A New Helmet

[Nathan Ross]

What about the dating on this helmet?

That, I think, is the Vindonissa helmet, found in 1979, no Robinson classification but close enough to the Sisak and Besancon helmets (the latter mentioned by Crispus above) to share the 'Gallic F' bracket, and the same sort of mid-1st-C dating.

Incidentally, does anyone have a theory about why so many extant Roman (infantry) helmets seem to date from the middle years of the 1st Century AD? There seem to be scores of them, compared to, for example, only one from the entire first three quarters of the second century (and even that one - the Hebron helmet - is a bit of a guess...)
