Unicorn means “one horn.” Most often unicorns are depicted as a white horse-like creature with a single horn growing from its forehead. Sometimes unicorns are depicted as a deer, ass or goat with a single horn. The horn is often depicted as long and straight, marked with spiral striations along its length.
Unicorns are also often depicted as having cloven hooves like cattle, deer, or goats. So while the rest of their bodies may be horse-like, they have the hooves of a biungulate, not the ungulate (single-toed) hooves of a horse. They are often depicted with similar coat colors to horses, but most often they are described as being white.
Unicorns have supposedly been endowed with many magical qualities. Unicorn tears and blood are said to be healing, powder of unicorn horn is said to be an antidote for poison, and Harry Potter’s wand contained a strand of unicorn tail hair. Unicorns are said to be difficult to catch—not unlike some horses who don’t like to be caught—and in many mythologies, can only be tamed by young maidens. They are a symbol of ferociousness, freedom, power, and speed and appear on many coats of arms and emblems.
