Text #8865Chronology of the Ancient World .
Retrospectively set as the first Olympiad. The history of the Olympic Games is believed to reach as far back as the 13th century BC. Beginning with Ephorus, it was used as a calendar epoch. By this reckoning, the first Olympiad lasted from the summer of 776 BC to that of 772 BC. Example: Olympiad 140, year 1 = 220/219 BC; year 2 = 219/218 BC; year 3 = 218/217 BC; year 4 = 217/216 BC. The sophist Hippias was the first writer to publish a list of victors of the Olympic Games, and by the time of Eratosthenes, it was generally agreed that the first Olympic games had happened during the summer of 776 BC. The combination of victor lists and calculations from 776 BC onwards enabled Greek historians to use the Olympiads as a way of reckoning time that did not depend on the time reckonings of one of the city-states. The first to do so consistently was Timaeus of Tauromenium in the third century BC. Nevertheless, since for events of the early history of the games the reckoning was used in retrospect, some of the dates given by later historian for events before the 5th century BC are very unreliable. In the 2nd century AD, Phlegon of Tralles summarised the events of each Olympiad in a book called Olympiads, and an extract from this has been preserved by the Byzantine writer Photius. Christian chroniclers continued to use this Greek system of dating as a way of synchronising biblical events with Greek and Roman history. In the 3rd century AD, Sextus Julius Africanus compiled a list of Olympic victors up to 217 BC, and this list has been preserved in the Chronicle of Eusebius.
