I would then posit a heterodyne effect as well..

Two frequencies should exist..
296 years
123 years..

Anyone see a correlation ??

Yeah, the 126 year period is just about as long as any new conquering "empire" lasts before it is overthrown, usually starting with the locals at the center of the empire.

The 296 year beat probably tracks the price of beer at the wholesale level in Western Europe.
