This article aims to explain the mythical meaning and functions of Segyeong-Bonpuri by disclosing the identities of Nejindeokcheonghanim and Jeongsoonam. The research examines the structure of the initiation rite to explain the distinctive features of the characters in Segyeong-Bonpuri. The narrative is centered on the initiation rites of Jacheongbi and Jeongsoonam, and appoints Mundoryeong, Nejindeokcheonghanim, and Jumohalmang as the characters who encourage and guide their initiations. Although Nejindeokcheonghanim and Jeongsoonam hold the lowly status of Nobi, they become sacred beings by the former guiding the initiation rites and the latter acquiring their divine status. Their contradictory status can be explained by two reasons: First, the narrative manifests the energetic characteristics of the Nobi in pre-modern society. They are persistent in sustaining their own lives and those of their masters, and often form a bridge between their masters who have limited range of activities and the outer world. Second, the narrative also reflects a mythical perception that nullifies the distinctions between gods and men, men and animals, men and women, high and low, superior and inferior, and noble and humble by assigning sacredness to lowly, worthless characters. As a result, Segyeong-Bonpuri represents how the agricultural gods acquire their divine status in initiation rites and emphasizes the agricultural principle of balance and cooperation among gods, men and animals.
