Kim Hongjoo, one of representative painters in Korea, was a member of the conceptual art group, SㆍT Group established in the 1960s. The artist presented the concept of a window or a mirror frame in his early stage of activity when he set the canvas as a frame of perception to view the world, and he also painted rural landscapes by borrowing the perspective originated from ancient oriental painting. Afterwards, he portrayed the petals and leaves with delicate touches of brush strokes. Nevertheless, his petals are not the literal depiction of petals themselves. They rather symbolize the world as a perfect unity, in other words, the existence itself or the painting itself. Over time, both the petals and leaves gradually disappear from the canvas and detailed portrayals are accumulated to develop into painting consisting of a single transparent surface. The recent work of Kim Hongjoo is a masterpiece drawing closer to the absolute state of painting. It precisely reveals the true value of“existence and non-existence are born due to their mutual relativity (you wu xiang sheng),”which is intended to embrace everything despite the total absence of expressions.
