This is an etching titled “Hearth-Stones” by John Thomas Smith, first published on April 30, 1816. Notice the careful line work that gives each stone block a solid texture; the heat glows across the central hearth. To the left you can see a small basket of bread and, to its right, a child’s hat resting beside a farm animal peeking from the side. Smith was an early‑nineteenth‑century draughtsman and antiquary, noted for his clear lines and attention to everyday detail.
