From the middle of these ropes a wooden arm rises obliquely, pointed upward like the

v2.p.329
pole of a chariot,[*](I.e. when the horses are not harnessed to it.) and is twined around with cords in such a way that it can be raised higher or depressed. To the top of this arm, iron hooks are fastened, from which hangs a sling of hemp or iron. In front of the arm is placed a great cushion of hair-cloth stuffed with fine chaff, bound on with strong cords, and placed on a heap of turf or a pile of sundried bricks; for a heavy machine of this kind, if placed upon a stone wall, shatters everything beneath it by its violent concussion, rather than by its weight.

Then, when there is a battle, a round stone is placed in the sling and four young men on each side turn back the bar with which the ropes are connected and bend the pole almost flat. Then finally the gunner, standing above, strikes out the pole-bolt, which holds the fastenings of the whole work, with a strong hammer, thereupon the pole is set free, and flying forward with a swift stroke, and meeting the soft hair-cloth, hurls the stone, which will crush whatever it hits.

And the machine is called tormentum as all the released tension is caused by twisting (torquetur); and scorpion, because it has an upraised sting; modern times have given it the new name onager, because when wild asses are pursued by hunters, by kicking they hurl back stones to a distance, either crushing the breasts of their pursuers, or breaking the bones of their skulls and shattering them.

Now we shall come to the ram. A tall fir or mountain ash is selected, to the end of which is fastened a long, hard iron; this has the appearance of a projecting ram’s head, and it is this shape which

v2.p.331
has given the machine its name. This is suspended between ironbound beams running across on both sides, so that it hangs from a third beam like the pan of a balance. Then a number of men, as great as the length of the pole permits, draw it back and then shove it forward again with powerful blows, just as a ram charges and retreats, to break everything in its way. As this is renewed with the force of a repeated stroke of lightning,[*](The ancients believed that a stroke of lightning returned to the sky, doing damage as it came and as it went. Cf. Lucan, i, 156.) buildings are cracked and shattered as the structure of their walls is destroyed.

If this kind of engine is worked with full vigour, the strongest cities, after their walls have been stripped of defenders, are laid open, and the siege is thus brought to an end.

In place of these devices of rams, which, because they are now so frequent, are in less esteem, a machine is made, well known to the historians, which we Greeks call helepolis.[*](City-taker. The descriptions of Diod. xx. 48 and 91, and Athen. v. p. 206 d, are of a more powerful machine, including lofty towers.) It was through the constant employment of this engine that Demetrius, the son of King Antigonus, after taking Rhodes and other cities gained the name of Poliorcetes.[*](Besieger of cities.)

It is built in the following manner: a huge mantlet[*](Or tortoise-shed.) is constructed of strong planks of great length fastened together with iron nails, and covered with ox-hides and hurdles of green twigs; and over these is spread mud, in order to protect it from fire and falling missiles.
