Diptych of Martin Van Niewenhove Pic2 Hans Memling (1430-1494)

The picture has something of this: people, indoors, portrait, man, wear, woman, furniture, sit, room, two, side view, door, window, facial expression, wood, elderly.
Perhaps it’s a painting of a man sitting at a table with a book in front of him and a stained glass window in the back of the picture behind him.
