In 776 B.C. the first Olympic Games were held at the foot as Mount Olympus to honor the Greek's chief god, Zeus. The Greeks emphasized physical fitness and strength in their education of youth. Therefore, contests in running, jumping discus and javelin throwing, boxing, and horse and chariot racing were held in individual cities, and the winners completed every four years at Mount Olympus. Winners were greatly honored by having Olive wreaths placed on their heads and having poems sung about their deeds. Originally these were held as games of friendship, and any wars in progress were halted to allow the games to take place. The Greeks attached so much importance to these games that they calculated time in four-year cycles called "Olympiads" dating from 776.B.C.
