Since the period of Japanese occupation, the Twin Tombs(雙陵), in Iksan(益 山), were recognized as the royal tombs of the late Baekje(百濟) period. It was impossible to determine the owner of the tomb at the time of excavation in 1917, but the Great King’s tomb(大王陵) has generally been regarded as the tomb of King Mu(武王) and the Small King’s tomb(小王陵) to be that of his queen consort.
In 2017, the Great King’s tomb was excavated once again and a previously unknown wooden box containing bones was found within. BNRICH undertook the present research on these bones since, if they belong to the tomb’s owner, they can present a definitive clue to establishing whether or not King Mu was indeed buried in this tomb.
The human bones found in the Great King’s tomb were identified as representing the skeleton of one person. It was identified as a male skeleton based on a non-metric test of the humerus and a metric test of the talus and femur. The results of the analysis of the degree of degeneration of the symphyseal surface and the suricular surface of the hip bone using a test method known to be highly accurate in age estimation, the deceased was confirmed to have been an elderly individual.
The height calculated from the partial measured value of the femur was 161.0~170.1cm. DISH (Diffuse idiopathic skeletal hyperostosis), known to be present predominantly in elderly males, was identified and degenerative extraspinal ossification was also observed. Using radiocarbon dating, the time of death is inferred to be sometime from the early to mid-seventh century.
Based on the results of this study, it can concluded that previous interpretations that identified the Great King’s tomb as the tomb of King Mu were of high probability.
