THE Olympic Games is the most important sporting event in the world. Every country is invited to take part. In the Beijing Olympics in 2008 there were athletes from 204 countries.
The original Olympic Games were first recorded in 776BCE and were held in Olympia, Greece. The first modern day Olympics were held in Athens in 1896.
The Olympic torch of fire is carried from Olympia to the host city by a series of relay runners as a reminder of the Games' origins. This fiery torch is then used to light the Olympic flame in the stadium. - The New Children's Encyclopedia, Dorling Kindersley
