A Scene from Undine, engraved by Charles W. Sharpe Daniel Maclise (1806-1870)

The picture has something of this: people, group, reclining, baroque, woman, many, sculpture, man, mammal, invertebrate, god, veil, wear, Renaissance.
Perhaps it’s a painting of a man riding a horse next to a woman on a horse in a wooded area with other men and women in the foreground.
