The Publius Enigma is an Internet phenomenon and an unsolved problem that began with cryptic messages posted by a user identifying only as "Publius" to the unmoderated Usenet newsgroup alt.music.pink-floyd through the Penet remailer, a now defunct anonymous information exchange service.

Although all great music is subject to multiple interpretations, in this case there is a central purpose and a designed solution. For the ingenious person (or group of persons) who recognizes this - and where this information points to - a unique prize has been secreted. How and Where?
