There are great many pitfalls and impossible questions in the "crown-research" as some call it, and I'm not surprised great many theories were given birth. Maybe I'll pull out a few, the more interesting or the ridiculous ones, or some claims about the crown (seen some reconstructions of the hypothetized "corona latina", they are really fun, maybe I can find them).
The history of the Holy Crown was investigated by many people - professionals and amateurs alike - both with great care and great fantasy. I wonder if other, foreign piece of artifacts was researched with such thoroughness? For example the Iron Crown of Lombardy as we now it today was really made and used by whom we think it was? I've never actually looked into it.
