"Regard the light" Flavin declared, "and you are fascinated - practically inhibited from grasping its limits at each end. While the tube itself has an actual length...its shadow cast from the supporting pan has but illusively dissolving ends. This waning cannot really be measured without resisting consummate visual effects. Realizing this, I knew that the actual space of a room could be disrupted and played with by careful, thorough composition of the illuminating equipment. For example if a 244cm (8ft) fluorescent lamp be pressed into a vertical corner, it can completely eliminate that definite juncture by physical structure, glare and doubled shadow. A section of wall can be visually disintegrated into a separated triangle by placing diagonal of light from edge to edge on the wall: that is, side to floor, for instance." (Dan Flavin "...in daylight or cool white" lecture given at the Brooklyn Museum School of Art, New York (18 December 1964), published in Artforum, December 1965.)
untitled (for you, Leo, in long respect and affection) 4, is one of Dan Flavin corner sculptures the artist produced in 1978 and dedicated to the legendary gallery owner Leo Castelli. Consisting of blue, green, yellow and pink fluorescent light it illuminates the dark recesses of a room, an area often neglected by artists. As one of his most intriguing works, the corner sculptures play with our perceptions of space and light. Its rich blue and golden yellow light gently mingles with the backlit green and pink to create a dramatic sunset of rainbow colors that penetrates into the deep corner of the room. The result is a very strong and independent work that not only reshapes or redefines space, it holds it together and masters it with a definitive presence that magically seems to draw in elements from the rest of the space into which it is set.
