Sasanian crowns

The Sasanian crowns (Persian: تاج‌های ساسانی) refers to the crowns used by the monarchs of the Sasanian dynasty of Iran.

Many of the later Sasanian crowns were suspended by a chain of gold from the top of an arch in the audience-hall as the ruler's neck could not support the weight of the elaborate crown.

[1] The later sources cite that the practice of "hanging crown" was extended to any setting in which the monarch appeared, including their deathbed.

A crown was also suspended during the birth of a royal heir.

The Byzantines adopted this custom from the Iranian court.
