First developed in 1967, Ecriture is an ongoing series of monochromes in which Park covers his canvas with a single color and manipulates the still-wet surface with repetitive, carving gestures—actions that resemble the writing of a script. While in earlier works he used a pencil or stylus to create these repetitive marks, beginning in the 1980s he introduced Hanji paper into the series, layering and scraping the pulp on the wet surface to create a unique sequence of sculptural lines that seem to float on top of the canvas. The resulting relief paintings stimulate the viewer’s perception, evoking architectural space and the phenomenology of seeing. Art historian Alexandra Munroe has characterized this work as embodying an “ecstatic minimalism.” In the early 2000s Park expanded his neutral pallet and began using vibrant colors in his works influenced by the grandeur of nature.
