The Five Ages of Man According to Hesiod's Works and Days (see ML pp. 81-83)

1. Golden Age: mortals who live as gods, free from pain, sorrow and trouble

2. Silver Age: where "a child was a child for 100 years"; men were foolish, and committed crimes against each other

3. Bronze Age: men were violent and warlike, and destroyed each other

4. Age of Heroes: men were demigods, but always engaged in war

5. Iron Age: the worst - men are constantly beset by troubles, grow old quickly , and are always opposing one another
