Last week Friday (you can click on 'previous', above to the right if you would like to view it again) I posted a picture showing part of the Shepherd's Field terrain of the RC Franciscan monks. The Sanctuary is a building on the terrain, that commemorates the angels' appearance to the shepherds, to announce the birth of Jesus.
Inside the Sanctuary, there are three altars, each located in a 'cave'. The 'cave' is like a bay window with a cupola. Behind each altar on this rounded wall, is a painting of what is described in Luke, with relation to the shepherds at the time that Jesus was born. Annunciation, devotion (the visit to the manger) and celebration. The paintings have this strong 3D feel to it, which I believe is due to the shape of the wall, that was so painted. Part of the 3D feel is the result of the technique used by the artist. In this picture, the light that shines down from the angel, really looks as if it is in front of the stars. Then one gets the idea that the angel is floating in the air. Unfortunately, a photograph cannot show that illusion. But I thought it is brilliantly done.
The picture behind this altar is the one about the annunciation.
