An old tradition holds that the location of the discoloration in the marble of the Washington Monument prefigures the end of the Republic:
The discoloration represents the division between the two phases of the Monument’s construction. The phases used marble from different quarries, resulting in a clear visual boundary. The pause between the phases lasted nearly two decades, from 1858 to 1876, and although the original reasons for it are complicated, it was drastically lengthened and nearly made permanent by the Civil War. We may take the discoloration as representing the Civil War, forever the spiritual halfway point in the United States’ history.
The discoloration occurs at 46 meters up, and the Monument’s total height is 169.29 meters; thus the dividing line is 27.17% of the way up. Depending on whether you use the beginning of the Civil War (1861) or its end (1865), the corresponding end year for the United States is either 2089 or 2104 — that is, the year 1861 (or 1865) occurs 27.17% of the way from 1776 to 2089 (or 2104).
So it looks like we’ll make it to sometime between 2089 and 2104. We had a pretty good run. Maybe someone else will find a use for our Constitution, especially since it’ll be in such good condition. (“Like new! The previous owners barely took it out — it just sat in the garage for the last few years, really.”)
The construction of the Monument is itself is a fascinating story. It turns out that our national weakness of historical amnesia is sometimes a blessing. Then too, it could be said that every nation’s weakness, and blessing, is historical amnesia.
Though if start date is beginning of “constitutional” government (1789), the U.S. has until 2054 or 2069.
However, for maximum profit we should have the possible end come as soon as next year, therefore the beginning is 1804.
The Republic truly began with the acquittal of Samuel Chase and aid to and subsequent embargo of Haiti, setting long-term patterns that characterize the U.S. to this day. Which could be nearly the last day, so buy my paraphernalia, book my lectures, etc!
