Second Barfle Valhaeg, -1100 before the year One=Zero, Nil.
Description: Two leaves of bronze 1mm (0.039in) thick, as 2 hulls reversed keelboat, riveted, & welded together; height 22cm; weight 520g (18.36oz). The side holes are more often used for fastening two cheek protections, a chinstrap, and probably also the bonnet, or inner lining for head comfort. Some helmets add a set with lateral brackets, for hanging ensigns. Nothing prevents to hang a kit for small sculpture, or a nasal protection on the front rivets, & a ponytail, or a neck protection on the rear ones; otherwise why they have made so long conical rivets as a plug with three branches? ...
I find this bronze hat, ingenious, weighed, measured, elegantly thought to be functional, & remarkable.
