The athletic festivals upon which our modern Olympic games are based were held at Olympia between 776 BC and AD 393. According to Greek legend, they had been held during the early Bronze Age as well, as early as the 10th or 11th century BC. The best records date to the revival of the Festival of Zeus in 776 BC. Games were held every four years, at the beginning and middle of the so-called "Great Year," a calendric trick used to rectify the differences in solar and lunar years.

entrance, where athletes would parade in at the start of the games.
