The famous Niedermörmter Roman helmet of the 3rd century BC. Back view. This style of helmet with hinged cheek pieces and a large neck protection was found in the river Rhine (now in the Mainz museum). It is a Weisenau type. Along with the elaborate applique and perforated brow, this helmet sports a unique design element on the crown: what are described as either "Mice and cheese" or "Mice and bread".
This helmet is one of the best preserved of its kind face helmets as synthesis were not in combat, but worn by Roman cavalry soldiers in parades and competitions. The tournaments and parades appear under the Emperor Hadrian 117 -138 A.D.
