  • THE SCREW OF ARCHIMEDES Archimedes of Syracuse, when he was in Egypt, invented a machine for pumping bilge water out of the holds of ships.   . . .  A curious model of such an instrument, probably of the late Ptolemaic period, has been found in Lower Egypt. It consists of a terra-cotta cylinder with a screw inside it, 10 inches long and 4-1/2 inches in diameter.

      It's amazing that this was the modern water pump back then.
