Interesting fact:

The first painting of a unicorn is estimated to be somewhere between 6,000 and 10,000 years ago. Over the millennia, beliefs about unicorns, as well as what they symbolize, has changed. For example, in medieval times, a unicorn horn was said to have magical healing powers. However, a unicorn's bite was believed to be deadly. Whatever the belief, the unicorn has remained a most enchanting and elusive creature.
