Abstract

In order to understand the nature and interrelationship of the Sogaya group formed and grown in the southwestern Gyeongnam region of the Namgang River water system and the southern coastal region of Goseong-Masan from the early 5th to the late 6th century, this paper attempted to establish indicators of archaeological material culture and find the volatility of the central ancient tomb group. The establishment of Sogaya-style earthenware appears for the first time in an earthenware complex buried in a large wooden tomb, and it affects the distribution pattern of earthenware-style according to the growth and fluctuations of the central ancient tombs. In the Sogaya area, there are multiple central ancient tombs depending on the period, so it is different from the distribution of earthenware styles in the late Gaya countries. The large wooden tomb during the transition period, which can be seen as the tomb of the head of the Sogaya region, is a flat tubular structure using fine gravel and small stones, and a local-style earthenware complex is buried. Large wooden tombs with this structure show differences in hierarchy at the location, size of the burial site, and burial relics compared to the early burial tombs of the latter part Gaya in inland areas such as Aragaya, Daegaya, Daraguk, and Bihwagaya. As a result of presenting the growth model of the late Gaya tombs from the large wooden tombs to the central ancient tombs of the ancient tombs during the transition period, most of the large wooden tombs in the Sogaya area could not grow into the ancient tombs due to internal and external complex factors. Hapcheon Samga Ancient Tombs were assumed to be an expanded A model that grew into a central ancient tomb group equivalent to the major small countries of Gaya, and Goseong Songhak-dong Ancient Tombs were assumed to be an expanded B model that grew rapidly as a port of external exchange after the 6th century. During this period, the Sogaya area did not show any control, but Songhak-dong Ancient Tombs showed gold pieces for Baekje and Silla dressing from Daegaya and Japan harnesses, so the hierarchy and character of the group can be inferred to some extent. Although it is understood that the emergence of large wooden tombs in the Soya area, the distribution of earthenware complexes, and the variability of the graded central tombs reflect the group's internal structure and hierarchy to some extent, the interpretation of various material data should be supplemented.
