Despite the fact that it has never been seen, almost everyone is familiar with the legendary unicorn (独角兽)．Descriptions of unicorns have been found dating from ancient times. The great philosopher Aristotle theorized that there were two types of unicorn—the socalled Indian Ass and the Oryx，a kind of antelope. Unicorns are often used in the logo of a noble family, town council or university as their special sign. Even Scotland is represented by a unicorn.
