Gladiator
The games
Lightly armed and armoured fighters, such as the retiarius, would tire less rapidly than their heavily armed opponents; most bouts would have lasted 10 to 15 minutes, or 20 minutes at most. In late Republican munera, between 10 and 13 matches could have been fought on one day; this assumes one match at a time in the course of an afternoon.
