Details: This poster is of Unicorn of Monoceros, by Christian Riese Lassen. It shows a white unicorn prancing on the beach. In the sky is a large, full moon.
The unicorn is a mythical beast with a single - usually spiral - horn growing out of its forehead. The unicorn's blood and horn supposedly have mystical healing properties. Though the modern popular image of the unicorn is sometimes that of a horse differing only in the horn, the traditional unicorn has a billy-goat beard, a lion's tail, and cloven hooves. Medieval knowledge of unicorns stemmed from biblical and ancient sources.
