Its original name was Mathematike Syntaxis (“The Mathematical Arrangement”); Almagest arose as an Arabic corruption of the Greek word for greatest (megiste). Babylonian astronomers had developed arithmetical techniques for calculating astronomical phenomena; Greek astronomers such as Hipparchus had produced geometric models for calculating celestial motions. In a later book, the Planetary Hypotheses, Ptolemy explained how to transform his geometrical models into three-dimensional spheres or partial spheres. Ptolemy wrote the Syntaxis as a textbook of mathematical astronomy. It was translated into Arabic about 827 and then from Arabic to Latin in the last half of the 12th century.
