Vintage oil painting: an arched stone entryway opening into a shadowed alley, rendered in rich earth tones with confident, controlled shading. The composition pulls the eye inward through the arch and into the dark.
Architectural studies are the sleeper category in European painting. They rarely command what landscapes do, and they are often better pictures, because an artist working on stone and shadow has nowhere to hide. Hang this where there is a real light source nearby and the depth does the rest.
