He was implicated during the Peloponnesian War in the mutilation of the Herms on the eve of the departure of the Athenian expedition against Sicily in 415 BC. Although he saved his life by turning informer, he was condemned to partial loss of civil rights and forced to leave Athens. He engaged in commercial pursuits, and returned to Athens under the general amnesty that followed the restoration of the democracy (403 BC), and filled some important offices. In 391 BC he was one of the ambassadors sent to Sparta to discuss peace terms, but the negotiations failed. Oligarchical in his sympathies, he offended his own party and was distrusted by the democrats.
