History, Seen in Streams
An interactive World Histomap turns four thousand years of history into continuous streams of civilizations, peoples, events, and lifelines.
Field notes
The project adapts John B. Sparks’s 1931 five-foot chart, preserving its two-scale reading experience: a broad historical sweep alongside dense local detail. Its stated method treats civilizations, populations, movements, species, and ideas as streams that may persist, divide, merge, or end. The homepage also presents proposed formats, including a Pacific-centered history and an unbounded population map designed to show demographic expansion and shocks such as the Black Death.
