Hesiod, HEE see uhd or HEHS ee uhd, was a Greek epic poet who probably lived during the 700's B.C. Scholars attribute two major poems, the Theogony and the Works and Days, to Hesiod. The Theogony combines traditional tales and Hesiod's ideas about the creation of the world, the succession of divine rulers, and the genealogy of the Greek gods. It is one of the earliest sources of information about Greek religion. See Mythology.
