The image of the Unicorn is a white horse with a long spiral golden or white horn on its forehead. In medieval times, it was believed that the unicorn was the size of a donkey or a goat. It was white, with the head of a deer, the body of a horse, a lion's tail, a goat's beard, and split hooves. It was a symbol of purity and faith, with the belief that no one could tame it.
