Various elements of Hesiod’s poems (cosmogony, theogony, series of proverbial maxims, etc.) originate in Eastern Literature, and this assertion is today accepted by all. The author of this paper thinks that the knowledge of those models could be profitable in order to study how Hesiod has modified and combined them to produce his great poems. He also believes that Hesiod is dependent on Greek poetry inspired on those models and on other ones more properly Greek. But the result of his re-elaboration of the pre-Hesiodic Greek poetry is two poems very new and original regarding their composition and ideas.
