Archimedes of Syracuse is known for inventing a device that efficiently raised water for irrigation. Dr. Stephanie Dalley translated a cuneiform text from of the Assyrian king Sennacherib referencing a device like a date palm, which led her to believe the Hanging Gardens of Babylon made use of an invention comparable to Archimedes’ Screw approximately 350 years prior to its invention. In addition, certain ancient legends of the Hanging Gardens described screw-like irrigation devices similar to the Archimedes’ Screw.
