These bronze mirrors were found from Royal Tomb of King Muryeong, the 25th King of Baekje, located in Geumseong-dong, Gongju, Chungcheongnam-do, South Korea. The bronze mirror named ‘Cheongdong Sinsu Mirror’ is modeled after a Chinese mirror named ‘Banggyeokgyu Gumun Mirror’ of Later Han. The mirror has an inscription and seminude figure as can be seen in many mirrors from the Later Han period. The bronze mirror named ‘Uijasonsudae Mirror’ is designed after the ‘Chinese Sudae Mirror’ of the Han period. Arranged around the knob at the center are nine protuberances, within which are circles and seven more protrusions. On the rim is an illegible inscription. The third mirror named ‘Sudae Mirror,’ engraved with animal figures, is also an imitation of the Chinese mirrors made during the Han period. However, the lines are bolder and the patterns are less elaborate than the other two.
