Mary Cassatt was an American painter and print-maker. She lived much of her adult life in France, where she first befriended Edgar Degas and later exhibited among the Impressionists. She often created images of the social and private lives of women, with particular emphasis on the intimate bonds between mothers and children. She often used her family for models. The oil painting by Mary Cassatt entitled "Two Sisters" is a beautiful work done to honor her older sister Lydia. Lydia was about 7 years older than Mary. Mary loved her dearly and used Lydia as a model for several of her paintings. Lydia died of Bright's Disease at a fairly young age. This painting shows the strong bond between Lydia and Mary. It is a tribute to the bond and love between two sisters. In the foreground of the picture is Lydia, seated, with Mary lovingly hugging her sister. If one looks closely at the image, they can tell the difference in the girls ages. Lydia looks much older than Mary and the depth of the brush strokes and the complexions of the paint demonstrate the talent Cassatt had for impressionistic painting.
