[Greek heroic] Cercyon was the son of Poseidon. Cercyon was king of Elusis. Cercon was a very strong man and he took advantage of this. He would wrestle Greek by-passers to their deaths. Incentive for these people was that if they beat Cercyon they also won his kingdom. Nobody could beat him until Theseus came, beat Cercyon, and won his kingdom.
