Historians get real­ly ner­vous about pat­terns. That’s chang­ing a bit now. And the truth of it is there’s not much way to avoid the 500‐year cycle. You almost have to work too hard to unsay it, it’s so obvi­ous­ly there in every way. And if you say every 500 years we go through one, then you imme­di­ate­ly say we’re in the 21st cen­tu­ry and baby are we going through one.
