arm he carried a shield of a peculiar shape, and in his right hand he wielded a staff with which he smote on the shield till it rang again.(567) Such weapons in priestly hands may be turned against spiritual foes; in the preceding pages we have met with many examples of the use of material arms to rout the host of demons who oppress the imagination of primitive man, and we have seen that the clash and clangour of metal is often deemed particularly effective in putting these baleful beings to flight.(568) May it not have been so with the martial priests of Mars? We know that they paraded the city for days together in a regular order, taking up their quarters for the night at a different place each day; and as they went they danced in triple time, singing and clashing on their shields and taking their time from a fugleman, who skipped and postured at their head.(569) We may conjecture that in so doing they were supposed to be expelling the powers of evil which had accumulated during the preceding year or six months, and which the people pictured to themselves in the form of demons lurking in the houses, temples, and the other edifices of the city. In savage communities such tumultuous and noisy processions often parade the village for a similar purpose. Similarly, we have seen that among the Iroquois men in fantastic costume used to go about collecting the sins of the people as a preliminary to transferring them to the scapegoat dogs; and we have met with many examples of armed men rushing about the streets and houses to drive out demons and evils of all kinds.(570) Why should it not have been so also in ancient Rome? The religion of the old Romans is full of relics of savagery.
