The inventiveness of the Celts

[varistus]

Also more is being discovered all the time about the Celts. Apparently they had advanced metal making skills, greater than the Romans who copied some things, like chain mail. I also have a theory about the gladius and the Celtic swords. I feel the Romans just didn`t have (or copy) Celtic skills for making a longer sword. Romans perhaps only could smelt a sword that was short and fatter because of this. A superior blade can be longer and narrower which requires advanced smelting. Either the Romans never copied whatever reason, stubbornness for sentimental reasons to stick with the gladius perhaps or the Celts were able to keep their secrets.
