Previous Episode: Apology and Explanation

On November 1, 1755, All Saints Day, the city of Lisbon, Portugal was hit by a massive earthquake. The shaking lasted more than three-and-a-half minutes. Frightened residents ran out from beneath their crumbling buildings for the open safety of the harbor. But those who lingered too long, were swept out to sea by the tsunami that followed forty minutes later. And then came five days of fire. The earthquake not only shook up the people of Portugal; it had a profound effect on the European Enlightenment.
