This piece by the 19th century English painter William Henry Hunt — known primarily for his watercolors of still life — is tremendously satisfying just as a drawing. The touches of watercolor carry it to somewhere between drawing and painting.
The Rembrandtesque pen lines, slightly wavering but solidly controlled, unerringly define the space, and the washes give it soliditiy and light. This is essentially done in two colors.
Look at how sure Hunt is of his values as he defines the vaulted ceiling, wooden structures, and multiple areas of relative darkness and illumination.
