The Olympic games
The first Olympic Games were created in Olympia but their origines are not very known. They took place during 12 centuries before Theodose 1st forbid them.
The Olympia's games take place every four years so the time is not counted in year but in olympiad (which is equal at four years). The Olympia's games are originally of the Panhellenic games which coat the Olympia's game which take place every four years,
The Delphi's games which take place every third year of the olympiad, the Corinth's isthmus's games and the Nemea's games which take place every two years.
If womens were expelled of the Panhellenic games, they could do the Hera's games (who is the Zeus's wife) every four years. They represent the victory like a women with wings named Niké (means victory in greek), she brought the crown to the winner.
