/internal/media/dispatcher/140900/fullO4undated[Marc Adrian]Marc AdrianMounting behind glass, tempera on panel, relief, riffled glass, lead strips, wooden box In the late 1950s, the Austrian avant-gardist Marc Adrian is a pioneer of the expansion of painting and sculpture, incorporating the factors of movement, time, and participation into his art. His work “O4,” for example, looks different depending on your standpoint. It is a reverse glass montage: The artist painted a panel with cubic shapes in the primary colors yellow, red, and blue, plus black and white elements. He then placed the painting in a wooden box and covered it with panes of ribbed glass. The texture and grid-like structure of the glazing make the assemblage’s appearance change as you approach it from different angles. The color fields start moving.Object art© Bildrecht, Wien 2026https://sammlungtest.belvedere.at/objects/34492/rdf
