Richard Long's work is difficult to categorize. Similar to Alexander Calder, who introduced new ideas about the meaning of sculpture, Richard Long has added concepts about time, space, and chance to his two- and three-dimensional works. Long has taken many walks in hundreds of miles of landscape around the world. He records his experiences in maps, photographs, and texts of the places he has visited. He also removes stones and other materials from the sites he has walked. Long then arranges them in circles, as well as other geometric forms.
"Georgia Granite Circle", a work actually comprised of some seven tons and several thousand specimens of marble (misnamed Georgia granite), is made according to the artist's written directions. Each time it is moved, the rocks are reconfigured; the work is never the same.
