Pittoni Giovanni Battista (Venice 1687-1767) – Sacrifice of Polyxena (128x95 cm) ca1734 J. Paul Getty Museum

The picture has something of this: people, group, veil, wear, woman, man, lithograph, Renaissance, many, god, kneeling, position, saint.
Perhaps it’s a painting of a group of people standing in front of a statue with a dog in the foreground and a crowd of people in the background.
