Inside the church of Santi Apostoli in Florence, behind a grate, there are three flint stones.
Every year, at Easter, those stones light the fire that sets off the Scoppio del Carro.
Tradition links them to the First Crusade and a Florentine knight. But when a historian went to check, the story turned out to be more complicated — and more interesting — than anyone expected.
In the video, I'll tell you what he found. And I'll leave you with a question: what does Pazzino de' Pazzi have to do with the Battle of Montaperti?
I went to Santi Apostoli to see them. The church is a stone's throw from Ponte Vecchio and almost no one walks in. The stones sit there, in a case, with barely any explanation. Three pieces of flint holding up a thousand-year-old ritual.
If you want to know what Montaperti has to do with it, drop it in the comments.
Save this for your next walk through Florence — and go see them.
