recorded in old literature. Thus the Sim Cheong narrative or novel may have been fictionally invented using source material found in the medieval Korean historical tracts, Samguk sagi and Samguk yusa. Specifically, Hyonyeo Jieun seolhwa (, "Story of Jieun, a Filial Daughter") found in the former and Gwaneumsa yeongi seolhwa (, "Story about the Origin of ") and (居陀知) narratives found in the latter are the candidate source materials, according to the hypothesis by . Hyonyeo Jieun seolhwa tells the story of a girl named Jieun who took care of her mother by selling her body. Gwaneumsa yeongi seolhwa is about Won Hongjang who made an offering to the Buddha for her father and later became an empress. After becoming an empress, she sent a statue of Gwaneum to Korea, and Gwaneum Temple was built in Gokseong to house the statue. The Geotaji narrative (Samguk yusa, Book 2) contains closely similar motifs, such as the sacrifice being thrown into a pond, and the dragon transforming into a flower. According to one analysis (Jung Ha-young 鄭夏英), at the base are three types of narrative or tale-types: tales about regaining eyesight, tales of virgin sacrifice, and heroic tales, with some 17 additional folklore motifs added, such as birth origins and downfall of a blind man.
