Teniers, David the Younger. Portrait of Ghent, Bishop Anthony Trista and his brother. Capuchin Friars Eugene Hermitage ~ part 11

The picture has something of this: people, man, saint, elderly, church, god, priest, prayer, cross, monk, holy, chapel, baby, book.
Perhaps it’s a painting of a man sitting in a chair in front of a bookshelf with a book in his lap and a statue in the background.
