Olympic Games were instituted at Olympus, in honour of the Greek-god Zeus. These festivals included competitions in literature, art, drama, music and gymnastics, and they were continued, with intervals, from 776 B.C. to 394 A.D. The athletic part of the Games was revived in the 19th Century. The Ganes, as known at present, were first played in Athens in 1896, and subsequently, at intervals of four years, in different cities of the world, barring the years 1916, 1940 and 1944, when the World Wars intervened.
