Hendrik Gerritsz. Pot (Dutch, c. 1585–1657), Portrait of a Woman with a Dog, c. 1635. Oil on wood. Framed: 77 x 67 x 7 cm, Unframed: 41.8 x 32 cm. The Cleveland Museum of Art, Bequest of Dr. Paul J. Vignos Jr. 2011.47.

The unidentified sitter wears rich black fabric and a brown fur stole, a sheer white linen cap covers her head, an elaborate starched ruff rings her neck, her sleeves finish in punto in aria lace, and a prominent gold ring with a jewel appears on her right hand. The composition, weighted heavily to the right, implies a pendant portrait, yet to identified, probably depicting her husband.

The wooden box on the floor would have held a dish of glowing coals: an early space heater!
