  1. Ropework

  2. Cavemen tied knots, so did the Incas of Peru who made knotted strings instead of written figures. They may be man’s oldest tool. Knots were important to Venetians, who maintained their empire thru Maritime strength. In the middle ages, knotting acquired religious symbolism & superstitions. By 18th century, every deep water ship was a spider’s web of rope rigging. When commercial sailing ship died, knotting seemed to have died too. Yet some people today still need knots. Rock climbers secure their ropes with care since their lives hang on them.
