Agnes Pelton was a modernist painter renowned for her mystical and symbolic abstractions that deeply explore spirituality and the meditative qualities of nature. Influenced by early modernism and her own visionary experiences, Pelton’s work is characterized by its delicate interplay of light, color, and form.

In the early 1920s, Pelton painted Hayground Windmill, Bridgehampton, capturing the historic windmill that also served as her residence and studio during that period. This work reflects Pelton's deep connection to her surroundings, as she often drew inspiration from the natural and architectural elements of Long Island. The painting exemplifies her transition from representational art to more abstract, spiritual compositions, influenced by the serene environment of the Hayground area.

Pelton’s artwork is included in prominent collections such as the Whitney Museum of American Art, the Phoenix Art Museum, and the Metropolitan Museum of Art, where her contributions continue to influence appreciation for American modernism and visionary art.
