Various ancient peoples, such as the Egyptians, Mayans and Chinese developed interesting maps of the constellations and useful calendars.
Observatories were built in different parts of the world and many data were obtained, taking into account that they started from scratch. But there is not much information about the famous people of ancient astronomy, or the data we know is very inaccurate.
Therefore, we begin with the ancient Greeks. In general, the sages of ancient Greece believed that celestial movements could be explained by the hypothesis that the Earth rotates on its axis once every 24 hours and that together with the other planets it revolves around the Sun. This theory, known As a geocentric system, it remained unchanged for 2,000 years.
Greek astronomy was transmitted by the Roman Empire and also towards the East to the Syrians, Indians and Arabs. Arab astronomers compiled new catalogs of stars in the 9th and 10th centuries and developed tables of the planetary movement.
In the fifteenth century the basic assumptions of the central position and the immobility of the Earth began to be questioned.
This chapter presents the biographies of famous people from this era, when the Earth was the center of the Universe.
