That staircase lives in my mind and is a great inspiration, I also have a large photo of it framed on the wall. The story told at the Esherick museum was that the design grew from Esherick's sculptures but 13 years later I came across a design of staircase that was sufficiently similar that I can hardly imagine that Esherick was not aware of it. This one dates from 1522-30 France and is in the Victoria and Albert Museum. It has been in their possession since 1909 but I have never seen it before, whether it has been in store or hidden in a gallery I did not visit I do not know but it is superbly presented in the new medieval galleries and I think is probably my favourite object in the world.
As with Eshericks stair the beauty is in the detail of the execution. The coarse but highly skilled toolmarks, the mark of a master craftsman. working at speed.
And just for fun to see what folk think this video is what brought the staircase to mind today, it only appears in the background behind a modern architect designed tea house. I like the tea house and find it though provoking but can't help questioning the build quality and thinking that the textures are an imitation of the workmanship that I love and will not last.
