Altoon Sultan (1948) is an American artist and author who specializes in rural landscapes painted in egg tempera. Her works are in the collections of the Metropolitan Museum of Art, the Museum of Fine Arts, Boston, and the Yale University Art Gallery. She has received two grants from the National Endowment for the Arts. She received her BFA in 1969 after studying painting at Brooklyn College, and her MFA in 1971, also at Brooklyn College, where she studied with Philip Pearlstein and Lois Dodd. She also attended Skowhegan School of Painting and Sculpture.
Altoon Sultan maintains a popular blog, Studio and Garden, in which she posts nature photographs of her home in Groton, Vermont, her land and garden, her thoughts about her art-making, and reviews and photographs of exhibitions she frequently visits in New York City and elsewhere. Sultan is known for her dedication to materials and color, often valuing the two over a deeper meaning to her pieces. She is also known for rejecting the large scale that minimalist art often takes, instead favoring a smaller, more intimate scale.
