Chronology of Grayish Pottery in the Lower Nakdonggang River

In this paper, as part of the basic work to examine the establishment and development process of various groups during the Proto-Three Kingdoms period in the Nakdong River lower region before the establishment of Gaya, a chronology of regional Grayish Pottery in the Nakdong River lower region is established through regional attribute analysis and formal classification of Grayish Pottery. I wanted to come up with a plan. As a result, the level of Grayish Pottery was set at level 6 in the Miryang area, level 8 in the Changwon area, and level 12 in the Gimhae area. By examining the morphological similarities and regional characteristics of Wajil pottery at each stage in each region, the early Grayish Pottery was synthesized into 8 stages and the late Grayish Pottery into 5 stages, and a chronological plan with a total of 13 stages was presented. Due to differences in the selection of properties and forms and differences in duration observed during this series of analysis processes, Grayish Pottery changes differently in each region, and the subtle differences in form between similar types of the same period were understood as regional characteristics of Grayish Pottery. Regionality refers to the differences between the production and group of Grayish Pottery at the regional or heritage level, and was interpreted as having the potential to be interpreted as the growth and integration of the Grayish Pottery. The age of each stage presented absolute age data such as the Korean style scriptures confirmed in the lower reaches of the Nakdong River, and the age of each stage was assigned by referring to existing research results. At the beginning of the early Grayish Pottery stage, early Grayish Pottery began to be produced mainly in Dahori, Changwon, and Gyodong, Miryang. In the later period, production of early Grayish Pottery began to decrease in Dahori, Changwon, and Gyodong, Miryang, and production of early Grayish Pottery began in earnest, centering on Gimhae, resulting in a transition to the late Grayish Pottery stage. In other words, in the latter part of the Early Grayish Pottery phase, the production of Early Grayish Pottery was reduced at the ruins located in the current inland, and the full-scale production of Early Grayish Pottery was centered on the ruins adjacent to the southern coast, and there was a transition to late Grayish Pottery. The explanation was combined with research results related to sea level fluctuations during the Proto-Three Kingdoms period.
