byzantio:

The Hungarian crown; possibly made in a byzantine workshop in Constantinople in the early 10th century and sent as a gift to the ruling dynasty in Hungary. Byzantium always tried to impress and increase its influence by sending luxurious objects.

The crown itself is full of enamels depicting the Christ, byzantine emperors with halos and a Hungarian king with no halo. It is worth saying that in this case the Magyar ruler accepted his place in the byzantine hierarchy; on the contrary in the Pala D’Oro enamel depiction of the Doge, his shoes have been repainted with the imperial colour and the original blue has been replaced. The Doge couldn’t accept he is below any emperor.
