Answer:
Overlapping is when one part of a shape or form is placed in front of another, Foreshortening is a technique that make a form appear to move back in space. In Mantegna's piece, The Lamentation over the Dead Christ, he used overlapping to provide the depth to the room, and to show the image of Christ on top of the bed. By using foreshortening, the artist was able to make the body of Christ lay horizontal, and therefore receding into the background.

Mantegna created great depth using these techniques.
