Athenian juries were drawn by lottery, from a group of hundreds of male-citizen volunteers; such a great jury usually ensured a majority verdict in a trial. Although neither Plato nor Xenophon of Athens identifies the number of jurors, a jury of 501 men likely was the legal norm. In the "Apology of Socrates" (36a–b), about Socrates’s defence at trial, Plato said that if just 30 of the votes had been otherwise, then Socrates would have been acquitted (36a), and that (perhaps) less than three-fifths of the jury voted against him (36b). Assuming a jury of 501, this would imply that he was convicted by a majority of 280 against 221.
