Montefortino helmet

 The Montefortino helmet was a type of Celtic, and later Roman, military helmet used from around 300 BC through the 1st century AD with continuing modifications. This helmet type is named after the region of Montefortino (frazione of Arcevia) in Italy, where a Montefortino helmet was first uncovered in a Celtic burial (photo).

A line of warriors bearing spears and shields march to the left, bringing up the rear is a warrior with no shield, bearing a sword, and wearing a boar-crested helmet which resembles helmets from later Germanic cultures. Behind him are three carnyx players. In front of this group a dog leaps up, perhaps holding them back. Behind the dog, at the left side of the scene, a figure over twice the size of the others holds a man upside down, apparently with ease, and apparently is about to immerse him in a barrel or cauldron.
