Sweerts, Michael (Flemish, 1618-1664) 2 Flemish painters

The picture has something of this: people, portrait, music, man, stringed instrument, musician, facial hair, guitar, instrument, two, wear, sit, mustache, singer, guitarist, seat, veil.
Perhaps it’s a painting of a man sitting at a desk with a book in his lap and a skull on the ground in front of him and a book.
