The central image is a monochromatic architectural study, rendered in fine black lines and stippling on a light background. It depicts a multi-story stone building designed as a paradoxical structure, most notably featuring a rectangular, continuous staircase on its roof. Small, identically dressed figures are seen marching in two perpetual lines—one climbing upwards and one descending—along the outer edges of the stairs, creating an impossible cycle of movement that never reaches a beginning or end.
Compositionally, the structure is presented from a high-angle, isometric perspective. The building is designed with classical elements, including arched doorways, tiled roofs, and small towers, all rendered with meticulous attention to shadow and texture. The layout is compact and dense, with complex levels and interlocking staircases that defy Euclidean geometry. A few solitary figures are positioned on lower landings or balconies, providing a sense of scale and further emphasizing the eerie, quiet stillness of the scene.
The artwork is done in the style of a traditional ink or pencil lithograph. The colour palette is entirely grayscale, relying on cross-hatching and dot-shading to define the contours of the masonry and the depth of the alcoves. The lighting is neutral and even, casting subtle shadows that highlight the textures of the stone walls and tiled surfaces without creating dramatic contrast, which keeps the focus squarely on the impossible geometry of the architecture.
