A Study on Iron Mirror Excavated from Koguryeo's Chilsilchong Tomb

The previous study on the Iron Mirror of Koguryeo studied the Iron Mirror by noting the large-scale Iron Mirror excavated from the tomb of Maseon-gu 2100 in Jilin Province, Koguryeo, and the Iron Mirror excavated from the northern tomb of Hwangnamdaechong in Gyeongju, Shilla. However, there was no specific case to determine the exact aspect of the Iron Mirror of Koguryeo. To address this issue, the Iron Mirror excavated from Chilsilchong, Yonggang County, South Pyongan Province, was investigated. Chilsilchong tomb is divided into the late 5c to 6c in terms of the structure of the remains and the excavated relics. The iron mirror excavated here is 5.6cm small, has a thin body and a small annular New attached thereto. A similar case is found in the Mandal Mountain Graves. This iron mirror was excavated from a tomb west of tomb No. 8 and has a small annular New attached to a diameter of 5cm. Considering the bronze bracelets and earthenware excavated from tomb No. 15, it is divided into the late 5c and 6c. In conclusion, the 5-6c Koguryeo Iron Mirror is characterized by a small size of about 5 to 10cm, a thin body and a small ring. This case is also confirmed in Tomb No. 2 in District III in Changnyeong, Gyeongsangnam-do. This mirror has a 7.6cm annular New. Reflecting this result, the relationship between the 5-6c range Koguryeo and Shilla should also be re-established. Among the iron mirrors excavated in China, there was no similar case of the Iron Mirror, which has a small ring measuring 5 to 10 centimeters. Through this, it was found that the small-sized and small-sized Iron Mirror was made by Koguryeo. However, over time, the Iron Mirror, which was excavated from Chilsilchon and Mandal Mountain Graves from the late 5c to the late 6c, will provide data to understand the cultural aspects of the 5c to 6c and examine the exchange relationship with Shilla after Koguryeo moved to Pyongyang.
