Here, in one of Donald Judd's so-called "progressions," the spacing of the green elements is determined by a dual Fibonacci sequence - a mathematical progression where each number is the sum of the previous two (0, 1, 1, 2, 3, 5, and so on). Judd first arrived at this form in 1966, in a version executed in clear and purple-lacquered aluminum. When curator Brydon Smith first encountered this earlier work at the Whitney Museum of American Art, New York, in 1968, "it was love at first sight, and I couldn't take my eyes off it ... it was simple and open, yet complex ... The longer I looked the more interesting it became". In 1975, Smith organized a comprehensive survey of Judd's work at the National Gallery of Canada, for which an ambitious catalogue raisonné of the artist's painting and sculpture was published. This work was acquired with Judd's support in recognition of that exhibition.
