Gladiator
The games
Trained gladiators were expected to observe professional rules of combat. Most matches employed a senior referee (summa rudis) and an assistant, shown in mosaics with long staffs (rudes) to caution or separate opponents at some crucial point in the match. Referees were usually retired gladiators whose decisions, judgement and discretion were, for the most part, respected; they could stop bouts entirely, or pause them to allow the combatants rest, refreshment and a rub-down.
