Abstract
This study aims to reconstruct a prototype of the po robe to support the creation of a standard portrait of King Geunchogo of Baekje. Drawing upon the royal clothing culture of the Baekje period and the symbolic identity of King Geunchogo, the research examines key design elements of the robe, including its structure, color, materials, and decorative patterns. Particular emphasis is placed on the characteristics of a purple, wide-sleeved fabric interwoven with gold thread, and is analyzed within its historical and cultural context. A systematic, step-by-step methodology for the prototype's reconstruction is presented. Motifs referenced in this study are derived from recovered burial artifacts from the Hanseong period of Baekje, including the ornamented sword from Yongwon-ri Tomb No. 1, the belt from Naseong-ri Tomb No. 4, and the belt from Suchon-ri Tomb No. 1. These artifacts informed the development of textile design samples characterized by geometric and elongated patterns. The finalized textile designs were then applied to the reconstruction of King Geunchogo's robe. Natural dyeing techniques using madder root and sappanwood were employed to produce historically accurate purple dyes. This process led to the establishment of a refined color system for purple, which was subsequently incorporated into the textile production. Based on the finalized textile designs, schematic diagrams of the robe prototype were developed. In the Baekje royal court, clothing served not only as functional attire but also as a potent symbol of political authority and cultural expression. Through the reconstruction of King Geunchogo's royal robe, this study offers deeper insight into the historical and cultural significance of Baekje court dress. Moreover, the creation of a standardized portrait contributes both to the commemoration of a historical figure and to the expansion of contemporary cultural content grounded in Baekje heritage. It is anticipated that this research will serve as a foundational resource for future scholarship on ancient East Asian costume history and cultural heritage.
