In Greek mythology, the Amazons were a tribe of warrior women related to the Scythians and Sarmatians, both of whom are considered Iranian peoples. Apollonius Rhodius, in his Argonautica, mentions that the Amazons were the daughters of Ares and Harmonia (a nymph of the Akmonian Wood), that they were brutal and aggressive, and their main concern in life was war. Lysias, Isocrates, Philostratus the Elder also say that their father was Ares.
Herodotus and Strabo place them on the banks of the Thermodon River. According to Diodorus, giving the account of Dionysius of Mitylene (who in turn drew on Thymoetas), the Amazons inhabited Ancient Libya long before they settled along the Thermodon. Migrating from Libya, these Amazons passed through Egypt and Syria, and stopped at the Caïcus in Aeolis, near which they founded several cities. Later, Diodorus maintains, they established Mytilene a little way beyond the Caïcus. Aeschylus, in Prometheus Bound, places the original home of the Amazons in the country about Lake Maeotis, and from which they moved to Themiscyra on the Thermodon. Homer tells that the Amazons were sought and found somewhere near Lycia.
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. Amazon warriors were often depicted in battle with Greek warriors in amazonomachies in classical art.
Archaeological discoveries of burial sites with female warriors on the Eurasian Steppes suggest that the Scythian women may have inspired the Amazon myth. From the early modern period, their name has become a term for female warriors in general. Amazons were said to have founded the cities and temples of Smyrna, Sinope, Cyme, Gryne, Ephesus, Pitania, Magnesia, Clete, Pygela, Latoreria and Amastris; according to legend, the Amazons also invented the cavalry.
Palaephatus, who was trying to rationalize the Greek myths in his On Unbelievable Tales, wrote that the Amazons were probably men who were mistaken for women by their enemies because they wore clothing which reached their feet, tied up their hair in headbands and shaved their beards, and in addition, because they did not exist during his time, most probably they did not exist in the past either.
