In the Greek Golden Age men lived like the gods under the rule of Kronos; they never suffered the ills of old age, nor lost their strength; they feasted continually, and enjoyed peace and security. The whole world prospered. When this race passed away they became beneficent spirits who watched over mankind and distributed riches. In the Silver Age mankind were inferior; children were reared up for a century, and died soon afterwards; sacrifice and worship was neglected. In the end Zeus, son of Kronos, destroyed the Silver Race. In the Bronze Age mankind sprang from the ash. They were endowed with great strength, and worked in bronze and had bronze houses: iron was unknown. But Bronze Age men were takers of life, and at length Black Death removed them all to Hades. Zeus created the fourth race, which was represented by the semi-divine heroes of a former generation; when they fell in battle on the plain of Troy and elsewhere, Zeus consigned them to the Islands of the Blest, where they were ruled over by Kronos. The fifth Age may originally have been the fourth. As much is suggested by another Hesiodic legend which sets forth that all mankind are descended from two survivors of the Flood at the close of the Bronze Age. In _Le Cycle Mythologique Irlandais et la Mythologie Celtique_, the late Professor D'Arbois de Jubainville has shown that these Ages are also a feature of Celtic (Irish) mythology. Their order, however, differs from those in Greek, but it is of special interest to note that they are arranged in exactly the same colour order as those given in the _Mahábhárata_. The first Celtic Age is that of Partholon, which de Jubainville identified with the Silver Age (white); the second is Nemed's, the Bronze Age (red); the third is the Tuatha de Danann, the Golden Age (yellow); and the fourth is the Age of the dark Milesians, called after their divine ancestor Mile, son of Beli, the god of night and death. The Irish claim descent from the Milesians. Professor D'Arbois de Jubainville considered that the differences between the Irish and Greek versions of the ancient doctrine were due in part to the developments which Irish legend received after the introduction of Christianity. There are, however, he showed, striking affinities. The Tuatha de Danann, for instance, like the “Golden Race” of the Greeks, became invisible, and shared the dominion of the world with men, “sometimes coming to help them, sometimes disputing with them the pleasures of life”. Like the early Christian annalists of Ireland, the Indian Brahmans appear to have utilized the legends which were afloat among the people. Both in the Greek and Celtic (Irish) myths the people of the Silver Age are distinguished for their folly; in the Indian Silver or White Age the people were so perfect and holy that it was not necessary for them to perform religious ceremonies; they simply uttered the mystic word “Om”.[155]
