The artwork “Untitled (for Leo Castelli)” was created by Donald Judd in 1977. It is part of the minimalist art movement and falls within the genre of sculpture.
The artwork consists of a series of large, geometric rectangular structures made from concrete. These structures are aligned in a row outdoors, each displaying a hollow interior. The simplicity and industrial materiality of the pieces reflect the minimalist aesthetic, emphasizing clean lines, precise forms, and the inherent beauty of the raw materials. The repetition of the forms and the interplay of light and shadow within each rectangular unit contribute to the overall impact of the artwork.
