In Celtic mythology, the Unicorn of Scotland symbolized innocence and purity, healing powers, joy and even life itself, and was also seen as a symbol of masculinity and power.

During the reign of King James III (1466 - 1488), gold coins were introduced that featured a Unicorn, and at the time of King James VI of Scotland’s succeeding of Elizabeth I of England, and the resulting effective union of the two countries, the Scottish Royal Arms featured two unicorns as shield supporters. In a gesture of unity, King James replaced the one on the left with the English lion.
