Ariadne on Naxos Franz Gerhard Von Kügelgen (1772-1820)

The picture has something of this: nude, people, woman, Renaissance, shirtless, man, two, position, wear, son, sculpture, portrait, barefoot, veil.
Perhaps it’s a painting of a nude woman sitting on a rock with a cloth draped over her body and holding a cloth in her hand, with a mountain in the background.
