Pannonian Celts, "Puppet rider" tetradrachm, early 3rd c. BC. 

Laureate head of Zeus right, his eye represented by an arrowhead.
Celtic inscription above puppet-like horseman right, 
left arm raised, triskeles beneath the horse, Pi under
horse's front hooves. 

Note: The triskele variants date from the mid 3rd c. BC 
onwards, whilst the rarer issue with the monogram of 
the Paeonian king Audoleon, are from a slightly earlier period.
