I am listening to ANCIENT ROMANS by Thomas R Martin. Struck at how closely the fall of western civilization follows the fall of Rome. It is available through Blackstone audio using their Downpour app. How MIGRANTS took over civilization and the outcome is the end of this fascinating book about the rise of Mediterranean civilizations. Not to be missed. https://www.amazon.com/Ancient-Rome-Justinian-Thomas-Martin/dp/0300198310
