most prominent Amazon queens were: Otrera, daughter of the nymph Harmonia and god of war, Ares. She is the mother of Hippolyta, Antiope, Melanippe, and Penthesilea and the mythical founder of the Temple of Artemis in Ephesus. Hippolyte, daughter of Otrera and Ares. She is part of the Theseus and Heracles myths, in which Antiope is her sister. Alcippe, the only Amazon known to have sworn a chastity oath, belongs to her entourage. Penthesilea, who kills her sister Hippolyte in a hunting accident, comes to the aid of the hard-pressed Trojans with her warriors, is defeated by Achilles, who falls in love with the dying woman. Myrina, who leads a military expedition in Libya, defeats the Atlanteans, forms an alliance with the ruler of Egypt, and conquers numerous cities and islands. Thalestris, the last known Amazon queen. According to legend, she meets the Greek conqueror Alexander the Great in 330 BC. Her home is the Thermodon region, or, variably, the Gates of Alexander, south of the Caspian Sea. Various authors and chroniclers Quintus Smyrnaeus Quintus Smyrnaeus, author of the Posthomerica lists the attendant warriors of Penthesilea: "Clonie was there, Polemusa, Derinoe, Evandre, and Antandre, and Bremusa, Hippothoe, dark-eyed Harmothoe, Alcibie, Derimacheia, Antibrote, and Thermodosa glorying with the spear." Diodorus Siculus Diodorus Siculus lists twelve Amazons who challenged and died fighting Heracles during his quest for Hippolyta's girdle: Aella, Philippis, Prothoe, Eriboea, Celaeno, Eurybia, Phoebe, Deianeira, Asteria, Marpe, Tecmessa, Alcippe. After Alcippe's death, a group attack followed. Diodorus also mentions Melanippe, who Heracles set free after accepting her girdle and Antiope as ransom. Diodorus lists another group with Myrina as the queen who commanded the Amazons in a military expedition in Libya, as well as her sister Mytilene, after whom she named the city of the same name. Myrina also named three more cities after the Amazons who held the most important commands under her, Cyme, Pitane, and Priene. Justin and Paulus Orosius Both Justin in his Epitome of Trogus Pompeius and Paulus Orosius give an account of the Amazons, citing the same names.

She shared power with her sister Antiope, but she was engaged in war abroad when Heracles attacked. Two of Antiope's sisters were taken prisoner, Menalippe
