In the comments to my last post, Limpey speaks positively of the helmets worn by the Teutonic Knights and I can't say I blame him. Those helmets are pretty awesome, even if, as I understand it, they're actually the medieval equivalent of "parade dress" and no knight would ever have gone into battle wearing one (though I'm sure someone will speak up if I'm mistaken in this impression). Still, the helms go a long way toward establishing the German crusaders as sinister villains, so I'm willing to forgive the historical inaccuracy. In fact, in watching Alexander Nevsky, I noticed there is a lot of cool headgear associated with the German characters.
Take, for example, these helmets, worn by the footsoldiers of the crusading army. Again, I don't believe they're historically accurate for the 13th century, but they are appropriately sinister. That they look a lot like the German Stahlhelm is, of course, entirely the point.
And here's Hermann von Balk, Grand Master of the Teutonic Knights, in his terrific horned helmet, surmounted by a crown to denote his status as a lord. The real Von Balk did not participate in the Battle of the Ice, having been dead for several years beforehand, but he is remembered for his military conquests and his ruthlessness toward pagans in the Baltic lands who resisted Christianization.
Here are three lords among the Teutonic Knights, each of whom has a distinctive ornamented helmet. The two on the left, Hubertus and Dietlieb, are granted fiefs in the conquered Russian lands by the Grand Master.
My favorite in the above picture is the unnamed guy on the right, who can also be seen below:
The Knights aren't the only ones who get nifty hats. The unnamed high-ranking cleric among the crusaders wears some noteworthy headgear. The first is this broad-brimmed galero, which would suggest that he's a cardinal, even though the galero didn't enter common use until after the Battle of the Ice took place. Again, I won't fault Eisenstein for his decision, because the galero is a great hat.
And, of course, no discussion of the hats of Alexander Nevsky would be complete without the aforementioned cleric's miter, which rather unsubtly includes swastika-like symbols in place of crosses.
