This study lookd upon the structure in Gosangugokga in the aspect of deviant stylistics. The result of this study is as follow;1. There are one symmetrical expression(2) and two deviant expressions(1, 3) that are able to help us understanding the symmetrical structure in the background time of Gosangugokga. 2. As the result to examine the symmetrical expression(2) and two deviant expressions(1, 3), and the other expressions, we understood the sequential/symmetrical structure in the background time of Gosangugokga. The sequential/symmetrical structure is composed by the combination of the climactic structure and the anti-climactic structure and by the combination of the four time(morn, day, evening, night) and the four season(spring, summer, fall, winter). 3. There are one symmetrical expression(2) that is able to help us understanding the symmetrical structure in the background space of Gosangugokga. 4. As the result to examine the symmetrical expressions(1, 2), the deviant expressions(1, 2), and the other expressions, we understood the sequential,symmetrical structure in the background space of Gosangugokga. The symmetrical structure is [mountain and rock(the second unit)―stream( the third unit)―mountain(the fourth unit)―stream(the fifth unit)―symmetrical axis(the sixth unit)―stream(the seventh unit)―mountain(the eighth unit)―stream(the ninth unit)―mountain and rock(the tenth unit)]. 5. There are six symmetrical expression(3-8) and one deviant expression(3) that are able to help us understanding the logical structure of Gosangugokga. 6. As the result to examine the symmetrical expressions(1-8), the deviant expressions(1-3), and the other expressions, we understood two logical structure. One logical structure is the symmetrical structure that is the combination of the climactic structure and the anti-climactic structure in the 2nd-10th units of Gosangugokga. The other logical structure is the symmetrical structure that is [the introduction(the 2nd unit)―the development(the 3rd unit)―the turn(the 4th unit)―the conclusion(the 5th unit)]―symmetrical axis(the sixth unit)―[the introduction(the 7th unit)―the development(the 8nd unit)―the turn(the 9th unit)―the conclusion(the 10th unit)] in Gosangugokga.
