H.R.Robinson Helmet Typology

[drsrob]

I did write an exposé on the subject, but did not do anything with it as I moved on to other things.

Basically, my opinion was/is that most of the Imperial Italic and Auxiliary Cavalry hemets of Robinson are infantry hemets of the same family as the Imperial Gallic, continuing this family into the 3rd century.

The main series would run as follows:

• Type I. Imperial Gallic A and B
  
• Type II. Imperial Gallic C and D
  
• Type III. Imperial Gallic E and F
  
• Type IV. Imperial Gallic G, H and J
  
• Type IVx. Type IV with cross braces fitted afterwards
  
• Type V. Imperial Gallic K and Imperial Italic G
  
• Type VI. No known examples, only parts, contemporary to Imperial Italic D
  
• Type VII. No known examples, only parts, contemporary to Imperial Italic H
  
• Type VIII. No known examples, only parts, contemporary to Auxiliary Cavalry H
  
• Type IX. Auxiliary Cavalry D and E
  

Next to the main series, there are sub-series, such as the brass panneled (Imperial Italic D, Guttman mouse helmet and Auxiliary cavalry type H from Heddernheim. Another sub-series would be silver-panneled helmets such as the Imperial Italic E[?], Imperial Italic H from Nijmegen.
