in antiquity, properly denotes a Roman army in march: in which tente, it stands contradistinguished from acies, which denoted the army in battle array; though, on some occasions, we find the two words used indifferently for each other. The Roman armies, in their marches, were divided into primum agmen, answering to our van-guard; medium agmen, our main-guard; and postrimum agmen, the rear-guard. The order of their march was thus: After the first signal with the trumpets, &c., the tents were taken down, and the baggage packed up; at the second signal, the baggage was to be loaded on the horses and carriages; and, at the third signal, they were to begin their march. First came the extraordinarii; then the auxiliaries of the first wing, with their baggage; these were followed by the legions. The cavalry marched either on each side or behind.
