Lydia Amanda Brewster Sewell (February 24, 1859 - November 15, 1926) was a 19th-century American painter of portraits and genre scenes.

[2] Lydia Amanda Brewster studied art in the United States and in Paris before marrying her husband, fellow artist Robert Van Vorst Sewell.

He learned to be a sculptor to create wood carvings and sculptures for the house, fashioned after Medieval designs.

[5] The National Academy of Design said that her "artistic tendencies were stimulated by the mountain scenery around her home and before she received any instruction she attained considerable facility in the use of color.

[3][11] Sewell exhibited her work at the Palace of Fine Arts and the Woman's Building at the 1893 World's Columbian Exposition in Chicago, Illinois.

[18] The painting, called an "important" work by The Independent,[19] depicts dancing Greek maidens and children leading a procession of cattle to the sacrifice.

Harper's Weekly commented, "These joyous figures, moving in a leafy glade into which the sunlight filters, are charming in color and rhythmic movement, and as a piece of admirably conceived and executed decorative painting it stands alone in the collection.
