The term Golden Age (Greek: χρύσεον γένοςchryseon genos) comes from Greek mythology and legend and refers to the first in a sequence of four or five (or more) Ages of Man, in which the Golden Age is first, followed in sequence, by the Silver, Bronze, Heroic, and then the present (Iron), which is a period of decline, sometimes followed by the Leaden Age. By definition, one is never in the Golden Age.
By extension "Golden Age" denotes a period of primordial peace, , stability, and prosperity. During this age peace and harmony prevailed, people did not have to work to feed themselves, for the earth provided food in abundance. They lived to a very old age with a youthful appearance, eventually dying peacefully, with spirits living on as "guardians". Plato in Cratylus (397 e) recounts the golden race of humans who came first. He clarifies that Hesiod did not mean literally made of gold, but good and noble.
There are analogous concepts in the religious and philosophical traditions of the South Asian subcontinent. For example, the Vedic or ancient Hindu culture saw history as cyclical, composed of yugas with alternating Dark and Golden Ages. The Kali yuga (Iron Age), Dwapara yuga (Bronze Age), Treta yuga (Silver Age) and Satya yuga (Golden Age) correspond to the four Greek ages. Similar beliefs occur in the ancient Middle East and throughout the ancient world, as well.
In classical Greek mythology the Golden Age was presided over by the leading Titan Cronus. In some version of the myth Astraea also ruled. She lived with men until the end of the Silver Age, but in the Bronze Age, when men became violent and greedy, fled to the stars, where she appears as the constellation Virgo, holding the scales of Justice, or Libra.
