This post comes almost two years too late, but this falsehood has shown a remarkable tenacity:

Background: the “Unite the Right” rally, held in Charlottesville, Virginia on August 12, 2017 really unnerved a lot of people. The idea is that Donald Trump’s election emboldened members of the far (or “alt-“) right to “come out,” and to start demonstrating in favor of racism, nativism, and xenophobia – and to kill a counter-protester by running her down with a car. Donald Trump then claimed “moral equivalence” between the two sides, thereby illustrating his fundamental awfulness. Some of the participants in the rally made reference to things medieval, on the principle that the Middle Ages represent white Europe unsullied by mass non-white immigration. Such references seemingly implicated the discipline of Medieval Studies, and they provoked a huge reaction: the Medieval Academy, along with almost thirty other groups, unequivocally condemned “the appropriation of any item or idea or material in the service of white supremacy,” and continued:
As scholars of the medieval world we are disturbed by the use of a nostalgic but inaccurate myth of the Middle Ages by racist movements in the United States. By using imagined medieval symbols, or names drawn from medieval terminology, they create a fantasy of a pure, white Europe that bears no relationship to reality. This fantasy not only hurts people in the present, it also distorts the past. Medieval Europe was diverse religiously, culturally, and ethnically, and medieval Europe was not the entire medieval world. Scholars disagree about the motivations of the Crusades—or, indeed, whether the idea of “crusade” is a medieval one or came later—but it is clear that racial purity was not primary among them.
This impulse has animated some people ever since. They are not willing to ignore such things as being beyond their concern or control (people refer to the Middle Ages all the time for various reasons, and there’s nothing professional medievalists can do about it, because they don’t actually “own” that time period) or as just a small part of the overall imagery presented at the rally (Charlotte Allen counted “exactly two” medieval costumes, and as Tom MacMaster notes, the protestors made far more use of nineteenth and twentieth century imagery than they did medieval). Instead, it has become extremely important for some people to present the Middle Ages in such a way that “rescues” them from white nationalists. Now, I’m no white nationalist, but as I said before, I don’t care for truth-bending either, no matter how noble the cause.* It’s a bit of a stretch, for instance, to designate the Vikings as “multicultural and multiracial.” (No, you can’t cherry-pick the one former Arab slave who took a Danish wife and settled in Normandy. You need a proper population sample! Numbers are of the essence here. That Vikings ended up losing their identity wherever they settled is the opposite of multicultural.) And as Andrew Holt said about the Crusades:
I can understand Professor Gabriele not wanting to give ammunition to those on the political right with whom he disagrees, particularly when they make crass calls for medieval solutions to modern problems, but misrepresenting what scholars of the crusades think is not the way to do it, and will backfire in the end.
This brings us to the black eagle of St. Maurice, referenced in the tweet above. The story goes that St. Maurice was a third-century commander of the Theban Legion, a Roman unit recruited in Upper Egypt and composed entirely of Christians. Emperor Maximian ordered them to march into Gaul, where they were to be employed in putting down a rebellion. Ordered to sacrifice to pagan gods for the success of the mission, the Thebans refused, and were twice decimated as a punishment – with the survivors then massacred. This took place at Agaunum, now Saint-Maurice, in Switzerland. As the name change reveals, St. Maurice became the stand-in for all the other martyred Thebans, some 6600 of them, and a monastery was established there in his honor. St. Maurice subsequently became a popular medieval saint, a patron of Savoy, Lombardy, Burgundy, and Sardinia, a patron of soldiers (particularly the Pontifical Swiss Guard), and of weavers and dyers, and the namesake of many religious foundations, including twenty-two English churches. Most important, for our purposes, is his patronage of the Holy Roman Empire, which seems to date from the reign of Henry the Fowler (919-936). Henry granted the Swiss canton of Aargau to the Abbey of St. Maurice in return for Maurice’s lance, sword, and spurs, which became part of the regalia used at Imperial coronations. Henry also built Magdeburg Cathedral, dedicated to St. Maurice. Emperor Otto the Great translated the saint’s relics there in 961, and had himself entombed there upon his own death in 973.
Of course, it must be said that, in common with many early martyrs, there is no historical evidence that St. Maurice or the Theban Legion ever existed. The earliest sources attesting to them date from 150 years after their alleged executions, although it is entirely possible that some Christians really were put to death in the area, from which an elaborate story was later spun. According to an article in Greenwich Time, St. Maurice wasn’t depicted as black until the thirteenth century. Why this particular attribute? It’s logical that someone whose origins were so far up the Nile should acquire a sub-Saharan phenotype, and I wouldn’t be surprised if the etymological similarity of “Maurice” to “Moor” had something to do with it. Why this shift should have happened in the thirteenth century I do not know, although it does point to medieval European knowledge of non-white Christians, perhaps inspired by contact with Ethiopians during the Crusades (Ethiopians maintained a presence in the Church of the Holy Sepulcher), or as the result of an Ethiopian embassy to the pope in the late fourteenth century. Just as the Three Kings, from the twelfth century, could be depicted as European, African, and Asian, one for each of the three known continents, so also does a black St. Maurice point to the universality of Christianity. In this sense, the medievalists are right: medieval Europeans clearly were not “racist,” but only because they were deeply Christian, and truly believed that every person on Earth was a potential member of the faith. (An artistically black St. Maurice says nothing about the presence of phenotypically sub-Saharan Africans in Europe.)

Lucas Cranach the Elder & Workshop, Saint Maurice, ca. 1522-25.
But the tweet above was about another emblem: a black eagle borne by one young man on a shield at Charlottesville, and by St. Maurice on a banner in a painting dating to the sixteenth century, judging by the style of the armor. Why does St. Maurice carry such a banner? The image tweeted seems to be a preliminary sketch or an elaboration of a painting of St. Maurice by Lucas Cranach the Elder (1472-1553). It originally formed part of an altarpiece, commissioned by Cardinal Albrecht of Brandenburg, for a church in the Saxon city of Halle. Saxony, of course, was within the Holy Roman Empire, and the banner that St. Maurice holds is actually the banner of the arms of the Holy Roman Empire – a black eagle displayed on a gold field.

“Shield and Coat of Arms of the Holy Roman Emperor, drawn in the style the late medieval period. Also used as shield of arms (generic) by the King of the Romans.” Wikipedia.
One finds other Imperial representations of St. Maurice bearing this shield.

Apparently from the Church of St. Antony, Bitterfield-Wolfen, c. 1499.

Design for Reliquary bust of St. Maurice. Heiltumsbuch, fol. 228v., 1525-1527. Aschaffenburg Hofbibliothek.
In other words, the eagle is associated with the Holy Roman Empire, and St. Maurice is one of the patrons of the Empire; thus does he bear the shield of the Empire. It’s not actually “his,” or it’s only his at second hand. We see this with other saints – sometimes St. George, a patron of England, is shown bearing the three lions of the kings of England, and sometimes St. Michael, a patron of France, is shown bearing the fleur de lys of the kings of France. It might be somewhat egotistical for a votary to assign his own attribute to his patron saint (rather than for a votary to bear his patron saint’s attribute as an act of devotion), but it did happen from time to time.
St. Maurice, therefore, is by no means the “original” bearer of this standard. The reason eagles are associated with the Holy Roman Empire is because the Romans themselves employed eagles as identifying devices, particularly of their legions, and when heraldry developed in the twelfth century it was only natural that the Holy Roman Emperors should have chosen an eagle as an identifying device. Eagles were also used by other successor empires to ancient Rome, including the Byzantines (specifically, the Palaiologos dynasty that ruled it from the eleventh century), the Tsars of Russia, and Napoleon as the Emperor of the French. You could say that Maurice, as the commander of a legion, has a natural right to an eagle as his own attribute, but it would make far more sense for this to be in the form of a Roman aquila (a three dimensional sculpture of an eagle atop a pole), and you would need to find actual artistic evidence of him doing so prior to the twelfth century and the elaboration of heraldry. In other words, the succession seems to be Eagle -> Empire -> St. Maurice, not Eagle -> St. Maurice –> Empire.
As for the other eagle, that appears to be a commercial product of an outfit called West Wolf Renaissance:

From the website:
VIKING BLACK EAGLE SHIELD WITH FORGED IRON BOSS
This is a beautiful handmade and hand-painted wooden Viking shield featuring a Black Eagle design inspired by Viking and Norse shields of old. This shield features a solid oak body which measures about 30 inches across and is 1/2 inches thick…. Because this shield is made of real wood, please note that the wood-grain background shown in the pictures may vary slightly from the shield you receive (this is simply due to the nature of the wood). The front of the shield has also been applied with several coats of topcoat/varnish to protect it through the centuries. So whether for the wall or the battlefield, this shield is well balanced and ready to serve.
Note that the design is “inspired by” Norse shields – it is not necessarily a reproduction of an actual shield. It looks to me like it was taken from Wikipedia’s rendition of the Raven Banner:

Other shields offered for sale by West Wolf Renaissance feature medieval, classical, Mayan, and even cinematic designs (e.g. the emblem of the Galactic Empire from Star Wars, or the houses from Game of Thrones). The company also offers reproduction/fantasy jewelry, clothing, and weapons. Who buys this stuff I do not know, but presumably there are LARPers or “fandoms” out there who enjoy playing medieval dress-up, without scrupulous attention to historic detail.** It might be possible, therefore, that the company helped itself to the shield of the Holy Roman Empire and reimagined it in a Viking style, but my hunch is that the two shields actually have nothing to do with each other. To show an eagle “displayed” (i.e. spread out) is a logical way to show it, black is a common enough color to show it in, and the background hue is coincidental – the HRE shield is formally gold, whereas the Viking shield is just natural wood. (Actually, if the shield is based on a real Norse model, then it would have priority over the shield of the HRE, since the Vikings were active before the development of true heraldry, and we could accuse the HRE and St. Maurice of bearing a stolen Viking shield! Furthermore, it might not even be an eagle: note that it’s in the style of the Raven Banner, and one of the words in the URL is “raven.” It would certainly make sense for the bird to be a raven, given that it’s an attribute of the Norse god Odin.)
Any symbol can have a variety of referents. As the lion is the king of the beasts, so also is the eagle the king of the birds, and like all emblems has been used at various times and various places, by various people, to reference various things. (Actually, in a Christian context, an eagle is most likely to be associated with St. John the Evangelist.) Even a black eagle “displayed” on a lighter-colored background is not the exclusive property of any one group, and you simply cannot take two superficially similar things and juxtapose them in the service of “proving” anything. This is one reason why Dan Brown’s Da Vinci Code is so ridiculous. No, you actually need to establish a chain of transmission, and you would think that art and cultural historians would understand that.† I mean, St. Maurice can also be shown wearing a red cross – does this mean that the “true, original” bearer of this device is St. Maurice, not St. George, St. Ambrose, or the Diocese of Trier?


Medieval Milanetc.
But what do you expect from Twitter? The place is a sewer, the “crystal meth” of social media, and it seems to encourage people in their worst habits of mind. Not only is there the 140-character limit, which prevents the elaboration of complex ideas, there is also a great premium on winning social status through scoring “sick burns” or at least by acquiring lots of followers. Thus our tweeter’s assertion that “Nazis aren’t happy” about her juxtaposition. Who are these people, and are they really all “Nazis”? Or is this all just an imaginary setup to prove to her claque how brave a fighter she is?
Alas, memes can be powerful things, and this one has firmly lodged itself in the medievalist consciousness. Even the executive director of the Medieval Academy went in for it (from All Things Considered, September 2017):
LISA FAGIN DAVIS: There was one young man who was carrying a shield with a black spread eagle that was clearly co-opted from either the Holy Roman Empire or – there’s actually a saint. And it’s kind of ironic. He’s an African saint who carries that standard. And I suspect the gentleman carrying the shield didn’t realize that.
ULABY: That was St. Maurice, revered during the medieval period. He came from Egypt.
It was relayed on History.com in December 2017:
One man carried a round shield decorated with a black eagle. It was a curious choice, considering the eagle image is strongly associated with a Saint Maurice, a Roman general of African descent who became a saint in the early Middle Ages…
The white supremacist in Charlottesville carrying that image was probably unaware that it’s strongly associated with a black Catholic saint, and this disconnect illustrates a larger trend. Hate groups that adopt medieval iconography as symbols of white supremacy usually have misconceptions about that historical era. One of the most common? That Europe in the Middle Ages was unvaryingly white.
Earlier this year I heard a speaker who repeated the idea that the Viking eagle of Charlottesville was really the eagle of a black saint, and just recently another friend posted this to Facebook, from one of her students’ exams:
Historians have the difficult job of interpreting sources in the context they were intended. With white supremacy, gender equality, and current social classes, it is nearly impossible to see the past through an unbiased scope uninfluenced by these current issues. In Charlottesville many protesters used a medieval symbol as a symbol of racial hatred, when truthfully the symbol was worn by a black saint.
So it looks like this notion will be with us for some time to come…
Once again, I state that I am not in favor of white supremacy – although I confess that, apart from the car crash, I didn’t find the Unite the Right rally to be any more shocking than what Antifa routinely gets up to at its demonstrations. But in general I am in favor of proper historical analysis, developed with as much detail as necessary, and not superficial Twitter-zingers, even in the service of things we dearly want to believe.
In brief:
• The arms of the Holy Roman Empire date from the twelfth century and are a reference to the Roman eagle.
• St. Maurice, as a patron of the HRE, bears the arms of the HRE in some depictions, but it’s not a symbol of St. Maurice as such.
• St. Maurice, as an Egyptian, only began to be portrayed as black starting in the thirteenth century.
• The West Wolf Renaissance shield is either a reproduction of a Viking design, or an imagined one (they did not answer my email enquiry).
• If it is a reproduction, it predates the shield of the HRE, and is probably better seen as Odin’s raven; either way, its connection to the shield of the HRE is almost certainly coincidental.
• Truth exists, and it’s more important than feelings.
• Academics should get off Twitter.
* But… quod est veritas? This is an interminable debate, which might go back to the conflict between realists and nominalists in medieval universities, or to Livy and Pollio, if Robert Graves is to be believed. Postmodern historians are fond of saying that there’s no such thing as truth, only competing narratives, and that all history writing is essentially fiction. No, there is no such thing as an omniscient and unbiased historian – we all come to the table with our perspectives and areas of strength (and weakness). But there is a big difference between people who acknowledge this and still hold up the idea that events actually happened in the past, and we can get at them through studying sources that have come down to us from those events, and people who believe that since truth is so elusive, we might as well not even try, and we can say anything we want about the past, because why not?
I cannot abide this position. Any respect that historians get is utterly dependent on people trusting us to deal honestly with the past. They know we are liberal, but they still think that we know some facts that others don’t. However, when we say whatever we want because it is in accord with our politics, that is a problem.
** I am of two minds about this. In general, just as I favor a search for Truth in historical scholarship, I am also in favor of getting the details right in any sort of historic recreation. But I am also fully aware that such concerns can border on pedantry and wet-blanketness. If the goal is to have fun, then why not go for an overall effect, rather than get bogged down in all the details?
† No, I am not prepared to accept any arguments based on “serendipity” or “synchronicity” or any other such mumbo-jumbo.
