Bronze Mirror CT scan results

It is a bronze mirror from the Goryeo Dynasty engraved with Hwang bi-chang-cheon (brightly shining sky). The Hwang-bi-chang-cheon is a yearning originating from the Haebak pattern mirror, which was popular in the Song and Geum kingdoms of China, and is expressed as a ship sailing the sea.

According to the CT scan results, it can be seen that the appearance of the ship, such as rowing boatmen and masts, is expressed in detail. These factors show the active maritime activities of the Goryeo Dynasty.
