As legend has it, the Archimedes screw, the first ever mechanical pump, as invented by the Greek mathematician Archimedes in the 3rd century BC, was initially developed to remove bilge water from ships. However, it was also deployed as a means of transferring water from a low-lying body of water into an irrigation canal. Perhaps most famous of all was its use in the Hanging Gardens of Babylon.
