Compact timeline of global history

Histomap 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.

It has three uses for me: whenever I am reading about some historical event I can instantly see what else was going on in the world at that time (for instance, what was happening in France during the Ming Dynasty). I also get a very intuitive sense of the rises and falls of civilizations, a pattern that no other chart or book has been able to give me. And hanging on the wall, it never fails to elicit gaps of shock when visitors recognize our modern place in the chart. At ten bucks, it’s a bargain education.— KK

Understanding geological and biological time

Correlated History of Earth

The long view. Or rather, views. Geological time and biological time run at such different paces that the two perspectives are not easily brought together. This crisp chart joins them with extraordinary clarity. It lays out the chronologies of continents skittering around the globe, of comet and asteroid impacts, and of life’s increasingly diverse groups of living creatures and how they fit into geological time. And more. Ordinarily, combining such staggering amounts of information would yield mush and muddle. But this exquisitely printed, laminated poster manages to present 4.5 billion years of geology and biology as the unified whole that it is. Like a good map it teaches something at two feet away, or you can get out a magnifying glass and read down for details. — KK

• From the chart’s Web site:
  “Included are plate tectonic maps, mountain building events (orogenies), major volcanic episodes, glacial epochs, all known craters from asteroid and comet impacts, over 100 classic fossil localities from around the world, fossil ranges of plants, invertebrates and vertebrate life forms, and major extinction events as revealed by the fossil record. Also evident on this chart are the “Cambrian explosion” of animal phyla and the juxtaposition of reptiles and mammals across the Cretaceous/Tertiary (K/T) boundary. Hundreds of illustrations add a striking visual dimension to the data.”

5,000 years of history in one square meter

Diagrammatic Chart of World History

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, previously-reviewed 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.— KK
