Besides calling out the psychiatrists to which the authors refer, I took on the subject to assign that prophetic role to the authors in this eschatological, calamitous, era which they identify with climate change and inhumanity, degradation, incontinence, alienation, &tc. Were you able to listen to the Hayes and Martin lectures (You may find transcript @ Yale; some do along with syllabus), you would apprehend the relevance of that function in that tradition is not predictive power.

What happened to prophet Isiah, prophet Jesus, prophet Luther (HAPPY BIRTHDAY!), prophet Miller? Nevermind.

Consider the relevance of pagan or gentile prophetic traditions to the authors' despair amid "human futilitarianism".

I visited VikingLady years ago, looked around, and haven't been back. It was difficult to avoid as there are few more authoritative references on "humanity" (and wiccan ritual and recipes) beside Smedley Butler and Robert Altmeyer.  

And The Bible.

Little Known Fact: an UID, also a film buff, responded to a comment I posted about The 13th Warrior --much in the way I recommended Last Kingdom to you. You know that story: Muslim ambassador meets crude Vikings in thrall of superstition, dispels mystery. walp, VikingLady keeps an excerpt of ibn whathefu's memoir. That encounter with Rus was reported to be the literary basis of the film plot. Of course, I went in search of the translator and complete text, because that's what I do.

Diversity is the key to economic and political evolution.

Not using symbols for numbers, I don't think there was millennialism as such as in the magic of big, round numbers. Or at least I haven't heard of it.

The Twilight of the Gods on Norse mythology is interesting because it becomes less clear the more one studies it. Has it happened? Is it going to happen? An interpretation I have come across is that what we see is a mix of a cyclic myth with death and re-birth of the world colored by the three year winter 536-539 AD as Fimbulwinter and interpreted through and adopted to a Christian world by Snorre. That could explain the variations and unclear time frame.
