The Three-story Stone Pagoda at the Donghwasa-Temple Biroam, the Sarira Jar made of Pagodite, Gilt-bronze Sarira Reliquary, and the stone-built statue of Vairocana which is enshrined as a jujon in Daejeokgwangjeon Hall, which were excavated from within the temple, were art pieces created at the same time the temple of King Minae of Silla dynasty was constructed during the Age of King Gyeongmun of Silla. Therefore, this thesis attempted to shed light on the characteristics and significance of these Buddhist artworks, which can represent the later age of Silla dynasty as original royal pieces, and to simultaneously study the construction system of temples in late Silla from a Buddhist artistic standpoint. The Sarira Jar made of Pagodite, excavated from the Donghwasa Temple Biroam Three-story Stone Pagoda, is notable in that it has the same form as Sarira Reliquary used in neighboring nations during the same time period. Pagodite was considered jade that was tantamount to jewelry at the time. Moreover, the front of the Sarira Jar made of Pagodite was covered in black lacquer and a prayer was elaborately carved as an epitaph would be. These characteristics show that the Sarira Jar made of Pagodite was an original royal piece of the highest class. The Gilt-bronze Sarira Reliquary was made using methods different from those used to make metal reliquaries in prior times, showing technological development. Also, the pedestal and halo of the Buddha Triad Images carved on each side of the Gilt-bronze Sarira Reliquary were expressed as grandeur elements of a new form that could not be found in Silla dynasty at that time. Also, to express the Buddha Triad Images, the back of the metal plate was tapped outward, making it protrude using the repousse technique, and then a line engraving technique, expressing lines using various chisels on the front side, was adequately combined to enhance realism and depth. Such characteristics can only be found in metalwork produced for the Royal Palace. The stone-built statue of Vairocana also embraced a Buddhist statue style that had newly been passed down from China and transformed into Silla dynasty style instead of applying the traditional Unified Silla Period Buddhist statue style. Also, these style characteristics appear in the stone seat of a Buddhist idol in Borisa-temple in Gyeongju and in the jujon at the stone-built statue of Vairocana at the Bulguksa-Temple so while the stone-built statue of Vairocana at the Donghwasa Temple Biroam is not in Gyeongju-city, as it is a Buddhist statue constructed on a national level, it can be considered to be representative of the newest Buddhist statue style. Donghwasa Temple Biroam Buddhist artworks have style characteristics that represent late Silla dynasty because, as recorded on the Sarira Jar made of Pagodite, when the Royal Tomb Buddhist Temple of King Minae of Silla dynasty was constructed, directors were mobilized along with minister s aides dispatched from the nation to supervise Buddhist services. In other words, it is assumed that master craftsmen from the nation were mobilized and they created the Donghwasa Temple Biroam Three-story Stone Pagoda, Sarira Jar made of Pagodite, Gilt-bronze Sarira Reliquary, and stone-built statue of Vairocana.
