Barrack life
The gladiatorial barracks were marked by heterogeneity. Membership was constantly fluctuating, as troupes toured the local circuit. Some members survived to reach retirement; new recruits were enlisted, many of them probably unable to understand Latin.In the larger barracks, members of the same fighting-style had their own dedicated trainer, and they often bonded together in formal associations. Frequently it was a gladiator's fellows who furnished his tombstone, perhaps through membership of a burial society.
Yet gladiators must frequently have met their intimate fellows in mortal combat. Professionalism and the survival instinct would have demanded a merciless display of expertise, inculcated by the gladiator's training. Within a training-school there was a competitive hierarchy of grades (paloi) through which individuals were promoted.
The larger barracks, at least, had their own training arena, with accommodation for spectators, so that combatants became accustomed to practising before an audience of their fellows. The system meant that combat and heroic prowess were brought right into the urban centres of the Roman empire, whereas real warfare was going on unimaginably far away, on the borders of barbarism.
