The origins of the flag and the oath
The idea of creating a flag for the Games had already been discussed in 1910 during a meeting of the IOC.
England's Theodore Cook had proposed a model at the meeting and a five-man commission was created to study the consideration, but without reaching a final decision.
During this period, Baron Pierre de Coubertin had created the five Olympic rings and displayed a 3m x 2m flag in "Bon Marche", a shop near his home in Paris.
In June, 1915, the flag was hoisted during a session of the IOC - celebrating its 20th year in existence. But it was in Antwerp that the flag made its true debut as the official flag of the Olympic movement.
In 1922 an embroidered flag was given to the IOC by the city of Antwerp as a souvenir - the idea being that the it would be passed on to the next host city of the Games. During the 1920 Games, the flag flew at the town hall in Antwerp.
Then, during an IOC session in Melbourne, the decision was taken to include the flag in the closing ceremony.
In 1960 in Rome, the Antwerp flag was handed over by the mayor of the town, passing through the hands of the IOC president, to the hosts of the next Olympiad.
The Olympic oath
The text for the oath consisted of the following: "In the name of all participants, I promise that we will take part in these Olympic Games in respecting, and abiding by the regulations in a sporting manner for the glory of sport and the honour of our countries".
In 1920, after discussing the content of the oath, the words "of our countries" was replaced by "of our teams".
In 1999, the global conference on doping defined a whole new chapter - making room therein for doping, intended for the attention of coaches and officials.
"In the name of all competitors, I declare and confirm that we have prepared for these Games in accordance with the regulations which govern them, in a veritable and ethically correct spirit of fair competition, and I promise that we will take part in the Olympic Games with regard to the ideal of fair-play for the glory of sport and the honour of our teams".
During the 1920 Games in Antwerp, the Belgian fencer Victor Boin, was given the task of reading the oath with his right hand raised.
