The Terrain Gallery opened in New York under the direction of painter Dorothy Koppelman, pairing its first exhibition, "Intersection '55," with the publication of Eli Siegel's aesthetic questions under the title "Is Beauty the Making One of Opposites?" The gallery was unusual in treating an exhibition space as a forum for a theory of art: Aesthetic Realism and Siegel's idea that reality's opposites are made one in successful works. Its early program brought contemporary painting, sculpture, graphics, photography, poetry, and public discussion into the same intellectual setting. Later accounts connect the gallery with artists including Chaim Koppelman, Ad Reinhardt, Larry Rivers, Roy Lichtenstein, Andre Kertesz, Mark di Suvero, and Elaine de Kooning, making its founding a distinctive episode in postwar New York's alternative-gallery culture.
It created a long-running artist-run forum where exhibitions were explicitly organized around aesthetic philosophy.
