The Bustuarii (sing. bustuarius) were a kind of gladiators in Ancient Rome, who fought about the bustum, or pile of a deceased person, in the ceremony of his obsequies. At first, the practice was to sacrifice captives on the tomb, or at the bustum of their warriors: instances of which are in Homer, at the obsequies of Patroclus, and among the Greek tragedians. Their blood was supposed to appease the infernal gods, and render them propitious to the remains of the deceased. In later ages, this custom appeared too barbarous; and in lieu of these victims, they appointed gladiators to fight, whose blood, it was supposed, might have the same effect.
