Portrait of a Woman as St. Agnes, Traditionally Identified as Catherine Voss Sir Godfrey Kneller (1646-1723)

The picture has something of this: people, woman, Renaissance, nude, reclining, girl, portrait, baroque, baby, god, Mary, son, veil, indoors, saint.
Perhaps it’s a painting of a woman holding a lamb in a wooded area with a tree in the background and a blue sky in the middle of the painting.
