Donald Judd’s Untitled 10-R (1968) and Untitled 9-L (1978) exemplify his use of industrial materials to create precise geometric forms. His emphasis on materiality and structure reflects a dialogue between human-made objects and the natural world, echoing the rhythms and patterns found in nature. The works interact with their environment by responding to light and space, highlighting the relationship between art, landscape, and the viewer’s physical experience.
