The Histomap: 4,000 Years of World History in One Graphic

Check out this epic visualization of how the power of different civilizations has changed over time, from the ancient Egyptians to the domination of the Romans and later the British Empire. This image isn’t quite big enough to make all of the writing legible, but you still should be able to see the size of Empires. You can see VERY detailed and interactive version at The David Rumsey Map Collection.
