Ji-Yong’s Poetry has been discussed a lot but there is still room for reconsideration in his early poets. This thesis studies newly the image of “water” which is the important characteristic of his poems. First, one of “water” images, “sea” which the poet was the most concerned about is investigated. “Sea” means continuous arrivals of primary and new waves, leading to the new world with risk, which implies that poet’s concern about the sea is finally his pursuit of brandnew space or world in the colonial reality and its poetical imagination. Next, solid glass functions as a different form of water which is fluid and changeful, and in his works glass is a poetic object that can be changed frequently any time in the state of solid or liquid, which produces plentiful poetic images.
