Hesiod ( HEE-see-əd or HEH-see-əd; Ancient Greek: Ἡσίοδος Hēsíodos; fl. c. 700 BC) was an ancient Greek poet generally thought to have been active between 750 and 650 BC, around the same time as Homer. Several of Hesiod's works have survived in their entirety. Among these are Theogony, which tells the origins of the gods, their lineages, and the events that led to Zeus's rise to power, and Works and Days, a poem that describes the five Ages of Man, offers advice and wisdom, and includes myths such as Pandora's box.
