Archimedes Screw
or Archimedean screw, or screwpump, is a machine historically used for transferring water from a low-lying body of water into irrigation ditches. It is one of several inventions and discoveries reputed to have been made by Archimedes, but as some researchers suggest, some form of this mechanism may have been used earlier by Sennacherib, King of Assyria, in the 7th century BC.
