A dynamic depiction of the Unicorn of Scotland leaping over the shield of Scotland which bears a lion.

The unicorn is a legendary creature that has been described since antiquity as a beast with a single large, pointed, spiraling horn projecting from its forehead. In European folklore, the unicorn is often depicted as a white horse-like or goat-like animal with a long horn and cloven hooves (sometimes a goat's beard). In the Middle Ages and Renaissance, it was commonly described as an extremely wild woodland creature, a symbol of purity and grace, which could only be captured by a virgin.

From the end of the 16th century, two unicorns were adopted as the supporters of the Scottish Royal Arms. James VI of Scotland became James I of England after he succeeded the childless Elizabeth I in 1603, thus uniting the thrones for the first time. The new king took the Lion of England and one of the Scottish unicorns as supporters for the Royal Arms, and they have remained in place ever since. The origin of the unicorn as a regular supporter of the Scottish arms is unknown, but since the 15th century it has been associated with Scotland, where it was struck on gold coins called “unicorns” for their design of a unicorn supporting the Scottish shield.

The Unicorn of Scotland, milky-white in colour with golden hooves, horn, and mane, has always had a coronet around its neck like a collar, with a gold chain attached. It’s thought that the chains were to show a great beast tamed to serve the king. Certainly, as with most chained beasts in heraldry, its strength is emphasised rather than diminished by the shackles.
