Answer the following question in 3-4 complete sentences. The above piece is a lithograph by M.C. Escher. How has Escher used the concept of space effectively?

Answer:

Escher uses the reflective sphere to show a complete interior space in a curved, distorted perspective. The spherical surface makes the library, seated man, and surrounding room appear to wrap around the ball, creating a strong sense of depth. The large hand in the foreground contrasts with the smaller reflected figure and room, emphasizing scale and the relationship between the viewer and the reflected space. This makes the viewer feel as if they are looking into the scene from outside it.
