Today, unicorns are creatures of fairy tales. But thousands of years ago, people believed these creatures were real, living animals. In Europe, Greek travelers told tales of unicorns, and naturalists described them in the books they wrote. Thousands of years earlier, Chinese were telling their own tales of the unicorn. In both Asia and Europe, people believed the unicorn was an elusive, powerful, and peaceful creature.
