A mandala creates a world center within the boundaries of its two-dimensional space analogous to that created in three-dimensional space by a shrine. [6] In medieval times some Christians thought of Jerusalem as the center of the world (Latin: umbilicus mundi, Greek: Omphalos), and was so represented in the so-called T and O maps. Byzantine ...
Some late medieval figures noted that the celestial spheres' physical order was inverse to their order on the spiritual plane, where God was at the center and the Earth at the periphery. Near the beginning of the fourteenth century Dante, in the Paradiso of his Divine Comedy, described God as a light at the center of the cosmos. [70]
Ptolemy argued that the Earth was a sphere in the center of the universe, from the simple observation that half the stars were above the horizon and half were below the horizon at any time (stars on rotating stellar sphere), and the assumption that the stars were all at some modest distance from the center of the universe.

Copernicus follows Aristotle to maintain that circular motion ...
A concrete circle at the apex of a rebuilt span of the old Boston Avenue viaduct, between 1st and Archer Streets, in Tulsa, Oklahoma is known as "The Center of the Universe". The spot produces an acoustical anomaly [13] and it is for which the Center of the Universe Festival and Ms. Center of the Universe Pageant are named. [citation needed]
After Shapley and Hubble showed that the Sun is not the center of the universe, cosmology moved on from heliocentrism to galactocentrism, which states that the Milky Way is the center of the universe. [168] Hubble's observations of redshift in light from distant galaxies indicated that the universe was expanding and acentric. [163]
c. 16th century BCE – Mesopotamian cosmology has a flat, circular Earth enclosed in a cosmic ocean. [1]c. 15th–11th century BCE – The Rigveda of Hinduism has some cosmological hymns, particularly in the late book 10, notably the Nasadiya Sukta which describes the origin of the universe, originating from the monistic Hiranyagarbha or "Golden Egg".
A volvelle from a sixteenth-century edition of Sacrobosco's De Sphaera. De sphaera mundi (Latin title meaning On the Sphere of the World, sometimes rendered The Sphere of the Cosmos; the Latin title is also given as Tractatus de sphaera, Textus de sphaera, or simply De sphaera) is a medieval introduction to the basic elements of astronomy written by Johannes de Sacrobosco (John of Holywood) c ...
