 | | But a real engineering achievement was in digging the conduit simultaneously from two ends, especially considering the substantial distance from the spring to the reservoir and the depth from the surface of the rock to the conduit beneath. |
 | | And when the tunnel was driven through, the quarrymen hewed (the rock), each man toward his fellow, axe against axe; and the water flowed from the spring toward the reservoir for 1,200 cubits, and the height of the rock above the head(s) of the quarrymen was 100 cubits. |
 | | Even in modern times, with all the developed surveillance methods, road tunnels running under mountain passes, when dug from two ends with the two teams not bypassing each other, are a cause of celebration—a deviation of even a fraction of a degree would result in a failure. |
