Olympiad แปลว่า

"The reckoning by olympiads, or any other fixed æra, was not yet in uſe among the Greeks. The Arundelian marbles were compoſed ſixty years after the death of Alexander the Great, and yet mention not the olympiads, nor any ſtanding æra, but reckon backward from the time then preſent. In the next olympiad, Timæus Siculus wrote a hiſtory down to his own times, according to the olympiads."

"[N]ot Hellas can unroll / Through her olympiads two such names, though one / Of hers be mighty;—and is this the whole / Of such men's destiny beneath the sun?"

"The olympiads, or quadrennial athletic meetings of ancient Greece, were held in such national renown, that they served as historical epochs for the chronological establishment of events. […] The victor in each race overcame the opponents who contested with him shoulder to shoulder; but there could be no means to determining whether the victor of a given event in one olympiad excelled the victor in other olympiads."
