In 1991, two German tourists were hiking in the Otzal Alps, on the Italian side of the border between Italy and Austria, when they happened upon what appeared to be a corpse buried beneath the ice. Astounded, they alerted authorities. It was found that Otzi (as the body was named) was a 45-year-old traveler himself who was more than 5,300 years old. It was likely he faced what investigators believe was a violent death. On his body were more than 50 tattoos, jewelry, and weapons, all of which gave researchers clues into the lives of our copper age ancestors.
