Miris, Frans Jansz van the Elder. Portrait of a young man Hermitage ~ part 08

The picture has something of this: people, portrait, woman, wear, girl, music, room, dress, musician, indoors, model, sit, performance, furniture, light, singer.
Perhaps it’s a painting of a man in a black outfit holding a piece of cloth in one hand and a book in the other hand, with a castle in the background.
