Focus on Interior, after Dinner and discuss the Description.
The painting shows two women seated at a table and a man standing. Camille Doncieux has been positively identified in the gray gown, appearing a year before she and Monet were to be married. It is unclear who the other two people might be. Marie-Louise Adelaide-Eugenie Sisley, the future wife of Alfred Sisley (1839–1899), and Sisley himself are said to possibly appear seated in The Dinner.  However, this becomes less clear in the companion piece of Interior, after Dinner. The man standing near the fireplace mantle could be Monet's friend Frédéric Bazille (1841–1870).
