Greek Bronze Helmet of Illyrian Type

Of hammered sheet, with a flaring neck-guard, two parallel double ridges running across the crown front to back, a perforation between the ridges at the front, one on each ridge at the crown, and two at the back, all for attachment of a crest, a raised horizontal ridge above the brow, the perimeter with evenly-spaced gilt-bronze rivets, the proper left cheek-guard with a perforation at the forward tip.
