SUH Seungwon (1942- ) has continuously sought the unification of formal elements while delving into the coherent theme of “simultaneity” for about five decades. He played a pivotal role in the development of contemporary Korean art by presenting a theoretical framework for Korean modernism through his active engagement with such art groups as “Origin” and “AG” since the prevalence of Korean Informel. Here simultaneity refers to making the invisible visible, to the simultaneous manifestation of what happens in the world of nirvana in this world, and to “the pursuit of identical and equal time and space”. His works are the inquiries into strict formal orders and spaces and seek to achieve the simultaneous representation of the operations and spiritualities of physical time. Simultaneity 06-1103 (2006) epitomizes Suh’s lenient transition around the 1990s from geometric stringency to spatial expansion.
