As an aside, the Scythians were not in what we'd today consider Persia (Iran). They originated around the north coast of the Black Sea, and extended east and southeast from there along the Eurasian steppe.
It truly is fascinating to follow the flow of cultures through time - sometimes coexisting, sometimes crashing against one another, yet other times melting together.
