The history of art is almost three times longer than that of writing, and the relationship between the two types of expression can be seen in the earliest forms of writing, such as Egyptian hieroglyphics. However, very few people treat art as a system of communication which is historically linked with language. If more people were to take this view they would find that their approach to art would change. Man is used to the fact that there are languages which he does not at first understand and which must be learned, but because art is primarily visual he expects that he should get the message immediately and is apt to be affronted if he doesn't.
