Searching for pictures of early Gladiator helmets

[Medusa Gladiatrix]

Hi Svenja, thanks for the hint, but if you refer to the helmet pictured here:
http://books.google.de/books?id=5pzs975hnpoC&pg=PA36 which is also in the Junkelmann publication, it does not have a secure providence and might as well be a Roman military helmet of Boetian type.

Yes, that is the helmet which I was talking about. I just wonder if there was in the Republican era a difference between gladiator helmets and military helmets at all since at that time gladiatorial helmets have not had the visor yet but also only cheek guards like military helmets.
