I have an open mind on whether this article is loony bin science or some arcane classification of the history of civilisations. History isn't my field. In any event the timeline that pretends to be a graph seems to have come mainly from this source.
Mr H may be pleased to learn that I did give the site more than three minutes. It isn't climate science. Perhaps it is an attempt at fitting human behaviours into some long term cyclical pattern with weather references as allegory only.
