The Fountain of Youth is a spring that supposedly restores the youth of anyone who drinks or bathes in its waters. Tales of such a fountain have been recounted across the world for thousands of years, appearing in writings by Herodotus (5th century BC), the Alexander romance (3rd century AD), and the stories of Prester John (early Crusades, 11th/12th centuries AD). Stories of similar waters were also evidently prominent among the indigenous peoples of the Caribbean during the Age of Exploration (early 16th century), who spoke of the restorative powers of the water in the mythical land of Bimini and others. Based on these many legends, explorers and adventurers have long looked for the elusive Fountain of Youth or, at least, some remedy to aging, which was most often associated with magic waters. These waters were not necessarily a fountain but might have been a river, a spring, or any other water source that was said to reverse the aging process and cure sickness when drank or bathed in.
