Hercuniates were aCeltic tribe that migrated toPannonia inIllyria.[1] By the middle of the first century BC, the Hercuniates were a minor tribe that was located along a narrow band of Celtic settlement close to theDanube, on the western side of the river a little way west of modernBudapest. Their name comes from an ancientproto-Indo-European word for anoak. The tribe is referred to byPliny andPtolemy as acivitas peregrina, a wandering tribe that had travelled to Pannonia from foreign parts. Little else is known of them save that they were issuing their own coins by the second century BC.[2] By AD 40 the tribe was eventually subdued by Rome.
