 This ambivalence appears to underlie his presentation of human history in "Works and Days", where he depicts a golden period when life was easy and good, followed by a steady decline in behaviour and happiness through the silver, bronze, and Iron Ages – except that he inserts a heroic age between the last two, representing its warlike men as better than their bronze predecessors.He seems in this case to be catering to two different world-views, one epic and aristocratic, the other unsympathetic to the heroic traditions of the aristocracy.The "Theogony" is commonly considered Hesiod's earliest work.
