The Games were reputed to have originated as funeral games for Melicertes, instituted by Sisyphus, legendary founder and king ofCorinth, who discovered the dead body and buried it subsequently on the Isthmus. In Roman times, Melicertes was worshipped in the region. Theseus, legendary king of Athens, expanded Melicertes' funeral games from a closed nightly rite into fully-fledged athletic-games event which was dedicated to Poseidon, open to all Greeks, and was at a suitable level of advancement and popularity to rival those in Olympia, which were founded by Heracles. Theseus arranged with the Corinthians for any Athenian visitors to the Isthmian games to be granted the privilege of front seats. Another version states that Kypselos, tyrant of Corinth in the 7th century BC, returned to the Games their old splendour. If we are to accept the traditional date of the first Olympic Games, we can say that the first Isthmian Games would have been held in 582 BC. At least until the 5th century BC the winners of the Isthmian games received a wreath of celery; later, the wreath was altered such that it consisted of pine leaves. Victors could also be honored with a statue or an ode. Besides these prizes of honor, the city of Athens awarded victorious Athenians with an extra 100 drachmas.
History
From 228 BC or 229 BC onwards the Romans were allowed to take part in the games. The Games of 196 BC were used by Titus Quinctius Flamininus to proclaim the freedom of the Greek states from Macedonian hegemony. Compare Appian's account: Since the games' inception, Corinth had always been in control of them. When Corinth was destroyed by the Romans in 146 BC, the Isthmian games continued, but were now administered by Sicyon. Corinth was rebuilt by Caesar in 44 BC. Corinth recovered ownership of the Games at some point between 7 BC and AD 3. The Isthmian Games thereafter flourished until Theodosius I suppressed them as a pagan ritual.
Contests
Comparable to the Olympic Games. Among other competitions were:
Chariot races, men only
Pankration, men only
Wrestling, men only
Musical and poetical contests, in which women were allowed to compete.
Before the Games began, a truce was declared by Corinth to grant athletes safe passage through Greece. In 412 BC, even though Athens and Corinth were at war, the Athenians were invited to the games as usual.
