The Ages of Man are the stages of human existence on the Earth according to Greek mythology. The first extant account of the successive ages of humanity comes from the Greek poet Hesiod's Works and Days:
Golden Age – The Golden Age is the only age that falls within the rule of Cronus. Created by the immortals who live on Olympus, these humans were said to live among the gods, and freely mingled with them. Peace and harmony prevailed during this age. Humans did not have to work to feed themselves, for the earth provided food in abundance. They lived to a very old age but with a youthful appearance and eventually died peacefully. Their spirits live on as "guardians".
Silver Age – The Silver Age and every age that follows fall within the rule of Cronus' successor and son, Zeus. Men in the Silver age lived for one hundred years under the dominion of their mothers. They lived only a short time as grown adults, and spent that time in strife with one another. During this Age men refused to worship the gods and Zeus destroyed them for their impiety. After death, humans of this age became "blessed spirits" of the underworld.
Bronze Age – Men of the Bronze Age were hardened and tough, as war was their purpose and passion. Zeus created these humans out of the ash tree. Their armor was forged of bronze, as were their homes, and tools. The men of this Age were undone by their own violent ways and left no named spirits; instead, they dwell in the "dank house of Hades". This Age came to an end with the flood of Deucalion.
Heroic Age – The Heroic Age is the one age that does not correspond with any metal. It is also the only age that improves upon the age it follows. These humans were created from the bones of the earth (stones) through the actions of Deucalion and Pyrrha. In this period men lived with noble demigods and heroes. It was the heroes of this Age who fought at Thebes and Troy. This race of humans died and went to Elysium.
Iron Age – Hesiod finds himself in the Iron Age. During this age humans live an existence of toil and misery. Children dishonor their parents, brother fights with brother and the social contract between guest and host (xenia) is forgotten. During this age might makes right, and bad men use lies to be thought good. At the height of this age, humans no longer feel shame or indignation at wrongdoing; babies will be born with gray hair and the gods will have completely forsaken humanity: "there will be no help against evil."
