The games were opened to all Greeks. There was no exemption—except for women.
There was a rigorous law that if any woman was found so much as to have passed the river Alpheus during the Olympian games, she was to be thrown headlong from a rock; and this continued until Pherenice, who went disguised to attend on her son while he wrestled, was apprehended and tried. She was acquitted, out of respect to her father, brothers and son, who had all won first prizes at the games. Afterward women were admitted, and then even contended at the games. Cynisca, the daughter of Archidamus, was the first woman who was crowned at Olympia; and after her, many women, especially those of Macedonia, were crowned as the winners of prizes.
The Romans also excluded women; but Augustus allowed them to witness the gladiatorial fights, and assigned them a place in the highest seats of the amphitheatre.
Rich and poor among the Greeks were allowed to enter on the same terms. The preparatory course was long, arduous, and not to be escaped. Every competitor was obliged to give ten months' training before he was allowed to enter the games. The public gymnasium was at Elis, and thither the competitors had to go for the ten months of training.
