviction — a majority of 60.

The penalty phase

Athenian capital trials had a two-phase structure. Once the verdict was returned, the prosecution proposed a penalty and the defence proposed a counter-penalty. The jury voted between the two options without further deliberation.

The prosecution proposed death. The convention was for the defence to propose substantial exile, which the jury would normally accept. Socrates instead proposed that he should be honoured at public expense as a public benefactor. He then revised the proposal under pressure from Plato and other friends to a small fine of 30 minae (about a year’s income for a skilled craftsman) which they would pay on his behalf.

The jury voted for death by a wider margin than the conviction verdict — Diogenes Laertius gives 360-140. The combination of conviction by 60 and death-vote by 220 indicates that approximately 80 jurors who had voted to acquit changed their vote on the penalty after hearing the substantial defence’s counter-proposal.

The hemlock

Athenian executions were normally substantially carried out within 24 hours. Socrates’ execution was delayed by approximately a month because of the religious calendar — the annual Athenian state ship to Delos had departed the day before the trial and substantial executions were prohibited during its absence.

The delay is the substantial setting of Plato’s Crito (Socrates refuses Crito’s offer to bribe the jailers and escape) and Phaedo (the philosophical conversation at the deathbed). The Phaedo account is the substantial principal source for the manner of the death.

Socrates drank a substantial cup of crushed hemlock (Conium maculatum) prepared by the prison’s attendant. He walked around the cell until his legs began to feel substantial heavy. He lay down on the bed. The numbness substantially progressed upward through his body. His last reported words were to his friend Crito: “Crito, we owe a cock to Asclepius — pay the debt and do not forget.”

Asclepius was the substantial Greek god of healing. The substantial conventional reading of the last words — the substantial debt that one paid to Asclepius was for substantial recovery from illness — is that Socrates was substantially expressing that death was a substantial cure for the substantial illness of being alive. The substantial alternative readings — that the substantial words were a substantial private joke, or that they referred to a substantial recent recovery of a substantial friend — are also defensible.

He was 70.

What followed

Plato’s Apology (the substantial account of the defence speech) and Phaedo (the death scene) substantially established the substantial canonical Western philosophical image of the substantial philosopher as the substantial martyr to truth against the substantial democratic mob. The substantial image has been substantially central to substantial Western political philosophy from the substantial 4th century BCE to substantial the present.

Athens had no further substantial philosophical-impiety prosecutions for the substantial subsequent 770 years. The substantial Athenian schools — Plato’s Academy (founded 387 BCE), Aristotle’s Lyceum (335 BCE), the substantial Stoa and the substantial Epicurean Garden — substantially continued without further substantial state interference until the substantial closure of the Academy by Justinian in 529 CE.
