I have defined art as the creation or invention of linked and sequential pattern which extends over all aspects of the composed field. This definition builds a strong link between the concepts of art and composition. This is a very procedureal sounding definition. Art is a language and as such must be capable of reflecting this human dialectic. Decorative art is one side of limited possibilities.
Wall paper has limited possibilities.
I must define possibilities in this context. There are two major types of composition. The Greek artists designed by area, an example of which is the golden section. The details of design by area will be discussed in due course. The Renaissance artists designed by inter related lines that spanned and swirled over the surface.
