Battering-ram

In antiquity, a military engine used to batter and beat down the walls of places besieged. There were two different kinds of battering-rams, one rude and plain, the other compound. The former seems to have been no more than a great beam, which the soldiers bore on their arms and shoulders, and with one end of it, by main force, a ailed the walls. The compound ram was a large beam with a head of iron, which was sometimes made to resemble the head of a ram. It was suspended by ropes to a beam supported by posts, and balanced so as to swing backwards and forwards, and was impelled by men against the wall. These rams were sometimes 120 feet in length.
