Ancient Europeans wrote about Ages of Man.

There are also many other references to various
types of world ages or Ages of Man in Hopi
(worlds), Mayan (suns) and other cultures of
antiquity. Giorgio de Santillana, the former
professor of the history of science, mentions
approximately thirty ancient cultures that
believed in the concept of a series of ages and
the rise and fall of history, with alternating
Dark and Golden Ages.
More details of these Ages are available in the
Yuga concept of the Hindus. The present age
is known as Kali Yuga (age of darkness).
