Tripartite stained glass window 

Theo van Doesburg, a key figure in the De Stijl art movement, created this abstract stained glass window. The work features the distinct geometric forms and primary colors (red, blue, yellow) that are characteristic of De Stijl. Van Doesburg's artistic vision aimed to express universal harmony through simple, geometric compositions, creating a sense of order and balance in this three-part window. This artwork is a prime example of abstract art and is considered a significant contribution to the history of stained glass.
