Octagonal Bronze Mirror with Chinese Characters
Goryeo dynasty
Diameter 16.5cm

On the back of the bronze mirror are engraved the Chinese character ‘煌丕昌天,’
so this type of mirror is called ＇hwang-bi-chang-cheon-gyeong.＇
These mirrors are rarely excavated in China, but they are to be found in the area of the Goryeo Kingdom. Remaining mirrors of the Goryeo are larger and thicker, showing marked difference from those of China.
