Richard Long is an English sculptor, photographer and painter best known from his land art and conceptual art. He made his international reputation during the 1970s, already with sculptures made from indigenous materials, such as stone, wood and mud, collected from his numerous walks around the world. Stone is one of his preferred materials. Bringing together this unevenly shaped raw material in a geometric structure, his works illustrate a recurrent theme, the relationship between man and nature, as he has explained: "You could say that my work is a balance between the patterns of nature and the formalism of human, abstract ideas like lines and circles. It is where my human characteristics meet the natural forces and patterns of the world, and that is really the kind of subject of my work."
In this sculpture there are four separate groups of stones with ten stones in each. Each group makes one line and are lain in a zig-zag pattern. All the lines begin from the same end, and the lines are equally spaced and in alignment at the first stone of each line.
