I think I would like to have this map of world history:
“Not a map really, but a 5-foot-high chart showing in one glance 4,000 years of human history on a global scale. Thirty years ago I saw this on the wall of someone’s dorm room and it flipped me out then, and every time I’ve seen it since. Its beauty is how Mr. Sparks divies up world power (somewhat crudely) into its main factions graphed in each increment of fifty years since 2000 B.C.E. Different civilizations are color-coded so one can easily trace the flow and ebb of culture over the centuries.”
Unfortunately, it is out of sale – but luckily there’s still a high quality mirror online.
