Roman helmets: Imperial Gallic/Italic and Ridge - comparisons and sources

[Nathan Ross]

If both answers are 'no', then I'm afraid there can be little substance to this debate!

I have used different sources... the beauty of mathematics... Material science, and you cannot deny this... useless diversions and theories denied...

I'll take that as a 'no', then?

at that point you can consider that that helmets was well known from the Romans, that did not adopted it for long time. this is perfectly consistent in the context of a helmet that had inferior qualities, but not for one that had superior qualities, otherwise the Romans would have adopted it immediately.

The earliest known ridge helmet is the Persian one from the Dura Europos siege mine, dated AD257. The first Roman examples appear about 30-40 years later, which is not terribly long in terms of Roman helmet evolution.

However, once introduced they remained in constant production for well over a century. I get the strong impression that nothing anybody says will cause you to question your assumptions, but once again I'd ask why the Romans kept making these helmets if they were so 'inferior'?
