Spendius returned to them untiringly. It was he who stretched the skeins of the ballistas. In order that the twin tensions might completely correspond, the ropes as they were tightened were struck on the right and left alternately until both sides gave out an equal sound. Spendius would mount upon the timbers. He would strike the ropes softly with the extremity of his foot, and strain his ears like a musician tuning a lyre. Then when the beam of the catapult rose, when the pillar of the ballista trembled with the shock of the spring, when the stones were shooting in rays, and the darts pouring in streams, he would incline his whole body and fling his arms into the air as though to follow them. The soldiers admired his skill and executed his commands. In the gaiety of their work they gave utterance to jests on the names of the machines. Thus the plyers for seizing the rams were called “wolves,” and the galleries were covered with “vines”; they were lambs, or they were going to gather the grapes; and as they loaded their pieces they would say to the onagers: “Come, pick well!” and to the scorpions: “Pierce them to the heart!” These jokes, which were ever the same, kept up their courage. Nevertheless the machines did not demolish the rampart. It was formed of two walls and was completely filled with earth. The upper portions were beaten down, but each time the besieged raised them again. Matho ordered the construction of wooden towers which should be as high as the towers of stone. They cast turf, stakes, pebbles and chariots with their wheels into the trench so as to fill it up the more quickly; but before this was accomplished the immense throng of the Barbarians undulated over the plain with a single movement and came beating against the foot of the walls like an overflowing sea. They moved forward the rope ladders, straight ladders, and sambucas, the latter consisting of two poles from which a series of bamboos terminating in a moveable bridge were lowered by means of tackling. They formed numerous straight lines resting against the wall, and the Mercenaries mounted them in files, holding their weapons in their hands. Not a Carthaginian showed himself; already two thirds of the rampart had been covered. Then the battlements opened, vomiting flames and smoke like dragon jaws; the sand scattered and entered the joints of their armour; the petroleum fastened on their garments; the liquid lead hopped on their helmets and made holes in their flesh; a rain of sparks splashed against their faces, and eyeless orbits seemed to weep tears as big as almonds. There were men all yellow with oil, with their hair in flames. They began to run and set fire to the rest. They were extinguished in mantles steeped in blood, which were thrown from a distance over their faces. Some who had no wounds remained motionless, stiffer than stakes, their mouths open and their arms outspread.
