\"Celtic\" military technology and the Romans

[Ab Aeterno]

Thank you for all the replies!

Indeed, I would agree that the Roman legionary has more in common with Greek hoplites and such in general terms, but I'm looking to focus specifically on technological links between early, 'pre-provincial Celts' (if you'll forgive the term) and Roman legionaries up to the reign of Claudius. In particular I'm looking at the Gallic Helmet used, and am wondering does any one have any particular views arguing/ sources proving that the Celts directly influenced Roman armour and improved the standard legionary's chances of survival?

Thanks,
Michael
