Although Orion has a few lines in both Homeric poems and in the "Works and Days", most of the stories about him are recorded in incidental allusions and in fairly obscure later writings. No great poet standardized the legend. The ancient sources for Orion's legend are mostly notes in the margins of ancient poets (scholia) or compilations by later scholars, the equivalent of modern reference works or encyclopedias; even the legend from Hesiod's "Astronomy" survives only in one such compilation. In several cases, including the summary of the "Astronomy", although the surviving work bears the name of a famous scholar, such as Apollodorus of Athens, Eratosthenes, or Gaius Julius Hyginus, what survives is either an ancient forgery or an abridgement of the original compilation by a later writer of dubious competence; editors of these texts suggest that they may have borne the names of great scholars because they were abridgments, or even pupil's notes, based on the works of the scholars.
