Army composition of the 3rd century crisis?

[Crispvs]

"the next piece that turns up in the record is the Duerne cavalry helmet of c.319, which is a 'ridge' type."

For a slight update on that, there may be a single Intercissa type helmet depicted on the Arch of Constantine, being worn by one of the soldiers defending the city of Verona in this scene.

Although it is not so obvious in this photo, I certainly got the impression it was an Intercissa when I saw the arch when I was in Rome.


"A tombstone from Gamzigrad (copied in Southern & Dixon's Late Roman Army p.93) clearly shows a soldier in an 'Intercisa' type ridge helmet. It probably dates to the early fourth century Tetrarchic period."

Perhaps also of interest is the fact that the other man depicted on the Gamzigrad tombstone, in addition to being mounted, wears a 'pillbox' hat and carries an axe. Similar hats are shown in the early sections of the Constaninian sculpture on the Arch of Constantine.

Thinking again though of the mid to late third century, I recall this thread being a rather stimulating discussion which could be relevant:
