The Great Seal of the United States
Over a span of six years (1776-1782), the combined efforts of fourteen revolutionaries, including Thomas Jefferson, John Adams, and Benjamin Franklin, created the Great Seal of the United States, a seal that encapsulates the Founding Fathers’ beliefs and values.
Though the obverse of the Great Seal includes no Masonic symbols, Dan Brown makes much of its use of the number 13 and that, when Robert Langdon and Katherine Solomon superimposes Solomon’s seal over the reverse’s Great Pyramid with its Masonic all-seeing eye, the touch points spell the word “Mason.”
