Babylonian astronomers had developed arithmetical techniques for calculating astronomical phenomena; Greek astronomers such as Hipparchus had produced geometric models for calculating celestial motions. The Almagest of Claudius Ptolemy is often unfairly disparaged by modern commentators for a number of supposed failings. One of the most powerful creations of Greek science was the mathematical astronomy created by Hipparchus in the second century B.C. Some errors may be due to atmospheric refraction causing stars that are low in the sky to appear higher than where they really are. (At least one translator also introduced errors.
