I didnt found not even ONE link about Scythian civilization before 700BC. For example
Scythian World claims that the tribes lived 6 to 3 centuries BC.
Also it is the first time I hear about a nomadic tribe with good metallurgy. So
bronze swords in 600 BC maybe where good for Scythians but they were not good enough for Persians and Greeks.
Dorians came to Greece 1100 BC and overruned Achaioi because they had
iron swords. Agamemnon times are over. Troia is fallen...
