The Olympic flame:

The Olympic flame is a symbol carried over from the ancient Olympics, where a sacred (神圣的) flame burned at the altar(神坛)of Zeus throughout competition. It was finally reintroduced at the 1924 Amsterdam Games, and again burned in 1932.

Carl Diem, chairman of the organising committee for the 1936 Berlin Games, proposed that the flame be lit in Greece and transported to Berlin via a torch relay. The idea was adopted, and continued at every Olympic Games since 1952.

The flame is lit at the ancient site of Olympia by the natural rays of the sun reflected off a curved mirror. It is lit at a ceremony by women dressed in robes resembling those worn in ancient times, who then pass it to the first relay runner.

Olympic motto:

“Citius, altius, fortius” is a Latin phrase meaning “swifter, higher, stronger”, which Baron de Coubertin borrowed from Father Henri Martin Dideon of Paris. Dideon was headmaster of Arcueil College, and used the phrase to describe the athletic achievements of students at the school. He had previously been at the Albert Le Grand school, where the Latin words were carved in stone above the main entrance.

Olympic oath(宣誓)

“In the name of all competitors, I promise that we shall take part in these Olympic Games, respecting and abiding by the rules that govern them, in the true spirit of sportsmanship, for the glory of sport and the honour of our teams.”

Written by Baron de Coubertin, the oath is taken by an athlete from the host nation while holding a corner of the Olympic flag. The athletes’ oath was first taken by Belgian fencer Victor Boin at the 1920 Antwerp Games. A judge from the host country also speaks the oath, with slightly different wording.
