Spiral Sunday #13 – a rope is a spiral, right?

Spiral Sunday today shows a detail from a cast iron bridge that I photographed recently in Bristol.  As far  as I can gather the bridge commemorates the local rope making industry, which was vital for the shipping that used this port.  To make ropes like this you twist the fibres, forming a helix; which is, of course, a long spiral.  Right?

  1. I think it’s even better than you realise. Rope is twined first one way and then the other, so it is multiple helixes.
