Thomson's Great Seal Decoded ...******#******... Simon Cassidy, 4 July 2009, Ca. U.S.A.


fig.1 impression of Thomson's 1782 Great Seal
(reconstructed by Walter Manton, 1892)




Congressional Record, U.S.A., June 1782,
and published in Columbian Magazine 1786:

Heraldic specification of the seal's obverse
(front side):

Arms: 
Paleways of thirteen pieces Argent and Gules:
a Chief, Azure. 
The Escutcheon on the breast of the American
bald Eagle displayed, proper,
holding in his dexter talon an Olive branch,
and in his sinister a bundle of thirteen arrows,
all proper, & in his beak a scroll, 
inscribed with this Motto.
"E pluribus unum".–

For the Crest:
Over the head of the Eagle
which appears above the Escutcheon, 
A Glory, Or, breaking through a cloud, proper,
& surrounding thirteen stars forming a
Constellation, Argent, on an Azure field.–

Explanatory notes (also published in both the above sources):

The Escutcheon is composed of the chief & pale, the two most honorable ordinaries. The Pieces, paly, represent the several states all joined in one solid compact entire, supporting a Chief, which unites the whole & represents Congress. The Motto alludes to this union. The pales in the arms are kept closely united by the chief and the Chief depends upon that union & the strength resulting from it for its support, to denote the Confederacy of the United States of America & the preservation of their union through Congress.

The colours of the pales are those used in the flag of the United States of America; White signifies purity and innocence, Red, hardiness & valor, and Blue, the colour of the Chief signifies vigilance, perseverance & justice. The Olive branch and arrows denote the power of peace & war which is exclusively vested in Congress. The Constellation denotes a new State taking its place and rank among other sovereign powers. The Escutcheon is born on the breast of an American Eagle without any other supporters to denote that the United States of America ought to rely on their own Virtue.

fig.5 Eta Aquilae's position in the Eagle, and regular varying brightness.

Apart from its possible use as "equator star" in the late sixteenth century the other curious property of Eta Aquilae is its variable brightness graphed above.
This property of our star was only officially discovered in late 1784, by Edward Pigott, after two years of observational work on variable magnitude stars with John Goodricke in York England.. This synchrony between the covert appearance of Eta Aquilae, encoded into Thomson's U.S. Seal, and the renewed British interest in variable stars (which led two yeas later, to the discovery of Eta Aquilae's weekly variability) may be more than just coincidence. For there is a character, John Maurice, who straddles all three worlds of (i) international diplomacy (being an ambassador himself from Saxony to Britain and even in touch with Benjamin Franklin in Paris), (ii)  the circle of English astronomers around William Herschel which included Piggot and Goodricke (Maurice being himself an avid and competent mathematical astronomer and a good friend to King George III's personal astronomer) and (iii) the world of late sixteenth century English astronomers by virtue of his discovery of the "Waste mathematical papers" of the Elizabethan/Jacobean astronomer Thomas Harriot, at Petworth (a country mansion of Harriot's patron the Earl of Northumberland) where they had lain undiscovered for more than 150 years before Maurice's status as second husband to the Dowager Countess of Egmont gave him the opportunity to find and study them in privacy, while Petworth was entrusted to his wife (pending the coming of age of the rightful male heir to Northumberland's property).

   According to U.S. government publications, the Continental Congress began the design process of the Seal of the United States in July of 1776. See, for instance the official booklet, downloadable at: state.gov/www/publications/great_seal.pdf
   The official histories describe how multiple congressional committees and their consultants amassed dozens of suggested elements over the ensuing 70 months of the Revolutionary War, without gaining congressional approval for any proposed design made up from selections of these proliferating elements.
 
   Then, after a new committee, and a new heraldic consultant in early May of 1782, failed to come up with anything practical for an obverse (front side of the Seal), the Secretary of Congress took charge, on June 13th., of the whole design. Consequently, the verbal description at left (below fig.1) using just about half a dozen of the amassed collection of elements, was presented to Congress by its Secretary, Charles Thomson, as a design for the obverse side of a two-sided seal. This description was finally approved for execution, by that very session of the Continental Congress on June 20th. 1782.

   While Thomson's upright character and honesty would certainly not allow him to present deceptive or false explanations to congress, his role as the keeper of congressional secret affairs would certainly allow him to omit from the public record any additional intended meanings of the seal's official heraldic specification that he or any fellow congressional conspirators deemed unfitted (and unnecessary) for public edification. A memo (with an enclosure now missing) that he later sent to James Madison proves that Thomson did indeed intend a covert set of alternative meanings**.

   I therefore note that one full half of the heraldic design (i.e. the Crest) gets a mere single sentence of explanation by Thomson; viz. "The Constellation denotes a new State taking its place and rank among other sovereign powers" and the large central Eagle (which had no precedent in the proliferating elements prior to June 1782) is specified as "bald" but explained only as "American" and as  symbolic of a Virtue of America.

   It may thus be instructive to consider how additional unstated meanings, construable to an eagle or a constellation of stars, could represent a Virtue or Silver Lining of the United States of America and/or even facilitate this "new state taking its place and rank among other sovereign powers", in a situation where France and Holland had already recognised the new American nation, but the British Crown, having ceased most hostile action in America on the advice of Rockingham, its new Prime Minister, still refused to acknowledge American independence, even tacitly.

   To do this we first need to consider the immediately forseeable uses of this seal and examine the actual pictorial content of the very first instantiation (as a die) of the congressionally approved design.

   A resulting bronze die of the obverse side (but not the reverse) was indeed soon commissioned and delivered by Thomson (of which the top left illustration, fig.1, is ostensibly a true facsimile of that die's impression, according to the 1892 State Department monograph, "The Seal of the United States"). 
   It was certainly acquired for congress, before September 1782 by their Secretary, Charles Thomson (its official keeper until 1789) and he and the temporary president of congress, Hanson, first used it in that month. 
   Predictably, this first use was to vest General George Washington with the power to treat with the British Generals in America about prisoners of war, in furtherance of an end to all hostilities and thus bring closer a formal and final end to the Revolutionary War. Whereupon, Franklin in Paris, finally got the British (including a representative of King George) to sit down and discuss American Independence, a discussion which would lead, in November, to a formal signing of Provisional Articles of Independence.

   We now note certain liberties taken with the approved heraldic prescription.

   First, the eagle of the die does not appear to be an "American bald Eagle" since it has the eagle's "crest" of most species of eagle (which are thus not bald). This may have been done to emphasize its generic eagleness and/or to establish a verbal link between the Crest of Stars and the "crest" of the eagle, since...
   Second, the eagle's head has been made to protrude through the clouds surrounding the Constellation, and....
   Third, the radiating lines of the "gold" glory are not properly heraldically represented as a series of dots, with the effects that (a) the motto in the eagle's beak can now apply as equally to the Constellation of the heraldic Crest as it does to the Escutcheon of the heraldic Arms and (b) there are unbroken lines of glory directly connecting the silver constellation of the heraldic Crest to the anomalous "crest" of the Virtuous Eagle, perhaps positing some equivalence between the constellated Crest of stars and a crested bird.  
   Fourth, the Constellation itself disobeys the heraldic convention of a random arrangement of stars (obeyed in all extant illustrations of previously proposed uses of a Constellation in the long-desired U.S. seal). Instead, the Constellation of six-pointed stars was itself arranged in the form of a six-pointed star surrounding a single central star. This departure from the rules of heraldry not only emphasizes the applicability to this star-of-stars of the motto, E PLURIBUS UNUM, in its overt meaning (one whiole from many parts)  but also allows the unique central star to be an alternative UNUM in the motto's alternate classical interpretation as "one chosen from among many".
   Fifth, reflecting the seven tail feathers of the Eagle, the clutch of thirteen arrows was (according to Walter Manton, State Department illustrator, 1892) composed of two groups, an upper group of seven large arrow points and a lower group of six smaller arrow points squashed up against the border of acanthus leaves. This emphasis of seven of the thirteen arrows not only suggests that Thomson intended a deliberate reference to the original Arms of the Dutch Republic (wherein a lion rampant clutches seven arrows representing the seven Netherland states rebelling against Spanish rule, almost exactly two centuries prior in 1581),  but it also emphasizes the same differentiation of thirteen objects displayed on the shield (escutcheon) where there are seven silver bars and six red bars (though the bars are interleaved rather than, as the arrows, grouped), and also helps to draw attention to the position of the central UNUM of the thirteen stars as the seventh star, using any conventional reading order (left to right, top to bottom, right to left or bottom to top) of the silver constellation.

  The combined effect of all five of these peculiar liberties is to strongly suggest an alternative symbolism designed to declare the identity of a particular star in a particular heavenly constellation which may somehow help the United States of America to better "its place and rank among other sovereign powers" particularly its standing with Britain, its King, George III and his emissaries and military representatives under the command of his American Generals.
   
   We are now in a position to identity and name this particular star and to investigate whether its covert indication on Thomson's seal could have such political advantage.

   The identification itself, is easy and incontrovertible when we note that there are only three elements of the seal that can share a name with an actual celestial constellation or asterism in the European tradition of Thomson's era. 
  These are the Eagle (Aquila, in the conventional latin used to identify stellar constellations), the Shield (Scutum in latin) and an Arrow (Sagitta in Latin). That these three latin constellations are actual neighbours in the sky suggests that we are on the right track. 
  Moreover it seems certain that of the three, Aquila the Eagle would be the constellation covertly intended by Thomson's seal Crest, since (apart from the Crest-to-eagle's-crest association noted above) the other two (Arrow and Shield) were never composed of as many as 13 bright stars and the Aquila constellation of the British Astronomer Royal Flamsteed, ca. AD1725, actually contained 5 (alpha, beta, delta, epsilon and eta of Scutum) of the 7 chief stars previously claimed in AD1690 for Scutum by its creator, the astronomer Hevelius (see Wagman, M., "Flamsteed's Missing Stars", Journal for the History of Astronomy, Vol.18, P.209, 1987, pp212–213). 
   The Eagle constellation does have about 13 bright stars readily visible to the naked eye (magnitude 4.5 or brighter) and the seventh in order of brightness (and Greek alphabetic designation) was thus known in Thomson's time as Eta Aquilae (or as Eta Antinous by some) or even possibly by the hebrew name בֶזֶק, or Bazak (in English), since hebrew properties may be indicated by Thomson's Star-of-David style of arrangement. Note that Bazak does begin with the letter B (hebrew Beth) which is also the seventh letter of Thomson's Seal's thirteen letter motto "E PLURIBUS UNUM". 

Since this alternate astronomical symbolism covers all elements of the obverse of Thomson's Seal except for the olive branch (towards which the eagle is facing), we might interpret this as Thomson's secret offer of peace from his Congress of the United States to King George III (via his emissaries and Generals in America), sealed by a mutual understanding of some deep significance of the star known as Eta Aquilae, Eta Antinous or, under its possible hebrew name, "Bazak". But why under the identity of this obscure star? Could it have something to do with the fact that this star precessed across the celestial equator almost exactly two centuries earlier? By modern retro-calculation this happened during the years 1579-1581, and Eta Aquilae was thus the bright "equator star" not only at the moment of formation of the Dutch Republic of the Seven United Provinces (which had just recognised Thomson's United States in 1781), but also during the first official attempts by the English monarchy to colonise America (Humphrey Gilberts patent from Queen Elizabeth I) and also immediately prior to the Gregorian reform of the calendar (proclaimed by the Pope in Italy in February 1582) which Papal reform's bicentennial was being celebrated in Italy as Thomson designed his Great US Seal.

A bright "equator star" in those years, between the announcement of intent (in the Papal calendar commission's "Compendium" published in 1577)  and the actual enforcement (Papal Bull of 1582), could indeed have been useful for 16th. century astronomers wishing to check the accuracy of the proposed calendar reform, since the intellectual excuse for disrupting the old Julian calendar was the desire to restore the instant of vernal equinox to the 21st day of March, which instant had regressed back in the old calendar to 10 or 11 March. This regression of the instant of vernal equinox was taken as evidence that the Julian rule (of a leap-year every four years)  had created too many leap-years (about one too many every 133 years). The Compendium's Papal reform proposal consisted of omitting 10 dates (most Catholic countries did this in October 1582 or 1583 by jumping from the end of 4 October straight to 15 October instead of to 5 October) in order to bring the equinox forward to the 20th or 21st of March, and to alter the leap-year rule to omit the leap-day in most centurial years (the Compendium recommended that only every fourth century-year should have an extra date in February, e.g. AD1600, 2000, 2400 were still to be leap-years). The instant of vernal equinox is defined astronomically as the yearly occurrence of the Sun's transit northwards across the celestial equator and thus a bright star, in this case Eta Aquilae, on the celestial equator could have served knowledgeable astronomers to uniformly mutually calibrate (during summer meridian passages of Eta Aquilae), then state-of-the-art, 16th. century camera-obscura solar-observatories, for use in the following March for deducing the hour of the equinox by interpolating to the corect equatorial spot between the two consecutive noon meridian passages occurring before and after the instant of equinox.
That this same interval of several years before the implementation of the Papal calendar reform also coincided with the English monarchy's first attempts to colonise North America (by Queen Elizabeth's 1578 patent directing Sir Humphrey Gilbert and his fleet to do so within six years) suggests Thomson may have believed that these three 200-year old events (calendar reform, Eta Aquilae on the equator and the English monarchy's first overt interest in colonising America) were somehow connected through some hidden Virtue of America and that this Virtue's secrecy was still valued in Thomson's day by the British monarchy in the person of King George III. 


**  footnote added by S. Cassidy, July 4, 2010:

Question:  
Why bother looking for hidden meanings
in the US great seal when
there is a perfectly
good public interpretation of all its elements?


Answer:  
The memo below constitutes sufficient
evidence that the Seal conveyed an alternate

covert meaning, since the memo was written
by the seal's designer, Charles
Thomson
(1 Dec.1804 to Sec. State, James Madison).

The fact that the "enclosed" "explanation" is 
lost cries out for an honest and historically
informed attempt to reconstruct and explain
Charles Thomson's lost covert "Sentiments".

******#******to Madison 1804******#******
Enclosed I send you an explanation
of the Device for an armorial Atchievement
and Reverse of a Great Seal
  for the United States
in Congress assembled

It was drawn up when I made report &
contains the Sentiments
which I had in mind
when I was considering the subject, and
which
I wished to express covertly by the device.

It has never been published
nor have I ever given a copy of it.

If you think it worth preserving
you may lodge it in your office,

if not, destroy it.
