the snail

Two paths – double helix – rise up the Snail Mound on one side and fall gently on the other so the ascent goes up and down. Various ideas were behind this: DNA, the double staircase at Chambord that allows two people to pass without meeting, a ziggurat, the contrary movement of the giant floor-paving maze at Chartres, Tatlin's Monument to the Third International – multiple meanings that have to be decoded, slowly.
