Archimandrite

Abbot in Greek Ch. Arch i me des, 287-212 B.C. Greek mathematician of Syracuse: only one of the ancients who added anything of value to the theory of mechanics and to hydrostatics. He first discovered the truth that "any body immersed in a fluid is buoyed upward with a force equal to the weight of the displaced fluid." By this law he discovered the fraud practiced on King Hiero by a goldsmith, whom he had ordered to make a crown of pure gold. The method occurred to him as he was entering the bath, and he is said to have run home naked, exclaiming, "Eureka! (I have found it!)" He boasted that he could move the world if he had a fulcrum for his lever. He invented the endle screw and the ARCH I ME DES' SCREW (q.v.). While in the act of drawing geometrical figures in the sand, he was killed by a Roman soldier.
