An amazing example of part of the cross braced reinforcement of a later Roman (commonly typed as a Neiderbieber class) helmet.  This example is very well preserved with a smooth green patina.  Two knob like rivets with flattened sides accentuate the attachment areas of the reinforcement bar.  This item appears to have most likely been folded in ancient times near the slotted area (as seen by the patina damage caused by contemporary restoration).  This was perhaps done as part the stripping down of a used helmet for scrap or parts to fit on another helmet.  The gap in the rivet area clearly indicates that the helmet itself was also made of bronze and was probably close 1-1.5mm thick.

As one can tell from the example photo's below (as well as the item pictures) this cross brace would have interlocked with a similar piece that extended from the peak of the helmet down the back.  This in-genius way of attaching the cross brace allowed for strength and stability and made them easier to attach or replace.

The design clearly shows how this helmet was the most advanced helmet, perhaps ever made across the whole historical spectrum.  The cross reinforced bowl was superior in strength and would dissipate the force of a blow.  The pointed peak attachment with it's angles served a similar purpose, protecting from both a downward stash and a forward one, deflecting the blade off to the side.  The cheek pieces also were more enclosed covering more of the face and ear area.  The flared ends of the cheek pieces also served to protect and deflect the force of an enemy.  The neck guard continued to be enlarged and provided a superior level of protection for the neck and shoulder area.

This artifact was once part of a great Roman helmet that served to bring the empire through a difficult 3rd Century into the renewed prosperity of the 4th Century.
