The purpose of this study is to find out the charateristics of religiousness and epic technique in the vietnamese Wanseo`s Jeangimanlok(傳奇漫錄). Romance makes use of the epic which extends its context to “after death”, The wideness of the epic context tells Romance was written on the basis of religion. To deliver the author`s messages, the Romance deals with the weirdness and surprises, which religious characteristics give, So the Romance deals with not only the stories of usual lives but that of ghosts, life and death, and the other world, which are all connected with religion. Wanseo used the religious characteristics in his Jeangimanlok. He was used to the technique of Romance, was dipped in the religion in the religious circumstances at that time. I analyzed the religious features and the epic technique of Jeangimanlok in two ways. One is the context of the epic genre and the other is epic devices. The context of the epic is widely presented, which tells Wanseo wrote Jeangimanlok on the basis of religious thinking. The weird surroundings is based Jeangimanlok, and the epic context extends to the other world after death. The epic devices are according to the religiousness. There should be something to commute the other world. Just like the religion, Romance was written based on the dualism of this and that world or the-real-world and the-world-to-be. And using devices such as sleeping, dream, and death secures the reasonable. There were religious features in the epical context and devices of Jeangimanlok. The religious features are closely related with the characteristics of the Romance. That means the religiousness became the genre custom of Romance.
