The remodelled festival was a trieteris, held in the spring of the second and fourth years of each Olympiad. The programme was a varied one, including, besides athletics and horse-races, musical competitions, and possibly a regatta. The presidency of the festival belonged to the Corinthians. Whether its establishment as a Panhellenic festival was due to the tyrant Periander or expressed the joy of the people at their liberation from his rule, the evidence does not allow us to determine. The latter seems to me more probable. The great tyrant, laid by his victory in the chariot-race at Olympia, and by costly offerings to Olympia and Delphi, tried to win the support of the authorities at these places, and it may well be that the founding of a rival festival marked the popular reaction against his policy. Be this as it may, the establishment of the Isthmia is another sign of the great national movement towards unity. Tyrants recognized and tried to utilize the movement for their own advantage. But Panhellenism was independent of tyrants; it was a spontaneous movement of the people, and it need cause no surprise that one Panhellenic festival should owe its origin to a tyrant, another to the people. A similar doubt attaches to the last of the Greek festivals, the Nemea. The cypress grove of Nemea, where stood the temple of the Nemean Zeus, lay in a secluded valley among the hills, half-way between Phlius and Cleonae. Here under the presidency of the latter state local games had long been celebrated. They were said to have been founded by Adrastus as funeral games in honour of the child Opheltes, who, having been left by his nurse in the grove, had been devoured by a serpent. According to another story, they were founded by Heracles after his slaying of the Nemean lion, and by him dedicated to Zeus. They were reorganized in the year 573 B.C. as a trieteris, and took place like the Isthmia in the second and fourth year of each Olympiad, probably at the very beginning of the Olympic year in July. The prize was a wreath of fresh celery, but was said to have been originally a wreath of olive. As at Olympia, the managers of the games bore the title of Hellanodicae. As at Olympia, the contests were until later times purely athletic and equestrian. The striking resemblances to Olympia are clearly due to Dorian influence, and may perhaps help us to understand how it was that, within a few years of the founding of the Isthmia, a second Panhellenic festival was established in its immediate neighbourhood.
