"Ogamdo", which means map viewed from crow, written by Lee Sang is a Korean modernist poem. Although many scholars have studied this work, they haven`t explained completely contents of it. When Korea was occupied from Japan and was become a colonial country, Lee Sang practiced painting, first, and then wrote his works, that is, novels, poems, and essays. Then he was participated Guinhoi(Nine Members Meeting) with Kim Ki-rim, Jeong Ji-Yong, etc. to talk and discuss a literary topics included the western modernism and others. That time, I think, he recognized Korean traditional myth related to the three legs crow in the old Korean myth. In the old myth the crow has lived in the sun and given the human bing help. When Lee Sang had composed Ogamdo, he used it as symbols to explain the various preassure from Japan in the colonial period. And so I think he was interested in the western modernism related to James Joyce`s mythic narrative included T. S. Eliot, and when wrote works he used this method. Now Lee Sang`s works have been studied till deconstruction theory, and in this sense I think scholars must review Lee Sang`s works by postcolonial theory.
