삼국시대 복환판비의 전개 과정과 의미 —남원 두락리 고분군 출토품을 중심으로—

Abstract

The double ring bit is a bit made of a single iron rod. In this paper, the current status and development of the double ring bits excavated from the southern part of the Korean Peninsula and the Japanese Archipelago are summarized. Based on this, the archaeological significance of the double ring bits of Durak-ri, Namwon, are examined. The double ring bits of the Korean Peninsula were mainly used in Silla and Gaya from the early fifth to the late seventh centuries. They can be classified into Silla or Gaya double ring bits according to the connection method (the presence or absence of a ring); the guard in the bit of the ‘Ga’ type double ring bit reflects the change over time. It seems that the technology for producing the ‘Ga’ and ‘Na’ types, which originated in Silla, spread to Gaya from the early 6th century to the first half of the 6th century, when Silla and Gaya maintained a friendly relationship. The double ring bits excavated from the Japanese Archipelago are not much different from those of Korea. The Japanese Archipelago double ring bits have many things in common with domestic examples, such as the use of the type ‘Ga’ to ‘Da’ types. However, in the Japanese Archipelago, ‘Da’ type examples were used from an early age, and the forms that were popular in Korea and their period of use were different. There is also the ‘Ra’ type that is not observed in Korea. The double ring bit excavated from the Durak-ri tombs, in Namwon, are of the ‘Ga-3’ type, used only around the early 6th century in East Asia. Therefore, the age of the ancient tomb can be estimated based on the double ring bits. Although the ‘Ga-3’ type is of Silla origin, the excavation of the Durak-ri tombs suggests that the artifacts may have been produced locally in the Unbong Plateau through the adoption of improved production technologies from Hapcheon, which was well equipped with a high-level ironmaking technological system. The bits not only demonstrate the friendly foreign relations between Silla and Gaya from the early to the first half of the 6th century, but also illustrate the acceptance process of the latest harness manufacturing technology from Hapcheon.
