Spatialism is an artistic movement that emerged in the mid-20th century, primarily associated with the works of Italian artist Lucio Fontana. It emphasizes the importance of space in art, moving beyond traditional two-dimensional representations. Spatialists often explore the interaction between the artwork and its environment, inviting viewers to consider the physical space around the piece. The movement is characterized by the use of unconventional materials and techniques, such as slashing or puncturing canvases, to create a sense of depth and dimension. Spatialism challenges the boundaries of art, encouraging a more immersive experience that engages the viewer's perception of space and form.
