This is the first book in the English language to explore the origin and significance of the mythic Chinese unicorn and its influence on later unicorn myths. It proves, beyond a shadow of a doubt, that the Chinese unicorn was not the qilin, but a one-horned female goat-like beast called the zhi (pronounced jhuhr). It also examines the real animals upon which the myth was based. Its most significant finding, however, is that the unicorn zhi was the ultimate symbol of justice under the law in ancient China. Making judicious use of all available evidence, historical, epigraphical, archaeological, art historical and scientific, this book explains how the myth of the unicorn began in China and then gradually spread to other parts of Asia and Europe.
