A tightly constructed geometric composition, this work presents an intricate lattice of interlocking forms that shift and recede across the picture plane, creating a mesmerizing sense of optical depth. Siena's precise hand-painted execution in gouache on board reveals the tension between mechanical regularity and subtle human variation, as alternating coffers generate a rhythmic push and pull throughout the surface. The rich, matte quality of the gouache amplifies the work's hypnotic intensity, inviting prolonged visual engagement with its dense, rule-based system.
