“Nature has always been recorded by artists, from prehistoric cave paintings to twentieth-century landscape photography. I too wanted to make nature the subject of my work, but in new ways. I started working outside using natural materials like grass and water, and this evolved into the idea of making a sculpture by walking … My first work made by walking, in 1967, was a straight line in a grass field, which was also my own path, going ‘nowhere’. In the subsequent early map works, recording very simple but precise walks on Exmoor and Dartmoor, my intention was to make a new art which was also a new way of walking: walking as art.”

Whoever chooses to latch onto it, great; whoever doesn&#x27;t, that&#x27;s fine, too. The reaction always pales in comparison to the weight of the act of production.
