History of the Peloponnesian War

When the Lacedaemonians, then, were in such a state of variance with the Athenians, those at Athens, again, who wished to do away with the treaty, were immediately urgent against it.

Amongst others who were so was Alcibiades son of Clinias, a man who in age was still at that time a youth, (as he would have been thought in any other state,) but honoured on account of the nobility of his ancestors. He considered that it was really better to side with the Argives; though he also opposed the treaty in the bitterness of wounded pride, because the Lacedaemonians had negotiated it through the agency of Nicias and Laches, having overlooked him on account of his youth, and not having shown him the respect suitable to the old connexion of his family as their proxeni, which, having been renounced by his grandfather, he himself thought to renew by showing attention to the prisoners taken in the island.

Considering himself therefore to be in every way slighted by them, he both spoke against the treaty in the first instance, saying that the Lacedaemonians were not to be depended upon, but were only making a treaty in order that by so doing they might deprive Athens of the Argives. and again come against them when left alone; and at that time, when this difference had arisen, he immediately sent to Argos on his own account, urging them to come as quickly as possible with proposals for alliance, in company with the Mantineans and Eleans, since it was a fine opportunity, and he would co-operate with them to the utmost.
