On the One Dollar Bill is the above Great Seal the words "Annuit Coeptis" which translates as "the beginning of" and below the pyramid is "Novus Ordo Seclorum" which is Latin for "New World Order," or "A New Order of the Ages." On the front of the base of the pyramid are the Roman numerals MDCCLXXVI which is of course 1776 the year that the United States had its Independence. I have read in other books that when Thomas Jefferson was trying to write the early formats of the Declaration of Independence that a knock came to his door. Upon opening the door someone handed him a piece of paper with the above Great Seal on it. Supposedly this was its origin, uncertain is whether Masonic groups or the supposed Illuminati was the instigator. Others say that the early founding fathers were Freemasons, outer circle members of an arcane world "brotherhood." Benjamin Franklin initiated the symbol of the Great Pyramid onto the Great Seal of the United States.
The pyramid in the Great Seal represents the unfinished Tower of Babel. Thus we have a comparison to ancient Babylon, but the real question is whether this is the prophetic Babylon? And as stated on the previous page there is definitely influence from ancient Egypt by the significance of the eye of Horus.
Some sources claim that the twelve or thirteen layers of the pyramid have some significance to time periods progressing from 1776 A.D. Whether this is valid I can not say.
