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.
It is rather the nation's stamp of authority, sovereignty and power, gracing our cash and embossing the most important of documents from its home at the State Department, which has held it since the days of Thomas Jefferson, the first secretary of state.
Not that the Seal's symbols - the all-seeing eye, the unfinished pyramid, the Latin phrases, the bald eagle clutching an olive branch and arrows and the number 13 - aren't powerful.
They are, historians say. Yet their meanings have been misidentified, misunderstood and misrepresented almost since the Continental Congress first commissioned the Seal in 1776.
It would be another six years before the original design was approved and another 128 before it evolved into its current form. Along the way, a movement to decipher the Seal's meaning with ancient Egyptian, mystical and otherwise otherworldly explanations has gained currency.
The Internet age has seen an explosion in such conspiracy theories, many which have now been ingrained in public consciousness through the popular "National Treasure" movie franchise that serves up a combination of Masonic lore and historical myths in blockbuster Hollywood fashion.
All rubbish, according to historians, who say the Seal's symbolism is far less ominous or revelatory than many believe.
Secretary of State Condoleezza Rice, the Seal's 66th and current custodian, on Tuesday inaugurated a new exhibition to commemorate its 225th birthday and trace the history and evolution of the symbolism.
"This exhibit honoring the Great Seal affirms our continued belief in the values of our founding," she said. "The Great Seal symbolizes the unity, strength and independence of a new nation, the United States of America."
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.
Among the highlights:
"People are just not aware of the complexity and intent of the symbolism and what our Founding Fathers were trying to do with it," said Priscilla Linn, senior curator at the U.S. Diplomacy Center. "The hidden treasure in the Seal is the courage and presence of mind of the people who created it and created these values for the whole country."
