The war, however, broke out afresh and lasted for six years, at the end of which, in 582, the festival was finally reorganized out of the spoil of Crisa as a pentaëteris, and placed under the control of the Amphictyons. The year 582 dates as the first Pythiad, and from this time the festival was held every fourth year, in the August of the third year of each Olympiad. The valuable prizes which had been offered of old were abolished, and in their place was substituted a crown of bay leaves plucked from the Vale of Tempe. The somewhat scanty details which we possess as to the festival and its history will be discussed in a later chapter. For the present it is sufficient to note one significant fact: the chariot-race which had been omitted in 590 was introduced in 582, and the first victor was Cleisthenes of Sicyon himself. The plains of Sicyon were admirably adapted for breeding horses, a pursuit which afforded its tyrants a ready means of increasing and displaying their wealth. Myron had already gained a victory in the chariot-race at Olympia, and his grandson Cleisthenes, shortly after his Pythian success, secured the same honour on the occasion when he issued his invitation to the suitors for the hand of Agariste. At Sicyon itself he commemorated the part which he had played in the Sacred war by a splendid colonnade built out of the spoils of Cirrha, and at the same time he reorganized as a local Pythia an ancient festival connected with the Argive hero Adrastus, whose memory he delighted to insult.[73] We may therefore safely regard the introduction of the chariot-race at Delphi as due to the tyrant’s influence, and the remodelling of the festival as part of his pushing Panhellenic policy.
