Other forms: unicorns
A unicorn is a mythical horse-like creature which has one horn on its forehead. During the Middle Ages, a unicorn horn was said to have magical healing properties.
Unicorns show up in many cultures' traditions of folklore and mythology, reaching as far back as Bronze Age civilizations and ancient Greece. Usually, unicorns are presented in art and stories as looking just like horses — or sometimes goats — aside from their long, spiraling horn. The root of the word unicorn is the Latin adjective unicornis, "having one horn," from uni, or "one," and cornus, "horn."
