"Every four years heralds traveled throughout the ancient Greek world proclaiming a sacred truce, affording safe passage through any state for all travelers to and from the games. All Greeks were invited to attend or compete in the great festival and games at the sanctuary of Zeus at Olympia. And come they did, from 776 B.C. (the traditional date of the first Olympiad) to at least the late fourth century A.D., making the games the most enduring of Greek institutions. These panhellenic gatherings were vital to Greek ethnicity. They were multinational, but only free, male Greeks could compete. At Olympia visitors and participants from Greek city-states throughout the Mediterranean shared a common culture in which religious piety and enthusiasm for sport were of pivotal importance. By the mid-sixth century Olympia had emerged as the pinnacle of a circuit of four great panhellenic sacred 'crown' games with wreaths awarded to the victors. The others, at the sanctuaries of Delphi, Isthmia, and Nemea, were held sequentially, with at least one festival each year culminating in the finale at Olympia. Named after the winner in the men's sprint race, the Olympiads provided a common chronology at a time when each city-state had its own calendar."
