A unicorn is a legendary creature typically depicted as a horse-like animal with a single horn on its forehead. It appears in ancient mythologies and later became a major symbol of purity in medieval Europe.

Origins

Unicorn traditions appear in ancient Mesopotamian art and in early references from India, China, and Greece. The Greek writer Ctesias described a one-horned animal from India in the 4th century BCE, one of the earliest literary accounts.

Medieval and Renaissance symbolism

In medieval Europe, the unicorn was closely associated with purity, grace, and virginity. It also became a Christian symbol in art and literature, often linked to the Virgin Mary, reinforcing its reputation as a creature of virtue.

Today, unicorns are widely used in fantasy, children's media, and pop culture. The term also has specialized modern uses – in venture capital for a startup valued at one billion dollars or more, and in Canada's own startup ecosystem. The unicorn is also a national symbol of Scotland.
