Principia Discordia is a Discordian religious text written by Gregory Hill (Malaclypse the Younger) and Kerry Wendell Thornley (Omar Khayyam Ravenhurst). It was originally published under the title "Principia Discordia or How The West Was Lost" in a limited edition of 5 copies in 1965. The name, meaning "The Principles of Strife", deviates from correct Latin which would read Principia Discordiæ.
