Un coprifuoco olandese del 1637 conservato al Rijksmuseum: un oggetto utilizzato per prevenire gli incendi domestici durante la notte ma consentire al fuoco di covare senza fiamma in modo che possa essere riacceso al mattino

That’s pretty smart. As a mildly related anecdote, when I was young I once jumped over a bonfire which was extinguished for more than 30 hours, of course one of my legs ended up right in the middle, and despite wearing sneakers I got seriously burnt. That was some kind of lesson I guess.

It’s from a temporary exhibition at Rijksmuseum in Amsterdam, called Thuis in de 17e eeuw (At home in the 17th century). I really recommend it if you’re visiting Rijksmuseum. The audiotour in English is narrated by Helena Bonham Carter, and it’s delightful.
