unicorn

n. mythical horse-like creature with one spiraling horn growing from its forehead

The unicorn (from Latin unus 'one' and cornu 'horn') is a legendary creature.Though the modern popular image of the unicorn is sometimes that of a horse differing only in the horn on its forehead, the traditional unicorn has a billy-goat beard, a lion's tail, and cloven hooves - these distinguish it from a horse. Marianna Mayer has observed (The Unicorn and the Lake), "The unicorn is the only fabulous beast that does not seem to have been conceived out of human fears. In even the earliest references he is fierce yet good, selfless yet solitary, but always mysteriously beautiful. He could be captured only by unfair means, and his single horn was said to neutralize poison."

There it is usually depicted as a goat-like creature, with cloven hooves and a beard. In Japan it is called Kirin, and in China Ki-lin. The word "unicorn" is based on the Hebrew word re'em ("horn"), in early versions of the Old Testament translated as "monokeros", meaning "one horn", which became "unicorn" in English. The creature is possibly based on the rhinoceros or the narwhal, a marine creature with one horn. In the west it was first mentioned by the Greek historian Ctesias in 398 BCE. According to him they lived in India and he described them as 'wild asses which are as big as a horse, even bigger. Their bodies are white, their heads dark red...
