Anne-Louis Girodet de Roucy-Trioson – Portrait of Benoît-Agnès Trioson, known as Ruehaus or Ruoz (1790?1804). Previously known as Romainville Trioson Part 3 Louvre

The picture has something of this: people, man, seat, two, woman, wear, portrait, music, sitting, musician, Renaissance, recreation, veil, furniture, indoors, side view.
Perhaps it’s a painting of a man leaning against a wall with his hand on his head and a violin in his other hand and a note.
