The unicorn has been used as a heraldicc motif, appearing on the national arms and coins of Scotland. The royal throne of Denmark was made of "unicorn horns," which were actually narwhal tusks. The same material was used for ceremonial cups because the unicorn's horn was believed to neutralize poision.
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 embelm of th eIncarnation or of the fearsome animal passions of raw nature, the unicorn was not widely used in early heraldry. It only became popular around the fifteenth century, usually collared, an indication that its nature had been tempered.
Scotland and the United Kingdom use the unicorn in their heraldry. Two unicorns support the Scottish arms, and a lion and a unicorn support the United Kingdom arms. The arms of the Society of Apothecaries in London has two golden unicorn supporters.
