Architecture has very often been a representation of the cosmos, not only because with its known laws it relates directly to the scale of the universe and bestows geometries and configurations on the shape of space, but also because it keeps the starry sky beneath a ceiling, or inside a sphere. Since architecture is involved with space it is the ideal art with which to build worlds: from Egyptian temples to medieval chapels, from gardens as symbolic references to Eden, to mazes on a complex stone floor.
