http://stores.ebay.com/Metal-Art-Manifestations - In heraldry, a unicorn is depicted as a horse with a goat's cloven hooves and beard, a lion's tail, and a slender, spiral horn on its forehead. Whether because it was an emblem of the Incarnation or of the fearsome animal passions of raw nature, the unicorn was not widely used in early heraldry, but became popular from the 15th century. Though sometimes shown collared, which may perhaps be taken in some cases as an indication that it has been tamed or tempered, it is more usually shown collared with a broken chain attached, showing that it has broken free from its bondage and cannot be taken again.
