Can an idea be art? Sol LeWitt, considered a founder of Conceptual Art, believed that it could. For LeWitt, ideas and thought processes involved in creating art are as important as the finished work. This etching is part of a 12-image series that examines and expands the form of a cube. LeWitt devised rules of geometry to inform the shapes that can be created from a cubic rectangle. His strong use of color was influenced by Italian Renaissance art as well as a rigorous, career-long exploration of color and hue. By asserting the importance of the concept behind a work of art, and challenging the dominant thinking around what art could and should be, LeWitt influenced generations of artists.
