In the cosmic model, the assertion is that the form of a permanent settlement should be a magical model of the universe and its gods. Such a crystalline city has all of its parts fused into a perfectly ordered whole and change is allowed to happen only in a rhythmically controlled manner. To achieve such form, specific phenomena are included, such as returning, natural items, celestial measurement, fixing location, centeredness, boundary definition, earth images, land geometry, directionality, place consciousness, and numerology. These are acknowledged in creating the city's form by devising methods for finding a good site, making boundaries, subdividing land, determining a center, connecting to celestial forms, fixing coordinates, controlling change, determining social structure, codifying rules, coordinating physics and metaphysics, and reinforcing form through ritual.
Debate surrounds the origin of cities. For example, the spiritual significance in city genesis is argued by Adams, Rykwert, and Mumford against materialist arguments, such as those of Childe, Sjoberg, and Jacobs.
