'Dirac from the album Diam' by Victor Vasarely is a serigraph measuring 70 × 62 cm, hand-signed and from a numbered edition. A large torus-like ring dominates the square composition, its curved surface rendered in a shifting grid of rounded rectangles across four quadrants — yellow-gold upper-left, violet upper-right, green lower-left, and grey-yellow lower-right. The warping of the grid lines generates a convincing illusion of a concave tunnel receding into darkness at its centre. This optical mechanics is the core of Vasarely's practice: as the leading figure of Op Art, he built visual depth from nothing but colour, geometry, and systematic repetition — no perspective lines, no shading in the traditional sense. The 1988 date places 'Dirac' within his mature print output, where serigraph's capacity for flat, saturated colour made it an ideal vehicle for works demanding exact chromatic calibration across hundreds of repeated units.
