Catasterism
The ''Catasterismi'' or ''Catasterisms'' ( Greek Καταστερισμοί ''Katasterismoi'', "Constellations" or "Placings Among the Stars") is a lost work by Eratosthenes of Cyrene. It was a comprehensive compendium of astral mythology including origin myths of the stars and constellations. Only a summary of the original work survives, called the ''Epitome Catasterismorum'', by an unknown author sometimes referred to as pseudo-Eratosthenes. Summary The ''Epitome'' records the mature and definitive development of a long process: the Hellenes' assimilation of a Mesopotamian zodiac, transmitted through Persian interpreters and translated and harmonized with the known terms of Greek mythology. A fundamental effort in this translation was the application of Greek mythic nomenclature to designate individual stars, both asterisms like the Pleiades and Hyades, and the constellations. In Classical Greece, the "wandering stars" and the gods who directed them were separate entities, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
