소가야지역의 횡혈식석실 수용과 특징 -내산리고분군의 횡혈식석실을 중심으로-

Abstract

The current study analyzed the structures of horizontal chambers of Naesan-ri Old Tombs in Goseong that have actively been studied recently and compared them to the old tombs with previously studied vertical coffins to identify their characteristics. Horizontal chambers were introduced to Naesan-ri Old Tombs in the second quarter of the 6th Century as a result of comparing them with the horizontal chambers of other Gaya regions. After creating the primary mounds, which are the unique characteristic of Naesan-ri Old Tombs, burial facilities were created as a civil works method to overcome the weakness of stone materials, but the construction methods of old tombs changed after the acceptance of horizontal chambers. The stone chamber and mound are created together on contacted surface and the thickness of walls was made thicker than the walls of horizontal chamber to bear the weight of cover stone and upper part. The horizontal chambers of Naesan-ri Old Tombs have many things in common with the horizontal chambers of southern Gaya regions, such as the rectangular form, central chronology, flat ceiling, and burial of corpses in wooden coffins, but the doors were characteristic. The doors were inspired by Japanese stone chambers. The horizontal chambers of Naesan-ri Old Tombs combined the local old tomb construction method, the horizontal burial method of Baekje, and the doors of Japanese stone chambers.
