＜Dongmyungwang-pyun ＞, written by Lee Kyu-bo, is an outstanding work of epic in Korean literature history, which is widely recognized for its significant historiographical and literary values. A.D. 1193, Lee Kyu-bo published ＜Dongmyungwang-pyun＞ on the basis of the birth mythology of Goguryeo. Despite of the hugh gap of time, around 800 years, the myth is still well-known to contemporary people as a great piece of literary achievement as well as a prominent narrative art which contains the instructive values that have affected Korean people even until these days. In spite of the fact that there actually exist a diversity of analyses on epics and myths, most of them dealt with the deeds of protagonists or heroes focused only on the standpoint of narrative structure, and in addition, the unique characteristics of space within the story and the chronological development have been separately studied with the main narrative, then this approach seems to be unmethodical and unsystematic. Since these analytic measures have exactly been applied to ＜Dongmyungwang-pyun＞ likewise, an integrative and reasonable analysis which can organize all the factors contributing to the text such as spatio-temporal background and the story itself, is obviously required as it originally should be. The narrative of ＜Dongmyungwang-pyun＞ adopts a three-stage structure as a story developmental method, introduction(appearance)-evolvement(encounter, ordeal, conquest)- denouement(achievement). And also, the spatio-temporal settings consist of two-direction phase, vertical movement emerges from among heaven, earth, and netherworld, and the horizontal one transpires through the on-earth sequences. Futhermore, the uniqueness of the story comes from the chronicle specialty of four-generation-descendants, Cheonje(heavenly God)-Haemosu-Jumong-Yuri. In current circumstances that classical literature works have been considered to be the creditable material for culture contents creation and in the situation of them induced the alteration of the originals into a variety of contents in another genre, the signification of ＜Dongmyungwang-pyun＞ is regarded remarkable. So accordingly, consistent and moderate studies on ＜Dongmyungwang-pyun＞ should be highly required in an angle that the story certainly is the distinguished source for culture contents creation.
