NW Europe DIED in a short time.
Your posts are becoming more bizarre. You wrote:
“The Dark Ages began with verifiable scientific facts. Tree rings have been examined and they show several years of no growth ~ meaning a very long Fimbul Winter.”
(sigh) The “Dark Ages” is a reference to a time of little learning, culture, commerce, travel, or advancement.
“St. Gildas interviewed people first hand who’d experienced it ~ his companion, King Ad, attested to it elsewhere.”
(sigh) All of which is completely irrelevant for it says nothing in itself about the Dark Ages as commonly understood nor does it even remotely show any evidence of your completely erroneous claim that the Dark Ages lasted until the 14th century.
“NW Europe DIED in a short time.”
No, it didn’t.
