Falstaff at Herne’s Oak, from The Merry Wives of Windsor, Act V, Scene v James Stephanoff (1778-1874)

The picture has something of this: people, woman, costume, wear, man, fairy, lid, fantasy, two, saint, veil, son, three, group, brownie, Renaissance.
Perhaps it’s a painting of a man and a woman standing next to each other in front of a tree with an antelope on it’s head.
