Diagrammatic Chart of World History over the last 5000 years

“Simply the best overview of the long now I am aware of. Displays with utmost intelligence 50 centuries of civilization, as revealed in the complex rise and fall of ancient powers. Because it is not as linear as the famous Histomap, it is not as handy for quickly locating a fact in time, but its extra dimensions make this diagram the one I keep returning to to grok the past 5,000 years.”
