A triptych is a painting made in three sections that fit together. It can also be three relief carved panels.
Cubism
Jackson Pollock was most associated with the Abstract Expressionism movement. This movement emphasized spontaneous, automatic, or subconscious creation, and Pollock's signature drip painting technique exemplified these ideals. His work focused on the physical act of painting, transforming the canvas into an arena for action and experimentation. Pollock's contributions helped redefine the boundaries of art in the mid-20th century.
Ansel Adams is primarily associated with the 20th-century art movement known as Modernism, particularly within the realm of photography. He was a key figure in the straight photography movement, which emphasized clarity, detail, and composition. His work is also closely linked to the broader environmental and conservation movements, reflecting a deep appreciation for nature. Adams' iconic black-and-white landscape photographs played a significant role in shaping the perception of American wilderness.

It seems there might be a misunderstanding, as I don't have access to the previous question or the specific art and literary movement you are referring to. If you provide the name of the movement and the individuals associated with it, I can help identify which person was not a writer linked to that movement.
