Almost nothing is known about Ptolemys life. The Almagest was not superseded until a century after Copernicus presented his heliocentric theory in the De revolutionibus of 1543. Ptolemy placed the Earth at the centre of his geocentric model. He came to think that the distances between the planets and their movements could make the tones of the instruments and music in general vary. Therefore, Ptolemy wrote a parallel version of his hypothesis of the movement of the planets, in which he used simpler and more accessible language, directed especially to people not trained in mathematics. The only difference is Although they had great errors, they set a precedent for future developments in cartography and earth science. The contributions of Ptolemy were of vital importance in the worldview of the Middle Ages (Biographies and Lives, 2017). What was Ptolemy's model of the universe? Ptolemy greatest contribution to science He formed the geocentric theory. He put the earth in the center of the universe and contended that these elements were below the moon, which was the closest celestial body.
