How did the rewards of athletic competition change over the years? How did it change who could compete?
What kinds of honors did Olympic winners receive?

At ancient Greek sports festivals it was the custom to give ribbons to winning athletes. Later, at the awards' ceremony, the athlete received a wreath of leaves such as olive, laurel or wild celery leaves, depending on the festival. The identity of the athlete and the event he won are not known. Athletes are selected by their respective NOCs, who are responsible for supporting them and entering them for the Games. The IOC sends out invitation letters to all NOCs one year before the Opening Ceremony and those NOCS then submit entries for the Games who are then approved or otherwise by the IOC. They got The Olympic Order award for winning.
