History of the Peloponnesian War

There had been one Cylon an Athenian, a man that had been victor in the Olympian exercises, of much nobility and power amongst those of old time, and that had married the daughter of Theagenes, a Megarean, in those days tyrant of Megara.

To this Cylon asking counsel at Delphi the God answered that on the greatest festival day he should seize the citadel of Athens.
