This is a Roman battle helmet, probably for a cavalryman, found in a gravel pit in Witcham, England. It is thought to be from AD 14.  

A masterful piece of work, and one can only imagine the circumstances that caused it's owner to toss it aside.  Imagine a lone Roman on a horse, the sole survivor of his troop, madly riding south to escape a horde of Celtic wild men hot on his heels, desperately throwing off everything heavy.  As the chase continued over the hill, the helmet came to rest in a low marshy spot, surrounded by tall grass and invisible to anyone not standing right next to it.   Only centuries later was it rediscovered by modern people as they dug gravel from the pit, it's existence only suggesting the drama that must have unfolded so many years before.
