In Korea, it is almost certain that the ancient Baekje buildings used Odaruki. In the Joseon era, Guengnakjeon of Hwaamsa is known as the only building that uses Odaruki in Korea. As for the Goryeo era, mainly relics and paintings are being studied, but the excavated sites has not been studied. Based on research results of studies on the Odaruki of relics and paintings, this paper studies on the Odaruki of the buildings in the Goryeo era by examining also including the excavated sites.
From the Odaruki seen in the relics and paintings of the Goryeo era, it is believed that the Odaruki corresponding to the same period of China was also used during the Goryeo era in Korea. And it seems that the technique of the Odaruki of ancient times also took over until the Goryeo era. The Odaruki since ancient times is seen in Gilt-bronze Offering Pagoda (Fig. 1) and Mirror with Figures and Pavilion in a Landscape (Fig. 2) . And, the Odaruki of the newly brought Dapo architecture is seen in Gilt-bronze Miniature Buddhist Triad Hall (Fig. 3). In addition, the Odaruki used in Liao and Jin buildings was found in the nine-storied pagoda that was engraved in a Bodhisattva Image Mirror (Fig. 4). Also the possibility that there was the Odaruki brought from Southern Song is shown in the buildings drawn in the Ajipdo Daeryeon (Fig. 5).
Also from the excavated sites, it is supposed that the Odaruki were using during the Goryeo era. First of all, there is a possibility that the technique of ancient Odaruki was transmitted until the Goryeo era. Some of major temple of Baekje continued to exist until the Goryeo era. It seems that Odaruki was used in Geumdang in the West Courtyard of Mireuksa during the Baekje era, and then deep eaves were also made in the Goryeo era (Fig. 6). In other words, there is a high possibility that Odaruki were continued to be used even during the Goryeo era. In addition, during the Goryeo era, it was found that Geumdang of Jeonglimsa was rebuilt, and Geumdang and wooden pagoda of Wangheungsa were also rebuilt. These temples are famous temple in Baekje, and there is a high possibility that the Odaruki was used.
Next, in Goryeo era there is a possibility that technique of the Odaruki has been newly introduced from China. In the Goryeo royal palace, Hoigyeongjeon (Fig. 7) had deep eaves and it seems that Odaruki was used in this building. This building was built before the invasion of Yuan. Therefore the Odaruki of this building is considered to be Odaruki introduced from Northern Song, Liao, and Jin. On the other hand, the buildings of the West area such as Gyeongnyeongjeon had not deep eaves and it seems that Odaruki was not used. These Western area buildings are built after the Yuan architecture introduced into Goryeo.
These buildings that Odaruki was used were mainly built in the early period of the Goryeo era. Then it seems that they were disappeared by the end of the Goryeo era. It is believed that the technique of the Odaruki was almost lost as a result of the destruction by the invasion of Yuan in the late Goryeo era and the great influence of Yuan architecture in the period of Yuan rule.
