S ongsan-ri Tomb No. 29 represents a merging of the use of brick with the traditional stone chamber tomb architecture, illustrating that the social and cultural aspects had direct impact on the burial culture of the time. The tombs of Songsan-ri have been established as follows: Tombs No. 1 to No. 4 located along the northeast hill belong to the line of King Munju to King Samgeun; the Tomb of King Muryeong and Tombs No. 5, No. 6, No.
29, located along the southwest hill belong to the line of King Muryeong. An examination of their construction order, based on location, structural features, and artifacts (in particular, coffin nails), can be suggested as follows: Tombs No. 2 to No. 4 were first built, followed by Tomb No. 1, the Tomb of King Muryeong, and Tombs No. 6, No. 5 and No. 29, in that order.
This study then reviewed the temporal position and genealogy of Tomb No. 29 by putting together the survey reports dating to the period of Japanese Occupation and the recent re-excavation survey of the tomb. Important clues for figuring out the time period of construction were found in the coffin nails with flower-shaped head, semi-globular head, and square head excavated in Tomb No. 29. It is presumed that the coffin nails with flower- shaped and square heads were used during the Ungjin period, whereas coffin nails with semi-globular heads were seemingly produced in the middle of the sixth century, around the time of the relocation of the capital to Sabi. This suggests that wooden coffin B from Tomb No. 29, featuring a combination of coffin nails with semi-globular and square heads, was added to the tomb in the middle sixth century, in the early part of the Sabi period.
Finally, this study explored the identity (geneaolgy) of the deceased buried in Tomb No.
29. It was suggested that one of King Muryeong’s kin was buried in the tomb at the last stage. In considering together various lines of evidence previously discussed, it was established that after a royal female had passed away at the end of Ungjin period, was put into wooden coffin A, and placed upon the western coffin bed, a royal male had passed away in the middle of the sixth century, the early Sabi period, was put into woodden coffin B, and placed upon the eastern coffin bed.
