What is the truth of the unicorn, sometimes described as fierce, sometimes as gentle, sometimes only to be subdued by a virgin? In art and literature, it has been a part of the cultures of ancient China, Egypt, Greece and Rome, as well as Jewish and Christian religions. Included in this paper is James Thurber's "A Unicorn in the Garden", Anne Morrow Lindbergh's poem "The Unicorn in Captivity," and descriptions of the unicorn tapestries at the Cluny Museum in Paris and the Cloisters in New York City.
