"Richmond Hall, Montrose. Dan Flavin's work with fluorescent light began when he attached a single eight-foot tube to his studio wall. A year after its installation he renamed the piece The Diagonal of May 25, 1963 (once The Diagonal of Ecstasy). This name was more representational of his work with light. While art is in the eye of the beholder, Flavin was clear that his interest in fluorescent lamps was based on the fact that they were readily available and preset in color and length. The installation at Richmond Hall was his penultimate work, and was completed by his studio after his death. It was designed specifically for the space, and when you walk into the building you are immediately in the work."
