This paper is a study of the Adokira section of the Heungbeob(興法) chapter of the Samguk Yusa. This section concerns Ado, who introduced Silla to Buddhism. Previous studies have focused on ascertaining such historical facts as when Buddhism was introduced and who introduced it. However, the section itself is composed of myths and folktales, so before discussing historical facts, we must first examine the text from a literary perspective. Adokira includes quotes from the inscription on the stele of Ado (‘Ado Bonbi‘), which depicts Ado‘s mother Godoryeong as being like the ‘Great Mother‘(Daemo) of the Sungmo myth that had previously been passed down in the Silla and Gaya regions. Ado is also depicted as having the ability to perform miracles, overcoming various crises without any help. The ending of the tale, in which Ado makes and steps into his own grave, is particularly reminiscent of the Buddhist folktale of the Saptaparni Cave. and his grave bears the same characteristics as caves mentioned in the Jataka(stories of the former lives of Buddha). By choosing to die, Ado personally brings about the propagation of Buddhism in Silla as foreseen before the time of Buddha. Moreover, his tale is also significant as the origin myth of a new start through the death of a mythical character. Ilyeon not only quotes the inscription on the stele of Ado, but he also lifts content from the Seokdamsijeon(釋曇始傳) to recreate the early period of the spread of Buddhism in Silla. In this recreation, Ado, the first messenger of Buddhism, first introduces Silla to Buddhism at Heungryunsa(興輪寺), the first Buddhist temple. In Adokira , harmony is achieved between man, space and time, and the section concludes with a literary portrayal of the beginning of the propagation of Silla Buddhism.
