Archimedes' screw
Also called the Archimedean screw or screwpump, is a machine historically used for transferring water from a low-lying body of water into irrigation ditches. The screw pump is commonly attributed to Archimedes on the occasion of his visit to Egypt, but this tradition may reflect only that the apparatus was unknown to the Greeks beforeHellenistic times and introduced in his lifetime by unknown Greek engineers,although some writers have suggested the device may have been in use in Assyria some 350 years earlier.
