Sir Richard Julian Long, CBE, RA (born 2 June 1945) is an English sculptor and one of the best-known British land artists. His work has proven to be revolutionary as it has changed how society views sculpture. His work has influenced the boundaries of sculpture to not be limited to only "traditional" materials and to be able to use alternative materials in his work. Not only is he using alternative materials such as rock and earth, but he also changed what art is, as the actual art piece can be the process of creating the art itself.
In his work, often cited as a response to the environments he walked in, the landscape would be deliberately changed in some way, as in A Line Made by Walking (1967)
