Yoon Jae-il who concentrates on the material properties of dirt and stone through pottery work reinterpreted the man and woman geun-seok (stones in the shape of male and female sex organs) of Sammaksa. He focused on the phenomenon briquette turning into dirt when heat is applied, and he has been using briquette ashes that are thrown away at many places in Anyang when winter comes as the material for his work for a long time. Later, his interest has moved to stones he collected when he climbed mountains to broaden the artist’s work boundary. Yoon expressed the Sammaksa’s man and woman geun-seok using many stones he transformed by firing them in a kiln. He created over 50 final results by substituting countless seasons the man and woman geun-seok have endured with a special condition of 1200° C kiln, and each stone was transformed into various shapes depending on the original components of the stone. The artist realized the fact that man’s geun-seok is easily found but Anyang’s Sammaksa is the only place woman’s geun-seok is found together with that of man’s, he expressed how Yin and Yang, man and woman could live harmoniously metaphorically by adopting the 36th military tactic.
