Amazons were the mythological female warriors who, under the command of their queen, lived apart from men. In The Argonautica, Apollonius Rodius gives an account of the amazons, mentioning that they were the daughters of the gods Ares and Harmonia.

The representation might also be referred to the widespread practice of having female combatants during the Roman Empire. Female gladiators were indeed very rare, but at the same time well-documented.
