Masterpiece of the week

The Painter and his Pug 1745 by William Hogarth 1697-1764 Self-Portrait The Painter and his Pug 1745 William Hogarth 1697-1764 Purchased 1824 http://www.tate.org.uk/art/work/N00112 — **William Hogarth – The Painter and his Pug (1745)** Photograph: Tate

An oval self-portrait of Hogarth is propped on leather-bound volumes of the works of his favourite authors: Milton, Shakespeare and Swift. The palette in front of them is inscribed and illustrated with his philosophic idea of The Line of Beauty, which is serpentine, not straight, according to Hogarth – an idea that puts him at the heart of the European Rococo movement. But his pug dog brings such highfalutin speculations down to earth. Hogarth’s own face mirrors the dog’s ordinariness and toughness. Beauty is not only serpentine, it comes out fighting.
• Tate Britain, London
