H.R.Robinson Helmet Typology

[marcos]

If I clean my mind , forgetting everything knew until now about roman infantry helmets, and thus not having baised opinions , I can see 2 leading groups of helmets.

First: from the beginning to the late republic - first empire.
Basically chaste , bronze, often with the knob on the top (but not always) , with a not elaborate neck guard.
According Robinson , from montefortino to coolus.
The picture below , one among several, if just to explain the type of helmet.



Second: from the first the empire to III century (more or less).
helmets more complex , made from iron, with a neck guard wide and normally down going, without knob on the top. Normally having eyebrows.
More elaborate than first group , and essentially different.
imperial gallic-italic according Robinson.

Of course , into these two groups we can have some under-groups, but my sensation is these are the two main .
