Claudius Ptolemy (c. 100 to c. 170 CE) was an Alexandrian mathematician, astronomer, and geographer. His works survived antiquity and the Middle Ages intact, and his theories, particularly on a geocentric model of the universe with planets following orbits within orbits, were hugely influential until they were replaced by the heliocentric model of the

The geocentric model of the solar system is the ancient concept where the Earth is believed to be the center of the universe. In this model, the Sun, Moon, stars, and planets appear to revolve around the Earth. This was commonly known as the Ptolemaic view, named after the Greek philosopher who propounded it in the second century AD.

Geocentrism as a separate religious belief, however, never completely died out. In the United States between 1870 and 1920, for example, various members of the Lutheran Church–Missouri Synod published articles disparaging Copernican astronomy and promoting geocentrism. Howev
