This document discusses different ways that space can be depicted in art. It begins by explaining that space can be flat, like shapes on a flat background, or it can have depth so that the viewer sees into a window. It then provides examples of artworks from various artists from 1913 to 1973 that demonstrate flat space or space with depth. The document further discusses how shapes can be positive or negative, and how space can become a stage for 3D forms. It also notes the possibility of seeing different images within the same space, like bats or angels. The document concludes by providing examples of student works that explore techniques like linear perspective, window light, paintings within paintings, and complex spatial relationships.
