HISTORY OF SWIMMING
Swimming has been known since prehistoric times. Drawings from the Stone Age were found in "the cave of swimmers" near Wadi Sora (or Sura) in the southwestern part of Egypt. Written references date from 2000 B.C., including Gilgamesh, the Iliad, the Odyssey, the Bible (Ezekiel 47:5, Acts 27:42, Isaiah 25:11), Beowulf, and other sagas. In 1538 Nicolas Wynman, German professor of languages, wrote the first swimming book, "Colymbetes". Competitive swimming in Europe started around 1800, mostly using breaststroke. The front crawl, then called the trudgen, was introduced in 1873 by John Arthur Trudgen, copying it from Native Americans. Swimming was part of the first modern Olympic games in 1896 in Athens. In 1902 the trudgen was improved by Richard Cavill, using the flutter kick. In 1908, the world swimming association, Federation Internationale de Natation de Amateur (FINA), was formed. Butterfly was first a variant of breaststroke, until it was accepted as a separate style in 1952.
Ancient Times
Drawings from the Stone Age were found in "the cave of swimmers" near Wadi Sora (or Sura) in the southwestern part of Egypt near Libya. These pictures seem to show breaststroke or dog paddle, although it may also be possible that the movements have a ritual meaning unrelated to swimming. This cave is also featured in the movie The English Patient. An Egyptian clay seal dated between 4000 B.C. and 9000 B.C. shows four swimmers who are believed to be swimming a variant of the front crawl.
Written references date back to 2000 B.C. including Gilgamesh, the Iliad, the Odyssey, the Bible (Ezekiel 47:5, Acts 27:42, Isaiah 25:11), Beowulf, and other sagas, although the style is never described. There are also many mentions of swimmers in the Vatican, Borgian and Bourbon codices.
