Today’s work of art is yet another painted by David Teniers the Younger, a Flemish artist born in Antwerp. The painting is a Self-Portrait at an Inn, finished in 1646.
Here’s how one source describes the painting:
David Teniers the Younger is one of the greatest Flemish painters of the 17th century; he specializes in genre scenes, especially indoor ones, in taverns. This is what his self-portrait shows here, like a manifesto; he has depicted himself, with a pitcher in one hand and a glass of beer in the other. One can note the minute description of the place, the restrained range of colour, the attention given to details which become as many still lifes, and the brushstrokes, precise and delicate, yet not effaced.
