Ptolemy presented his astronomical models in convenient tables which could be used to compute the future or past position of the planets the Almagest also contains a star catalogue which is a version of a catalogue created by Hipparchus Its list of forty-eight constellations is ancestral to the modern system of constellations but unlike the modern system they did not cover the whole sky (only the sky Hipparchus could see) Across Europe the Middle East and North Africa in the Medieval period it was the authoritative text on astronomy with its author becoming an almost mythical figure called Ptolemy King of Alexandria the Almagest was preserved like most of extant Classical Greek science in Arabic manuscripts (hence its familiar name) Because of its reputation it was widely sought and was translated twice into Latin in the 12th century once in Sicily and again in Spain.
