Miss Walpole, Afterwards the Hon. Mrs. Keppel (one of pair)

The sitter is presented in a blue gown with a black ribbon at the throat, her hair arranged in an updo accented by pearls. Her expression is restrained and her gaze turns away from the viewer, reflecting the conventions of genteel portraiture in mid‑eighteenth‑century England.

Cotes employs a subtle chiaroscuro, using a darkened backdrop to model the face and upper torso and to give the figure a three‑dimensional presence. The handling of oil paint retains a softness associated with Rococo aesthetics while revealing the artist’s skill in rendering fabric and delicate accessories.

Francis Cotes, noted for advancing pastel methods and later a co‑founder of the Royal Academy, painted this piece during his mature period. The portrait, together with its companion, entered the collection of the Clark Art Institute, where it remains part of the museum’s permanent holdings.

The work exemplifies the mid‑1700s English aristocratic portrait tradition, where women of status were depicted in refined attire and modest demeanor. Its Rococo styling aligns with contemporary European tastes, while Cotes’s emphasis on texture and light anticipates later developments in British portraiture.
