Thus spake Pericles. The Athenians, liking best of his advice, decreed as he would have them, answering the Lacedaemonians according to his direction, both in particulars as he had spoken and generally, that they would do nothing on command, but were ready to answer their accusations upon equal terms by way of arbitrament. So the ambassadors went home, and after these there came no more.
These were the quarrels and differences on either side before the war, which quarrels began presently upon the business of Epidamnus and Corcyra. Nevertheless there was still commerce betwixt them, and they went to each other without any herald, though not without jealousy. For the things that had passed were but the confusion of the articles and matter of the war to follow.
The war between the Athenians and the Peloponnesians beginneth now from the time they had no longer commerce one with another without a herald, and that having once begun it they warred without intermission. And it is written in order by summers and winters according as from time to time the several matters came to pass.
The peace, which after the winning of Euboea was concluded for thirty years, lasted fourteen years. But in the fifteenth year, being the forty-eighth of the priesthood of Chrysis in Argos, Aenesias being then ephor at Sparta and Pythadorus, archon of Athens, having then two months of his government to come, in the sixth month after the battle at Potidaea and in the beginning of the spring, three hundred and odd Thebans led by Pythangelus the son of Phyleides and Diemporus the son of Onetoridas, Boeotian rulers, about the first watch of the night entered with their arms into Plataea, a city of Boeotia and confederate of the Athenians.
