Eastern Celtic Tribes "Mystery Artifact", c. 2nd-1st Cent BC
Copper alloy; 140mm (diagonally)/98gm (!)
Con/ plow-broken, green patina with decorations.
Ground-found in Croatia, this odd artifact is certainly from pre-Roman incursion into the Balkans. We have no clue as to its use, other than that is heavy and decorated.
Perhaps you do? :-)
