Archimedes' screw the screw and casing could be cast together as a single piece in bronze. The design of the everyday Greek and Roman water screw, in contrast to the heavy bronze device of Sennacherib, with its problematic drive chains, has a powerful simplicity. A double or triple helix was built of wood strips (or occasionally bronze sheeting) around a heavy wooden pole. A cylinder was built around the helices using long, narrow boards fastened to their periphery and waterproofed with pitch. The screw was used predominately for the transport of water to irrigation systems and for dewatering mines or other low-lying
Montes Archimedes coordinates of this range is 25.3° N, 4.6° W. The peaks of Montes Archimedes occupy an area with a maximum diameter of 163 km, although the most rugged portion of the terrain is concentrated within the central 70 km. The remainder of the peaks are scattered across the plateau, with no particular structure or pattern. Some of the peaks in this range achieve heights of up to 2.0 km, much less than those in the Montes Apenninus, for example, and none have received specific designations.
