Fourth, Fifth, Sixth (and Seventh?) Ages

[Arvegil145]

How about I calculate the average temporal distance between 'parent - child' in regards to (ordinary) Men all over the legendarium? Maybe I can come up with an 'average Mannish Tolkien generation'?

[William Cloud Hicklin]

I'm not sure that when it comes to 1960's writings we can dumbly apply a "latest prevails" rule as if it were legislation. What we have instead is Tolkien thinking with the pen, jotting down ideas whichj he might or might not stick with- and as the years wore on increasingly fuzzed by failing memory.

[James the Just]

The year 10,961 BC seems to come up a lot in many an ancient chronology. Here's one.

The author shows that Atlantis did not vanish “in one terrible day and night” but survived in a variety of different forms well into the historical era. He reveals how the first Atlantean civilization lasted from 432,000 to 33,335 BC, the second one from 21,142 to 10,961 BC, and the third Atlantis civilization--the one celebrated by Plato--collapsed in 9600 BC, after the Younger Dryas cataclysm.

This seems related to René Guénon's date for the Fall of Atlantis. It was somehow worked out to occur 7200 years (144 × 50) before 3,761 BC.

Or even to scientific ideas.

The Younger Dryas (YD, Greenland Stadial GS-1) was a period in Earth's geologic history that occurred circa 12,900 to 11,700 years Before Present (BP).
