Golden Age (χρυσή εποχή) (chrysí epokhí), Silver Age, Bronze Age, Heroic Age, and Iron Age are ages of humanity in Greek myths and legends.
During the Golden Age, Cronus ruled. This is a utopia.
The Silver Age was ruled by Zeus, son of Cronus. People lived long then.
Humanity during the Bronze Age was made of ash tree. Their passion was war.
Then came the Heroic Age. Gods once again fought in various wars.
And finally, the Iron Age. It's more like the simple life of people.
Olympic medals come in bronze, silver, and gold for different places. This symbolizes the Age of Man (Γένη των Ανθρώπων).
