Typically, a windlass consists of a horizontal cylinder (barrel), which is rotated by the turn of a crank or belt. A [[winch]] is affixed to one or both ends, and a cable or rope is wound around the winch, pulling a weight attached to the opposite end. The Greek scientist [[Archimedes]] was the inventor of the windlass.<ref>{{cite book |last=Sarton |first=George |author-link=George Sarton |year=1959 |title=A History of Science |volume=2 |chapter=Part 2, Hellenistic Science and Culture in the Last Three Centuries B.
