This has to do with the Neuschwanstein Castle in Bavaria. The famous one "mad" King Ludwig II caused to be built that's now a major tourist attraction. I visited it perhaps 20 years ago and finally got around to seeing it again in May, this time paying more attention to its murals.
The place is filled with murals, most dealing with German legends that Richard Wagner (who Ludwig patronized) incorporated in his operas. A sense of this is conveyed here on the part of the Neuschwanstein Web site that presents a "tour" of the castle.
My problem? It's that I noticed that one artist who seemed especially good at conveying facial expressions -- something akin to stage actors who act even with their eyes to convey something to the audience. But the castle tour rules strongly state that no photography is permitted, so I couldn't capture images of examples. Worse, the number of images of Neuschanstein murals on the Internet is small, so only one decent example turned up. All of this meaning that it's essentially impossible to convey to you what I found on my tour of the place.
The artist who stagecraft I noticed is August Spieß (1841-1923), a Munich-based painter about whom little can be found other than this. Worse, there are almost no images of his work on the Web other than parts of some of his Neuschwanstein murals or possibly related work.
So the point of this post is to alert readers planning to visit Neuschwanstein to keep their eyes peeled for murals by Spieß in various rooms (they aren't all in Ludwig's bedroom).
