Again in the field a bombard of 100-pound range is far better than a passavolante, because the former with its bounces damages the enemy greatly, whereas the passavolante — or rather its ball, being of lead — after the first shot, because it is heavy, does not bounce, and for this reason is less useful.
If you set an arrow fixed almost in balance upon a little stone that is nearly about to fall, you will see that a great bombard, fired ten miles away from that arrow, will make the said arrow fall — or the stone balanced upon it — through the trembling of the earth.
Again, if you fire a small bombard (bombardella) in a courtyard surrounded by suitable walls, whatever vessel is in that place, or paper-covered windows, all will break at once, and the roofs will lift somewhat from their supports, the walls and the ground will shake like a great earthquake, and the spiders' webs will all fall and the small animals will die, and every nearby body that has air within it will at once suffer harm and some damage. But the said bombardella must be fired without its tube (tromba); and if it is to be used like a cortaldo, this will make women and every pregnant animal miscarry; the chicks will die in the eggs.
