I’ve always noticed stonecutter markings whenever I travel to Europe and I tend to look for them when I’m looking at some historical building. I saw them in Heidelberg and I found some on my Notre Dame. They kinda cool to find them if you know what you’re looking for. I find it kinda sorta fun to see if I can find them and maybe that’s just weird to me.
I’ve been cutting some of these landscape blocks with modern tools and all that I can say is “Damn!!!! How did they mange to do that so well?” I suppose a lifetime of working with stone is the answer. That and time and patience. I get maybe one stone cut in three just OK by my standards and I know the stone mason masters would have sent my honey back to the quarries if they saw how my cuts came out.
