Archimedes by John Timbs

The ancients attribute to Archimedes more than forty mechanical inventions�among which are the endless screw; the combination of pulleys; an hydraulic organ, according to Tertullian; a machine called the helix, or screw, for launching ships; and a machine called loculus, which appears to have consisted of forty pieces, by the putting together of which various objects could be framed, and which were used by boys as a sort of artificial memory.
