the other as Achillia; their warlike "stage names" allude to the mythical tribe of warrior-women, and a feminine version of the warrior-hero Achilles. Otherwise, neither one is recognisable as male or female. Each is bareheaded, equipped with a greave, loincloth, belt, rectangular shield, dagger and manica (arm protection). Two rounded objects at their feet probably represent their discarded helmets. An inscription describes their match as missio, meaning that they were released; the relief, and its inscription, might indicate that they fought to an honourable "standing tie" as equals. Status and morality A number of specific legal and moral codes applied to gladiators. In an edict of 22 BC, all men of senatorial class (not including equites) down to their grandsons were prohibited from participating in the games, on penalty of infamia, which involved loss of social status and certain legal rights. In 19 AD, during the reign of Tiberius, this prohibition was extended under the Larinum Decree, to include equites, and women of citizen rank. Henceforth, all arenarii (those who appeared in the arena) could be declared "infames". This would have limited the participation of high-status women in the games, as intended, but would have made no difference to those already defined as infames, such as the low-status (non-citizen) women, freed or slave, who might serve or otherwise assist in the gladiator schools (known as Ludi) and be gladiators' wives, partners or followers (Ludia). The terms of the edict indicate a class-based, rather than a gendered prohibition. Roman morality required that all gladiators be of the lowest social classes. Emperors such as Caligula, who failed to respect this distinction, earned the scorn of posterity; Cassius Dio takes pains to point out that when the much admired emperor Titus used female gladiators, they were of acceptably low class. An inscription at Ostia Antica, marking games held there around the mid 2nd century AD, refers to a local magistrate's generous provision of "women for the sword". This is presumed to mean female gladiators, rather than victims. The inscription defines them as mulieres (women), rather than feminae (ladies), in keeping with their low social status. Juvenal describes high-status women who appear in the games as "rich women who have lost all sense of the dignities and duties of their sex." Their self-indulgence was held to have brought shame upon themselves, their gender, and Rome's social order; they, or their sponsors, undermined traditional Roman
