In Hans Baldung Grienís The
Groom and the Witch, c.1540, the body of the man lying paralyzed on the
floor, is shown at an odd angle, along an orthogonal. From that angle, his
feet are extra large, thighs large, chest deflated and head too small to see.
This adjustment in the manís body proportions create the illusion of the
backward extension of his body. As mentioned earlier, objects are perceived
as diminishing in size as they are further away, even within a body Ė horse or
human. Even though the body may, as a result, look totally distorted or
inhuman (especially if he stood up and we saw him from another angle), this
again is true to the actual perception of objects in our world. Foreshortening
also gives information as to the location of the artist/viewer. For us to see
him at that angle with those orthogonals in the room, we would need to be
standing near to his feet with our eyes at the level of the horseís butt.
