Religion in ancient Rome
In the early stages of the First Punic War (264 BC) the first known Roman gladiatorial munus was held, described as a funeral blood-rite to the manes of a Roman military aristocrat. The gladiator munus was never explicitly acknowledged as a human sacrifice, probably because death was not its inevitable outcome or purpose. Even so, the gladiators swore their lives to the infernal gods, and the combat was dedicated as an offering to the di manes or other gods. The event was therefore a sacrificium in the strict sense of the term, and Christian writers later condemned it as human sacrifice.
