The stepped tiers of the Colosseum cavea presented a a microcosm of the hierarchical Roman social structure. The level closest to the arena, the podium, was reserved for the elite at the pinnacle of society, the senators in their purple/crimson-bordered togas, with special boxes for the emperor and his family, and for the Vestal Virgins. The next level, the maenianum primum, was occupied by the equestrians (equites) with their tunics with narrow purple/crimson stripes. The third and largest level, the maenianum secundum imum, held the general body of Roman citizens, draped in their undyed off-white togas, further subdivided according to other criteria (soldiers, married citizens, boys and their tutors, guilds, etc.). The pullati ("those dressed in dark clothing," i.e. all those not wearing togas) were packed into highest level, the maenianum secundum summum, including foreigners, non-citizen freedmen, slaves, and other groups of the urban poor. Finally, set off from the open tiers of seating by a colonnade, the maenianum summum in ligneis provided wooden bleachers for women from all classes, providing a visual symbol of the conception of women as simultaneously part of Roman society and set apart from the structural divisions of Roman social order.
