The question is whether this device actually existed and worked or if the later historians embellished the tales. Translation by Ian Scott-Kilvert in Makers of Rome: Nine Lives, Penguin Classics, New York, 1965. Often there would be seen the terrifying spectacle of a ship being lifted clean out of the water into the air and whirled about as it hung there, until every man had been shaken out of the hull and thrown in different direction, after which it would be dashed down empty upon the walls. Parallel Lives: Marcellus At the same time huge beams were run out from the walls so as to project over the Roman ships: some of them were then sunk by great weights dropped from above, while others were seized at the bows by iron claws or by beaks like those of cranes, hauled into the air by means of counterweights until they stood upright upon their sterns, and then allowed to plunge to the bottom, or else they were spun round by means of windlasses situated inside the city and dashed against the steep cliffs and rocks which jutted out under the walls, with great loss of life to the crews. For example, Plutarch wrote: Plutarch (45 CE -120 CE) Others had a claw or grappling hook, which grabbed hold of the rigging or rails of a galley, raising it, shaking it and capsizing it.

Plutarch, Polybius and Livy all speak of huge beams that could be swung out over the walls and some of these dropped huge weights, punching holes through the ships and sinking them. The Archimedes Claw is one of the most notorious of his inventions, designed to repel the powerful fleet of Roman galleys from the seaward walls of Syracuse. With a name like that, it is asking to be built and tested, something that the Mythbusters could not resist! The Archimedes Claw His other alleged idea was using mirrors or polished shields to focus sunlight into a point and set fire to wooden ships, an invention commonly referred to as the Archimedes Death Ray. These include the notorious Archimedes Claw, which used a crane and grappling hook to reach down and grab Roman galleys, eventually capsizing them. Some of these titanic machines seem to have been stone throwers or large crossbows, but the ancient historians tell of other inventions.

Jeanne Bendick, through text and pictures, manages to bring to life this famed mathematician who so influenced all later science.

In a biography full of lively incidents, Bendick introduces Archimedes, mathematician, inventor, and great pioneer of modern scientific method. And his original work as a geometrician gave modern geometry many of its basic tools. With such inventions as the compound pulley and the Archimedean screw he provided the foundation for the sciences of mechanics and hydrostatics. Not reproduced with Optical Recognition software.
