Proportions of Stone_Stack is a minimalist sculpture located in Seoul, South Korea, created by Lee Sisan. The work takes its premise from a simple arithmetic problem. Subtract the total height of the stones from floor to ceiling, and what remains gets divided into eight equal intervals – each occupied by a stainless steel box of identical dimension. The stones, collected from natural contexts, vary in size and carry the irregular memory of their origins. The steel boxes hold none of that. Together, they produce a wall that is simultaneously resolved and restless, a system that enforces order on material that was never meant to submit to it.

Donald Judd is the explicit reference point here, and the comparison is productive. Judd’s stacks achieved their tension through seriality alone – identical units accumulating into a rhythm the eye could follow without interruption. Lee introduces a variable: nature itself, inserted into the gaps. The stones do not simply break the sequence visually. They reassert their own logic within a framework that was designed to contain them. The system accommodates them, but does not absorb them.

This is the core tension Lee has been working through across his practice. He collects stone, wood, and metal from environments both industrial and geological, then places them in deliberate relation to one another. The interest is not in contrast for its own sake but in calibrating exactly how much distance remains between contrasting qualities – and whether that distance can be narrowed or widened through the arrangement of form. Proportions of Stone_Stack makes this inquiry unusually legible. The arithmetic is visible. You can trace the logic and still feel the friction between its two halves.
