Albrecht Dürer was a Renaissance painter and printmaker from Germany. During the Renaissance, artists figured out how to create the illusion of three-dimensional space on a flat surface. In his 1498 Self-Portrait With Gloves, right, Dürer introduces three layers of space. The subject sits in the first layer, just inside the frame, or the foreground. The second, in the background, recedes through the window on the right. Trees, meadows, hills, and sky are visible through this window, indicating a vast landscape lies beyond. The third layer is unexpected. The subject leans on a ledge and looks out, almost as if looking through a second window into the gallery where the painting hangs. He seems to be inviting the viewer to interact with the art.
