As I mentioned in this thread ( >>/25137/) the Holy Crown was one important artifact of not only the medieval but modern Hungary too. It wasn't just considered the origin of sovereignty but a legal person in an abstract way too. No wonder it keeps engaged those who are busy solving it's mysteries. And one mystery is the main one: it's origin.
Traditionally it's tied to our first Christian king, Saint Stephen I. It is considered his crown which he was coronated back in 1000 (or 1001) with. As a source from the early 12th century says, he acquired crown and blessing from pope Sylvester II. It doesn't say however that this was The Crown and it even has the implication that there was no crown at all. Since at that time in many cases crowning meant more of anointing with oil and/or girdling with a sword than putting an actual crown on the head. So maybe our Crown never touched Stephen's locks.
So the grand question is who made the Crown and when. Just as many explanations were given as to the problem of the misaligned cross.
