The Cimmerians who preceded the Scythians used Iranian proper names, and probably represented this Iranian element in greater purity.
The Scyths having fallen upon them from the north-east, the Cimmerians appear to have given way in two directions, towards the southwest, where the tombs of their kings were shown on the Tyras (Dniester) and one body joined with the Treres of Thrace in invading Asia Minor by the Hellespont; and towards the south-east where another body threatened the Assyrians, who called them Gimirrai (Hebrew Gomer; Gen.
Ashkenaz) whom the Assyrians welcomed as allies and used against the Cimmerians, against the Medes and even against Egypt.
They have been referred to the Cimmerians, but for this there is no clear evidence.
In the 7th century B.C. these Cimmerians were attacked and partly driven out by a horde of newcomers from upper Asia called Scythae; these imposed their name and their yoke upon all that were left in the Euxine steppes, but probably their coming did not really change the basis of the population, which remained Iranian.
