Volley gun
The Ribauldequin was a medieval version of the volley gun. It had its barrels set up in parallel. This early version was first employed during the Hundred Years' War by the army of Edward III of England, in 1339. Later on, the late Swiss army employed it.
Volleyball at the Summer Olympics
The history of Olympic volleyball can be traced back to the 1924 Summer Olympics in Paris, where volleyball was played as part of an American sports demonstration event. Its addition to the Olympic program, however, was given only after World War II, with the foundation of the FIVB and of some of the continental confederations. In 1957, a special tournament was held during the 53rd IOC session in Sofia, Bulgaria, to support such request. The competition was a success, and the sport was officially introduced in 1964. The Olympic Committee initially dropped volleyball for the 1968 Olympics, meeting protests.
