I wanted to ask your opinion about a rather mysterious artifact from Prague Castle. It was found in one of the numerous archaeological digs conducted around the castle. The artifact itself is made of wood, with a stitched leather covering, and is shaped such that it looks like it was intended to be worn upon the head. It has been dubbed the "Podevin helmet" since it is alleged that it was worn by Podevin, the servant of St Wenceslas. Research, however, seems to indicate that it was probably created some time between the 11th to 12th century.
As an artifact, the helmet is very unusual; apparently, there is no other comparable artifact anywhere else in Europe. So, my question is, what do you think it's intended purpose was? Is it actually a helmet? Is it a hat? Or do you think it might have been used for some other purpose?
My initial instinct is that it is probably not a helmet. For one thing, it does not look like it would sit upon one's head very well. You'll note that most helmets from this period are fairly rounded and designed so that they will sit reasonably well on one's head, reducing the chance that they will be dislodged in battle. For another thing, to my knowledge, there is no evidence of helmets of this sort in contemporary artwork, which we would probably expect to see if it is indeed a helmet. (For the record however, my personal knowledge of medieval artwork is generally limited to the more western parts of Europe, so I certainly cannot speak on the issue of contemporary Bohemiam military art).
Though I am inclined to think that the Podevin helmet is actually a hat, this belief is not entirely unproblematic. If it is a hat, why did the maker bother to craft it largely out of wood? And why was it covered with leather, rather than another type of material such as linen?
I'm interested to hear your views and arguments on the subject. I have attached a photo of the Podevin helmet below. (For the record, I believe the wood is a modern reconstruction of what was originally found in the grave).
