Ohne Titel (Blue Square), 1990

Boasting a body of work that ranges from wall drawings to prints on paper and sculptures, Sol LeWitt was an acclaimed artist linked to the Minimalism and Conceptual Art movements. LeWitt’s most notable work is arguably his Wall Drawings series – the artist developed a rigorous set of guidelines for these drawings; first they were executed in graphite, then in crayon, they were then later subject to coloured pencil and finally finished with washes of chromatically rich India Ink and bright acrylic paints – LeWitt created over 1200 of these drawings throughout his career. As a sculptor, LeWitt preferred for his creations to be referred to as structures; a largely simplified open-cube provided the basis for much of his three-dimensional work and his early structures were comprised primarily of wooden blocks with a hand-lacquered finish - LeWitt later went on to create larger structures in aluminium or steel, most of which factored in bodily proportions and measured at an approximate eye-level of around 63 inches.
