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 mirrored sphere to show an entire room, including the seated man and the surrounding furniture. The curved reflection distorts the room but still creates a strong sense of depth inside the small ball. The hand holding the sphere appears in the foreground, outside the reflected space. By combining these viewpoints, Escher makes the space seem both contained and expansive.
