This work interprets the Sun, Moon and Five Peaks and the Hangungdo in their existential meaning and explores the relationship between the world we experience and our perception of that world, expressed through the appearance of nature. The arch in the work is one of the two basic types of Western stone architecture, but it is also often used in bridges and palaces in Eastern architecture. It combines with the curves of the pillars and roof eaves of Joseon architecture to create our unique traditional formative beauty, one that connects the Joseon objects and Western elements in the work. Universal human perception and philosophy are thus expressed through the fusion of objects. This work consists of two forms. One is to look at an object directly, and the other is to view an object through the shape of a door (window) expressed as an arch. A form of looking. As Heidegger said in his book “Being and Time”, there is a difference between experiencing things directly and indirectly. Through this work, I wanted to simultaneously experience and connect the viewer with the direct experience of looking at an object and the indirect experience of looking through the window.
