In painting, a pentimento is a vestige of an earlier version of the work, faintly revealed just beneath the surface. The painter may adjust the composition as they work, painting over the original, however—whether intentionally or not—a piece of the original is still visible. There are pentimenti everywhere in the environment around you. You just have to look for them.
