The Oude Kerk (Old Church) in Amsterdam has some choir stalls that are very unique for a protestant church. The Oude Kerk was originally a catholic church, but during the reformation was transformed into a protestant one. An "iconoclasm" took place in the Oude Kerk on September 26, 1566 (fn. 1). Remarkably, the images, dating back to 1480, carved into the back of the choir stalls survived.
You'll be surprised that some of the same things you say today have been being said over and over again for the past 527 years.
This first image represents, "Money doesn't fall out of my arse." Your current expression is probably something like, "Money doesn't grow on trees."
This one represents two people living under one roof. It means to say that we tend to gather people around us who think like we do.
This one is "Sail when the wind allows." It means anything is easier when you have good help (or community).
This one is "Money is not worth anything in death." Your current expression is probably something more like, "You can't take it with you."
This one is "You can't yawn wider than an oven door." It means, don't try the impossible.
This one is, "Don't beat your head against a brick wall."
This one shows a man who can't decide between two chairs so he is sitting uncomfortably on the floor. Our current version is "Sitting on the fence is really uncomfortable."
