When the turret was raised to the height for flooring, they laid it on the walls in such a manner that the ends of the joists were covered by the outer face of the wall, that nothing should project to which the enemy's fire might adhere. They, moreover, built over the joists with small bricks as high as the protection of the plutei and vineae permitted them; and on that place they laid two beams across, angle-ways, at a small distance from the outer walls, to support the rafters which were to cover the turret, and on the beams they laid joists across in a direct line, and on these they fastened down planks. These joists they made somewhat longer, to project beyond the outside of the wall, that they might serve to hang a curtain on them to defend and repel all blows while they were building the walls between that and the next floor, and the floor of this story they faced with bricks and mortar, that the enemy's fire might do them no damage; and on this they spread mattresses, lest the weapons thrown from engines should break through the flooring, or stones from catapults should batter the brick work. They, moreover, made three mats of cable ropes, each of them the length of the turret walls, and four feet broad, and, hanging them round the turret on the three sides which faced the enemy, fastened them to the projecting joists. For this was the only sort of defense which, they had learned by experience in other places, could not be pierced by darts or engines. But when that part of the turret which was completed was protected and secured against every attempt of the enemy, they removed the plutei to other works. They began to suspend gradually, and raise by screws from the first-floor, the entire roof of the turret, and then they elevated it as high as the length of the mats allowed. Hid and secured within these coverings, they built up the walls with bricks, and again, by another turn of the screw, cleared a place for themselves to proceed with the building; and, when they thought it time to lay another floor, they laid the ends of the beams, covered in by the outer bricks in like manner as in the first story, and from that story they again raised the uppermost floor and the mat-work. In this manner, securely and without a blow or danger, they raised it six stories high, and in laying the materials left loop-holes in such places as they thought proper for working their engines.
