Lines and circles are the two shapes which recur in Richard Long's art. Although his work is based around walks made all over the world, Long also brings nature into the gallery by making sculptures using natural materials. In a world which is becoming increasingly urbanised and detached from nature, he makes the viewer aware of nature and its importance in our lives. Set out like a path, this fifteen metre-long line of willow sticks reflects the journey taken by the artist to collect the wood and design the sculpture. Unlike his sculptures made with stone, the space between the sticks gives this work a light, airy quality.
