This work shows Mary Dickinson Riddle, Cassatt’s mother’s first cousin, presiding at tea, a daily ritual among upper-middle-class women on both sides of the Atlantic. Mrs. Riddle’s hand rests on the handle of a teapot, part of a gilded blue-and-white Canton porcelain service that her daughter had presented to the artist’s family. Painted in response to the gift, the portrait demonstrates Cassatt’s mastery of Impressionism in its sketch-like finish, the casual handling of anatomy, and the sitter’s indifference to the viewer. As Mrs. Riddle’s daughter disliked the portrait, Cassatt kept it until Louisine Havemeyer persuaded her to give it to The Metropolitan Museum of Art.
