A unicorn was used in Tennessee Williams' The Glass Menagerie to symbolize that the girl was different to other horses. The horn on this unicorn represented her physical handicap, which prevented her from meeting people. When she finally did meet a man, they danced and knocked over the unicorn, breaking its horn off. It's just like all the other horses now, she said, which symbolizes that she has overcome her shyness and lost her virginity.
