"4.22.98" is a pastel work on paper by Sean Scully, the Irish American abstract painter known for his geometric compositions and exploration of color relationships. The title references the date of creation, a practice common in Scully's practice where temporal notation emphasizes the immediacy of the work's making. The piece exemplifies Scully's characteristic use of layered rectangles and stripes in pastel, creating a tactile surface that investigates light, shadow, and the interaction between warm and cool tones.
