An artistic movement that emerged in the late sixties in the United States, asserting the importance of the theoretical-mental process. The idea which the artists start from, the concept, is the entire work of art.

Sketches, notes, maquettes and conversations tend to be a part of the exhibition, but Conceptual Art is not a monolithic movement, so its manifestations are as varied as are the works of Walter de Maria, Richard Long, Gilbert and George, Joseph Kosulh and so many others.

The Dadaism of the twenties, with a tendency to dismantle the classic structure of the work, is a precursor to Conceptual Art which, depending on the concept in question, evolved during the eighties down paths as distinct as Land Art, Performance, Body Art and Process Art.

Its theoretical systematisation is in pretty short supply, with its most solid roots perhaps in the writings of LeWitt in the late sixties.

Conceptual Art has left an inedible mark on the majority of the movements currently active, which gives an idea of its true profundity.
