back the lever to the ground; then the grapple being suddenly disengaged, the ship falling as it were from the wall, was, by these means, to the utter consternation of the mariners, dashed in such a manner against the water, that even if it fell back in an erect position it took in a great quantity of water.  Thus the attack by sea was foiled, and their whole efforts were directed to an attack by land with all their forces.  But on this side also the place was furnished with a similar array of engines of every kind, procured at the expense of Hiero, who had given his attention to this object through a course of many years, and constructed by the unrivalled abilities of Archimedes.  The nature of the place also assisted them; for the rock which formed the foundation of the wall was for the most part so steep, that not only materials discharged from engines, but such as were rolled down by their own gravity, fell upon the enemy with great force; the same cause rendered the approach to the city difficult, and the footing unsteady.  Wherefore, a council being held, it was resolved, since every attempt was frustrated, to abstain from assaulting the place, and keeping up a blockade, only to cut off the provisions of the enemy by sea and land.
