What is art? Why do we value images of saints, kings, goddesses, battles, landscapes or cities from eras of history utterly remote from ourselves? This history of art shows how painters, sculptors and architects have expressed the belief-systems of their age; religious, political and aesthetic. From the ancient civilizations of Egypt, Mesopotamia and Greece, to the revolutionary years of the nineteenth and twentieth centuries, the artist has acted as a mirror to the ideals and conflicts of the human mind. He has always started with reality, but has selected and re-shaped that reality to create a parallel world, a world of the imagination.
