Conspiracy theorists take note: The myths surrounding one of America's oldest and most enduring national symbols are about to be debunked ... if you believe the government, that is.

The keepers of the Great Seal of the United States, the familiar emblem on the back of the $1 bill, want you to know what it is not. It is not a sign that Freemasons run the country, it has nothing to do with the occult, and it does not contain clues to a fabulous hidden treasure....

On Tuesday, Secretary of State Condoleezza Rice, the Seal's current custodian, will inaugurate a new exhibition to commemorate its 225th birthday and trace the history and evolution of the symbolism.

The Seal will remain at the State Department but the interactive exhibit is designed to travel and curators hope it will dispel the rumors and educate Americans about the real meaning of the symbols.
