The Imperial Crown of Austria was originally made for Rudolph II (1602) as his “personal crown.” Since the coronation regalia couldn’t leave the then-capital city of Nürnberg, Rudolf wore this one when traveling and on his days off from official duties as Holy Roman Emperor. But lest anyone forget who he was, the crown merges a bishop’s miter (to symbolize Rudolph’s divine authority) and a Roman emperor’s helmet (to symbolize his role as successor to the empire that fell in A.D. 476.)
