Mrs. Edward Deshon Brandegee John Singer Sargent (1856-1925)

The picture has something of this: people, woman, sculpture, god, costume, ancient, statue, dress, wear, fashion, festival, man, spirituality, performance, veil.
Perhaps it’s a painting of a woman in a white dress standing on a balcony with her hands in her pockets and her right hand in her other hand, with a tree in the background.
