They were brutal and aggressive, and their main concern in life was war. Herodotus and Strabo place them on the banks of the Thermodon ,   while Diodorus giving the account of Dionysius of Mitylene, who, on his part, drew on Thymoetas, states that before the Amazons of the Thermodon there were, much earlier in time, the Amazons of Libya. Notable queens of the Amazons are Penthesilea , who participated in the Trojan War , and her sister Hippolyta , whose magical girdle, given to her by her father Ares , was the object of one of the labours of Heracles. Diodorus mentions that the Amazons traveled from Libya under Queen Myrina. The Scythian women may have inspired the myth.
