This is impressive. 4,000 years of world history have been condensed to fit onto a single map, created by John B. Sparks and printed in 1931 by Rand McNally. The 1,5 metre map was advertised as “clear, vivid and shorn of elabouration”. The Histomap displays four thousand year’s of World history, and with the use of colour empahised “how the power of various ‘peoples’ evolved throughout history”.
