Jacob van Campen – Double Portrait of Constantijn Huygens (1596-1687) and Suzanna van Baerle (1599-1637) Mauritshuis

The picture has something of this: people, wear, portrait, two, woman, jacket, girl, outerwear, lid, facial expression, dress, necklace, model, jewelry, veil, music, musician.
Perhaps it’s a painting of two people sitting next to each other, one holding a book and the other looking at a piece of paper with writing on it.
