The athletes' oath
One of the most important moments at the opening ceremony of the Olympic Games is the athletes' oath. After the official opening by the head (usually) of the state that hosts the Games and after the parade of the athletes by national delegation, an athlete of the host country swears the oath, holding with one hand one of the corners of the Olympic flag. Like the Olympic flag, the athletes' oath was first presented at the Games of Antwerp in 1920, at the beginning of a period (the interwar period) when the procedures of forming and crystallizing the symbols (e.g. flag, flame) and rituals (e.g. lighting ceremonies, oath) that characterize the Games were intensified. The Olympic oath, which was composed by Pierre de Coubertin, was first heard by the Belgian fencer and water polo player Victor Boin on 14 August 1920 and included the following: "In the name of all competitors, I promise that we shall take part in these Olympic Games, respecting and abiding by the rules which govern them, in the true spirit of sportsmanship, for the glory of sport and the honour of our teams".
Abiding by the rules naturally bears on the procedures of uniformity in the rules of each event, which intensified especially after the Games of 1912. At the same time that reference, with the symbolic weight that every oath ceremony carries, constitutes an indirect commitment of the participant athletes as to the amateur nature of their involvement in sport. That issue was a primary concern for the IOC members since the Olympic institutions were beginning to shape and for many decades. It is not a coincidence that the athletes' oath and, hence, the ceremonial confirmation of amateurism first appeared in 1920, more precisely at the first Olympic Games that were organized after Jim Thorpee was deprived of his medals. Several decades later, at the Olympic Games of 2000, at a time when the approach to professionalism had transformed radically and the major problem now was doping, the IOC modified the athletes' oath adding the phrase "committing ourselves to a sport without doping and without drugs".
Since 1972, apart from the athletes' oath, the opening ceremony includes the oath of the umpires and judges, which is quite similar to the athletes' oath. Besides, in 1972 it was the first time that a woman, the long jumper Heidi Schuller, swore the oath on behalf of all the competitors. It should also be noted that in 1988 the oath was sworn for the first time by two athletes, Sohn Mi Nai and Huh Jae. Two athletes swore the Olympic oath in 1956 as well, since the equestrian events did not take place in Melbourne but in Stockholm. Therefore, apart from John Landy, a track and field athlete, in Stockholm the oath was sworn by Henry St. Cyr on behalf of the athletes participating in equestrian events.
