Claudius Ptolemy

Claudius Ptolemy is the man who came to earth after Jesus was born. Whose astronomical research and observations have controlled the movement of astronomy for one and a half thousand years. Ptolemy's Almagest is considered to be the best book in the history of ancient astronomy.
Ptolemy gave the first idea about the earth and the sun.
But it later proved to be wrong. But his idea remained in people's minds for 250 years.
