The festival in honor of Olympian Zeus recurred every four years, at the time of the full moon following the summer solstice. Sacred heralds carried to all parts of the Greek world the official message announcing the festival, and a sacred truce was declared for a sufficient length of time to allow all desirous of doing so to attend the gathering and to return home. As the great day approached, men and youths, matrons and maidens, set out to take part in or to witness the various features of the festival. Cities sent sacred embassies, or _theoriae_, resplendent in purple and gold, bearing offerings to the god. Artists and poets, merchants and manufacturers, found in this gathering of the Greeks a great mart in which they could make known their talents or their wares and receive lucrative orders, the former for a statue or an ode, the latter for the sale of their merchandise. Tents stood in rows upon the plain, and everywhere were scenes of busy traffic or of social entertainment. We are not concerned here with the various exercises that constituted the festival, nor with the games which were celebrated in the stadium, nor with the horse and chariot races in the hippodrome, except in so far as women were participants; and their part was but slight. When the games were held, a priestess of Demeter was present, seated on an altar of white marble opposite the umpires' seats, but she was the only woman to whom this privilege was granted. While their loved ones were contending in the stadium, mothers and wives and sisters had to remain on the southern bank of the Alpheus. Only one instance is recounted where this rule was broken. "Pherenice, daughter of a celebrated Rhodian wrestler, whose family boasted that they were descended from Hercules, could not bear to leave her son while the contest was going on, and disguising herself as a man, and pretending to be a teacher of gymnastics, she mingled with the groups of gymnasts. When her son was proclaimed victor, however, her feelings carried her away, and forgetful of prudence she rushed to embrace her child. In her haste her robes became disordered, and her sex was revealed. The law was explicit: every woman found within the sacred precinct was condemned to death. Nevertheless, the judges acquitted her, in recognition of the fame her family had won; but to prevent any repetition of the occurrence, the masters, as well as their pupils, had thenceforth to present themselves naked."
