Res Gestae

But when the wicker mantlets[*](By which the besiegers were protected.) went confidently on and were already close to the walls, great jars fell from above along with millstones and pieces of columns, by the excessive weight of which the assailants were overwhelmed; and since their devices for protection were rent asunder with great gaps, they made their escape with the greatest peril.

Therefore on the tenth day after the beginning of the siege, when the waning hope of our men was causing general dejection, it was decided to bring into action a ram of great size, which the Persians, after formerly using it to raze Antioch, had brought back and left at Carrae. The unlooked-for sight of this and the skilful manner in which it was put together would

And after this they lacked neither rash courage nor good judgement. For although the ram, which was old and had been taken apart for ready transportation, was being set up with all skill and with every exertion of power, and was protected by the besiegers with a mantlet of great strength, yet the artillery and the showers of stones and sling-shots continued none the less to destroy great numbers on both sides. The massive mounds too were rising with rapid additions, the siege grew hotter every day, and many of our men fell for the reason that, fighting as they were under the emperor’s eye, through the hope of rewards and wishing to be easily recognised they put off their helmets from their heads and so fell victims to the skill of the enemy’s archers.
