The mythical unicorn is one of Scotland's official symbols. When the Crown of England and the Crown of Scotland were merged into a single British monarchy by the Acts of Union in 1707, the coat of arms for the newly formed Great Britain featured the English lion and the Scottish unicorn in equally supportive roles.
Our Canadian coat of arms features the same lion and unicorn imagery, since Britain's monarch is also the Canadian head of state.
The imposing main entrance of Canada's parliament buildings in Ottawa is flanked by larger-than-life statues of the heraldic lion and unicorn:
I suppose the lion is roaring and the unicorn is . . . whinnying? I don't know what sound unicorns are traditionally supposed to make but something horse-like would seem to be most likely.
These serious unicorns represent purity of heart, freedom and the ancient right of kings. They do not fart rainbows and glitter like today's silly unicorns. Sometimes it's important to remember their original dignity and symbolism.
