This is the most complete example of a small but distinctive group of helmets that are characterized by the presence of raised central ridges, applied brass borders, and the use of brass rivets rather than leather laces to join the major components. The finial at the top of the helmet is decorated in gold and silver with a protective mantra reading OM AH HUM. The brim has a series of five motifs known as dry skulls (thod skam), linked by tendrils of flames.
