Many of the ancient drawings and paintings come from what is now Italy. The oldest date back 2,600 years, belonging to the Etruscans at Tarquinia. An ancient tomb in Greece depicts swimming and diving scenes and dates back 2,500 years.

Written testament to early swimming falls within the past 3,000 years. The Bible, the Iliad, the Odyssey all contain references to swimming. Thucydides noted the activity in scripts that are 2,400 years old.

Many of the world's ancient civilisations swam, including the Egyptians, the Phoenicians, Persians, Romans and Greeks. Plato once declared that anyone who could not swim lacked a proper education, and Julius Caesar was known for his swimming prowess.

In terms of competitions, the Japanese can point to evidence that races were held 2,000 years ago. The "modern" sport can be traced back to English clubs in the 1830s, when breaststroke was the most common manner of moving through water. Names such as Otter Swimming Club in London and the Leander Swimming Club date back to the 19th century.

Yet even there, it was a little like reinventing the wheel. When a race was held in London in 1844, invitations were sent far and wide - even to NativeAmerican. Several turned up, and shocked crowds by winning comfortably by using a windmill action with their arms that was not too far removed from today's front crawl, the stroke used in modern freestyle races.

Despite the Indian "innovation" (some of those ancient bas-reliefs indicated that overarm actions may have been used thousands of years ago), breaststroke remained the most commonly used stroke until the late 19th century, and in terms of leisure swimming - take a look along the lanes of your local pool - might still be said to be the easiest and therefore most popular stroke.

Captain Matthew Webb swam breaststroke when he became the first person to swim across the English Channel in 1875. A contemporary of Captain Webb was J. Arthur Trudgen, an English swimmer and coach who lent his name to the Trudgen stroke, which used a breaststroke kick but an overarm action that he had seen used by South American Indians. The Trudgen was adopted around the world but then adapted by Fred Cavill, an Englishman who had emigrated to Australia. Cavill had developed the technique by watching South Sea Islanders. Instead of the breaststroke kick, Cavill used a "flutter-kick" like that seen among today's front crawl specialists such as the Thorpe, whose massive size-16 feet act like propellers at the end of his legs. The technique became known as Australian crawl, a term that lasted up to the days of Murray Rose and John Konrads in the 1950s and 60s before simply becoming front crawl.
