Six Ages of The World

The Six Ages of the World or sex aetates mundi (also, Seven Ages of the World) is a Christian historical periodization first written about by Saint Augustine circa 400 AD. It is based upon Christian religious events, from the creation of Adam to the events of Revelation. The six ages of history, with each age (Latin: aetas) lasting approximately 1,000 years, were widely believed and in use throughout the Middle Ages, and until the Enlightenment, the writing of history was mostly the filling out of all or some part of this outline.

The outline accounts for Seven Ages, just as there are seven days of the week, with the Seventh Age being eternal rest after the Final Judgement and End Times, just as the seventh day of the week is reserved for rest. It was normally called the Six Ages of the World because they were the ages of the world, of history, while the Seventh Age was not of this world or was the World to Come and lasting forever.
