History of Swimming

From Answers.com

Did you know that swimming has been around 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, Beowulf, and other sagas.
