Our world view has changed from a flat earth under the dome of heaven to a planet spinning in the universe. We perceived the world as a body, like ours, then as a tree, a pyramid, an altar, and finally as a veil which became a window through which we peered only to discover ourselves on a sphere, a bubble which might burst at any moment. Our changing views are interpreted through iconic images of the remote and more recent past: the Venus of Willendorf, the Pyramids, Stonehenge, the Taj Mahal, the "Scream," Sydney Opera House, and the Guggenheim, Bilbao.
