Sunlight is the oldest source of light energy rising over the Earth each day, and a fundamental natural energy on which humanity has long depended. Moonlight, likewise, does not produce light on its own but appears through the reflection of sunlight. In this sense, all natural light energy ultimately originates from the sun. Today, the sun is gaining renewed attention as a sustainable and environmentally friendly energy source through technologies such as solar power, continuing to have a significant impact on contemporary society and the environment. This work visually explores the origin and continuity of light by drawing inspiration from the symbolic imagery of the sun and moon depicted in Irworobongdo, a royal court painting from the Joseon dynasty of Korea. The form of the piece is derived from the circular shapes of the sun and moon seen in Irworobongdo, emphasizing the fundamental source of natural energy that continuously influences our lives. Rather than reproducing the surfaces of the sun and moon themselves, the work focuses on the light radiating outward from them. Through this approach, the piece visualizes the flow of energy as light expands into space, metaphorically expressing the relationship between humans, the environment, and the primordial energy of nature.
