On the Archaeological Implications of Koguryo Metal Vessels Buried in Silla’s Wooden Chamber Tombs with Stone Mounds
A new study reveals that metal vessels found in Silla’s wooden chamber tombs with stone mounds (jeokseokmokgwak-bun) bear a significant relationship to Koguryo, suggesting these items were not only functional but also held ceremonial significance tied to food offerings. The composition of these vessels mirrors those found in Koguryo’s large stone-mound tombs and aligns with depictions in Koguryo murals, indicating a shift in burial practices that reflects changing political dynamics between Koguryo and Silla. Initially, Koguryo-style metal vessels were prestigious artifacts used in food offering rituals, but their prevalence waned over time as personal utensils shifted to lacquerware, wood, and earthenware. This transformation is linked to the evolving relationship between the two kingdoms and changes in funeral customs during the period.
Contribution to the Understanding of Mural Painting Techniques of Jinpari Tomb No. 4 of the Complex of Koguryo Tombs, World Heritage
A groundbreaking analysis of the mural paintings in Jinpari Tomb No. 4, part of the UNESCO-listed Complex of Koguryo Tombs, has revealed the precise materials and techniques used by ancient Koguryo artisans over 1,500 years ago. Researchers identified malachite as the green pigment through high copper content analysis, distinctive crystal structures, and X-ray diffraction (XRD) patterns, confirming its use in the paintings. The study further uncovered that the ground layer consisted of earthen materials rich in calcium, aluminum, silicon, potassium, magnesium, and iron, while the lime layer contained limestone-derived calcium carbonate. These findings, based on chemical composition and microstructural analysis, provide unprecedented insights into the sophisticated mural painting techniques employed during the Koguryo period.
An Archaeological Perspective on Ancient East Asian Royal Tombs
Archaeological analysis of East Asian royal tombs reveals that the construction of massive royal tombs, such as those found in Northern Wei (China), Gaya (Korea), and Wa (Japan), was a shared process across different historical contexts, driven by the establishment and growth of royal authority. The study highlights that the Northern Wei dynasty, despite its nomadic origins, began constructing large tombs in the late 5th century, likely as part of sinicization policies and in response to neighboring regimes like Koguryo and the Rouran Khaganate. In Gaya, the decline of state power and changes in royal lines are inferred from the absence of new large tombs after the 4th century, while Daegaya's tombs suggest a social development comparable to Silla and Baekje. In Wa (Japan), the frequent relocation of tomb construction sites indicates dispersed royal authority and instability in hereditary succession. The research combines in-situ investigations with historical analysis to uncover these patterns, providing insights into the political and social dynamics of ancient East Asian societies.
