415 BC, he was accused of impiety, and he thought it best to escape Athens to avoid prosecution, and classical sources speak of a reward for either catching or killing him.[7] Religion may have been only the pretext for the accusation, for being a Melian made him an object of suspicion with the people of Athens. In 416 BC, Melos had been conquered and cruelly treated by the Athenians, and it is not at all impossible that Diagoras, indignant at such treatment, may have taken part in the party-strife at Athens, and thus have drawn upon himself the suspicion of the democratic party. Diagoras subsequently went to Corinth, where, as the Suda states, he died.
