The Ferdinandeum (our provincial museum) is hosting an exhibit of early sacrificial offerings found in and around the Alps for military purposes (g*).

This is evidently something that people did over millennia — gave up offerings of weaponry and other war accessories for battles won, enemies routed or eliminated. The museum stresses that one not only can learn about the conquerors but also about the conquered by the qualities of their weapons.
The exhibit includes many artifacts recovered from Fliess, depots of bronze helmets, shields, swords and daggers, stone axes, Roman figurines. There are also some items on loan from the National Museum of Slovenia, recovered by this man, whose mission in the last several years has been to save the Ljubljanica River’s tens of thousands of treasure from diving treasure hunters and rich collectors. Moreover, that sword in his hand (or one very much like it) might be in the exhibit.
The time frame spans from early pre-historic stone items through the Celtic ages and into the Roman occupation, as the Romans did this as well.
