-Hesiod- Edith Hamilton, “Mythology”
According to another story, the gods themselves created men. They made first a golden race. These, although mortal, lived like gods without sorrow of the heart, far from toil and pain. The cornland of itself bore fruit abundantly. They were rich also in flocks and beloved of the gods. When the grave covered them they became pure spirits, beneficent, the guardians of mankind.
In this account of the creation the gods seemed bent on experimenting with the various metals, and, oddly enough, proceeding downward from the excellent to the good to the worse and so on. When they had tried gold they went to silver. This second race of silver was very inferior to the first. They had so little intelligence that they could not keep from injuring each other. They too passed away, but, unlike the gold race, their spirits did not live on after them. The next race was of brass. They were terrible men, immensely strong, and such lovers of war and violence that they were completely destroyed by their own hands. This, however, was all to the good, for they were followed by a splendid race of godlike heroes who fought glorious wars and went on great adventures which men have talked and sung of through all the ages since. They departed finally to the isles of the blessed where they live in perfect bliss forever.
The fifth race is that which is now upon the earth: the iron race. They live in evil times and their nature too has much of evil, so that they never have rest from toil and sorrow. As the generations pass, they grow worse; sons are always inferior to their fathers. A time will come when they have grown so wicked that they will worship power; might will be right to them, and reverence for the good will cease to be. At last when no man is angry any more at wrongdoing or feels shame in the presence of the miserable, Zeus will destroy them too. And yet even then something might be done, if only the common people would arise and put down rulers that oppress them.
