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

[Crispianus]

It is a logical impossibility to prove a negative. Goldsworthy made the claim. He needs to produce evidence to support it. Look up the meaning of "unsubstantiated".

Nope, you should tell us more about the "nonsense". If it is nonsense, you should be able to justify why an helmet made by flanked parts has the same quality or even more quality than a monoblock helmet. It is logiacl that from a structural point, a monoblock helmet absorb the shots better than one made by flanked parts, because in the ridged one the pivot will offer the breaking point.
And, this is the reason for which today helmets have the main part made as monoblock.

Here you have some examples:





Obviously, you can go to helmets producers and tell them that is nonsense and they can have better quality doing helmets made by flanked pices. Maybe you will start a revolution in the helmets. Or they will tell you it is a nonsense

Are you seriously comparing Kevlar® Composite Helmets with ancient metal working.....  the material would not suit multi piece construction even if it was available in 300AD...
