SYMBOL OF PERUN - SYMBOL OF TARANIS (?)
Take a look at the symbol named «Gromoviti znaci»:

Now, look at Taranis' wheel:

Could there be a common Indo-European root for this symbol, dating the time of the spread of Indo-European branches across Europe,
or,
is this a result of influences that took place in a more recent period?
