Roman battlefield found deep inside Germany

[Epictetus]

Matthew Amt wrote:
The Germans seem to have been very unconcerned about collecting weapons for re-use or recycling. After Teutoberg Forest, they gathered up all the Roman gear and left it in piles in their sacred groves.

The key word here is "sacred" -- it wasn't that the Germans were "unconcerned", but that they were indeed "re-using" weaponry as dedications to their gods.

It sounds like what the Gauls did as well.

...the Aruveni show you a small sword hanging up in a temple, which they say was taken from Caesar. Caesar saw this afterwards himself, and smiled, and when his friends advised it should be taken down, would not permit it, because he looked upon it as consecrated.
