Monticelli, Adolphe Joseph Thomas – Aan het altaar, 1870-1886 Rijksmuseum: part 3

The picture has something of this: texture, abstract, wall, vintage, dirty, people, sooty, wear, dark, decay, background, retro, decoration.
Perhaps it’s a painting of a woman standing in front of a window with sunlight coming through the window and casting a shadow on the window pane behind her.
