MUL.APIN is the conventional title given to a Babylonian compendium that deals with many diverse aspects of Babylonian astronomy and astrology.
It is in the tradition of earlier star catalogues, the so-called Three Stars Each lists, but represents an expanded version based on more accurate observation, likely compiled around 1000 BC. The text lists the names of 66 stars and constellations and further gives a number of indications, such as rising, setting and culmination dates, that help to map out the basic structure of the Babylonian star map.
The text is preserved in a 7th-century BC copy on a pair of tablets, named for their incipit, corresponding to the first constellation of the year, "The Plough", identified with Triangulum plus Gamma Andromedae.
