Thraco-Dacian expansion during Late Bronze Age and early Iron Age

[diegis]

Jorandes himself claims that Vesosis waged a war with Scythians, is beyond one's understanding where you saw Getae

Jordanes V.44
"Then, as the story goes, Vesosis waged a war disastrous to himself against the Scythians, whom ancient tradition asserts to have been the husbands of the Amazons.(Tunc, ut fertur, Vesosis Scythis lacrimabile sibi potius intulit bellum, eis videlicet)
Thus we can clearly prove that Vesosis then fought with the Goths, since we know surely that he waged war with the husbands of the Amazons."

Let me give you a better example, Valerius Flaccus (Argonautica), few centuries before Jordanes (who, as many times, messed up few things there)

<<Delighted with the temple’s varied imagery the leader likewise casts his gaze upon eh double doors, beholding here the infancy and origin of the Colchian race; how first their king Sesostris22 waged war upon the Getae, how terrified by the slaughter of his people he withdrew some to Thebae and his native stream, and settled others upon the land of Phasis and bade them be called Colchians>>
