What was the tallest building of the ancient world? Or the average life expectancy in medieval Byzantium? Where did scientific writing first emerge? What was the bloodiest ritual human sacrifice ever? We are used to thinking about history in terms of stories.

Radical historians Peter Turchin and Dan Hoyer draw on their own Seshat project - a staggeringly ambitious log of demographic and econometric information for every society that has ever existed - to find the large-scale patterns in Figuring Out the Past. Join them now for a dive into the numbers that reveal the true shape of the past.
