Here is a mid 14th century crown which was “found in Hungary” (if there are exquisite gold and ruby medieval crowns just lying around there, perhaps I am in the wrong place). The crown was probably made by French jewelers who, then as now, were among the best in the world. The crown consists of eight ornamental lily segments held together by hinges (pinned with twining vine-leaf ornaments).
The internet feels that this is the crown of Elizabeth Kotromanic of Bosnia. Elizabeth was a classic “Game of Thrones” style noblewoman who wedded King Louis I of Hungary and then also became Queen of Poland when Louis’ uncle died. Initially a powerless consort, she surrounded herself with ambitious nobles and worked her way into such a position that, upon her husband’s death, she became the queen regent of Poland, Hungary, and Croatia (and de-facto ruler of southern Italy, Bosnia, Serbia, Wallachia, and Moldavia!). Alas, Elizabeth was good at pitting nobles against each other, but she failed to rule well or carefully and she was captured and strangled by her many enemies.
This crown was seemingly donated in her name to the shrine of St. Simeon shrine in Zadar (so it wasn’t exactly lying in a truck stop bathroom or a forest glade, like I made it sound in the first sentence). Whether this crown was hers or not, it is certainly a winsome and beautiful piece, but, like all crowns, it looks a little cursed to me. Maybe it is better if Saint Simeon hangs on to it.
