Michael Kidner Column in front of its own Image, 1970

In a 1996 interview, Michael Kidner indicated that 1970 was the year he deserted colour, coinciding with the development of dimensionality in his work. Kidner made a column form in 1969 manufactured from a sculpture of a wave, visualised in Column in front of its own image (1970). The imagery manifested through Kidner's interest in number theory as the solution to the characteristic of order and the formation of reality. He translated the column into a two-dimensional form to a painting by employing a structured technique of measurement and colour coding. Since Kidner did not have a reference for the point of contact between two wavy surfaces conjoining at right angles, he bent a piece of wire to replicate a wave, and then rotated it at right angles, bending it to mimic the other side. To create a painting of a three-dimensional object, he had to view the object from all angles and document its silhouette as it revolved. The complexity of the column's structure is further emphasized  through the flickering monochrome contrast between black and white.
