So zooming out, we humans have a habit of going into phases of mass destruction, generally self imposed to some extent or another. This handy list shows all the wars over time. Wars are actually the norm for humans, but every now and then something big comes along. I am interested in the Black Death, which devastated Europe. The opening of Boccaccio’s Decameron describes Florence in the grips of the Plague. It is as beyond imagination as the Somme, Hiroshima, or the Holocaust. I mean, you quite literally can’t put yourself there and imagine what it was like. For those in the midst of the Plague it must have felt like the end of the world.
