Subject: knots are old! From: "RONALD BROWN" Date: Tue, 6 Feb 2007 10:10:26 -0000 I have just come across http://mc2.vicnet.net.au/home/portable/web/beads.html which those interested in knots may like to see as evidence of very old usage of cordage, namely beads. As Bednarik writes, Their roundness can be obtained only by constant checking of the shape during the final abrading process, using not just a developed sense of symmetry, but possessing a clear concept of a geometric form. It is the outcome of a distinctive abstract construct of form — a concept-mediated, geometrically perfect product. These beads date from possibly < 200,000 years ago. Ronnie
