ABSTRACT
Whenever we look at pictorial images we are alluding to features they do not contain. In Chapter Two the principal allusion discussed was that to three- dimensional space: a variety of procedures can be adopted that result in the pictorial image providing a closer approximation to the perception of objects in space, The concern in Chapter Three was with more arbitrary, but no less important, allusions - those to the meanings conveyed by written words. The illustrations presented in this chapter are more closely akin to the literary allusions mentioned in the Introduction. That is, they are visual allusions that can be interpreted in several ways, some of which will be more immediately evident than others.
