Graphic Design spans the history of humankind from the caves of Lascaux to the dazzling neons of London City. In both this lengthy history and in the relatively recent explosion of visual communication in the 20th and 21st centuries, there is sometimes a blurring distinction and over-lapping of advertising art, graphic design and fine art. After all, they share many of the same elements, theories, principles, practices and languages, and sometimes the same benefactor or client. In advertising art the ultimate objective is the sale of goods and services. In graphic design, "the essence is to give order to information, form to ideas, expression and feeling to artifacts that document human experience."[2] The paintings in the caves of Lascaux around 14,000 BC and the birth of written language in the third or fourth millennium BC are both significant milestones in the history of graphic design and other fields which hold roots to graphic design. The Book of Kells is an early example of graphic design.It is a lavishly decorated hand-written copy of the Gospels of the Christian Bible created by Celtic monks around 800AD.From 1892 to 1896 William Morris' Kelmscott Press published books that are some of the most significant of the graphic design products of the Arts movement, and made a very lucrative business of creating books of great stylistic refinement and selling them to the wealthy for a premium. Morris proved that a market existed for works of graphic design in their own right and helped pioneer the separation of design from production and from fine art.The work of the Kelmscott Press is characterized by its obsession with historical styles.This historicism was, however, important as it amounted to the first significant reaction to the stale state of nineteenth-century graphic design. Morris' work, along with the rest of the Private Press movement, directly influenced Art Nouveau and is indirectly responsible for developments in early twentieth century graphic design in general.
