@Moo @Kes I actually have another take on that. It's not so weird, because I know that European nobility and wealthy were in love with the folding screens. Now, the stone and folding screens I am not sure that's a good combination, but... I googled it and found this on WIKI:
Spread to Europe[edit]

Folding screens were introduced in the
late Middle Ages to Europe.
[1] In the
17th and 18th centuries, many folding screens were being imported from China to Europe.
[1][2][15] Especially the French had a certain admiration and desire for the Chinese folding screens,
[2] along with the rest of Europe,
[1] and they began importing large lacquered folding screens adorned with art.
