Oetzi, a 5-foot-3-inch-tall iceman, believed to have lived 5,300 years ago is Europe's oldest known mummy, having been found in Italy's Oetztal Alps on September 19, 1991. According to scientists, Oetzi possibly died aged 45 from an arrow wound after which his body got preserved in ice and has since contributed to present knowledge of Neolithic mankind's lifestyle.
