          hydrostatics, application of pi
          in geometry and invention of
          numerous war machines made
          him revered both in his day and
          centuries later. His weapons of
          war were vital to the defence of
          Syracuse when it was besieged
          by the Romans from 214 to 212
          BCE, but the city eventually fell
          and the great man was slain.

         GENIUS MATHEMATICIAN
         SYRACUSE, SICILY, 287-212 BCE




        01 INVENTOR OF SUPERWEAPONS

        While living in Syracuse he designed
        numerous weapons to defend the city
        from attackers, including an elaborate

        ‘death ray’ designed to concentrate
        the rays of the Sun onto enemy ships,
        setting them alight. He also developed
        effective catapults and a ‘giant claw’
        that would latch onto the hull of a ship
        and cause it to capsize.
