In this painting, Wine Glass and Boat, Dali uses perspective and depth perception to paint an image that seem surreal. Obviously, no wine glass would be as big as a boat (unless it is a pretty tiny boat or extremely large glass) but Dali makes it appear that the two object are the same size. Lets assume that each object is of normal size. The way at which we are looking at them; the positions in which they are, the perspective and the use of depth, it appears as though they are of equal size. Dali acheives this by using depth. When we look at two objects; one of which is in the distance and large, the other which is very close and small, if we look at them the right way they apppear to be the same size. This has to do with physics and how our perspective and perception of objects can skew what they really are.
