Masterpiece of the week
Henri Gaudier-Brzeska – Red Stone Dancer (c 1913)
This frenetic image of a totemic dancer is typical of advanced art on the eve of the first world war, when the avant garde across Europe were taking traditional western images apart in a quest for primal essence and energy. Gaudier-Brzeska embodied the international spirit of this modernism: he was born in France, worked in Britain and took the surname of his Polish girlfriend. When the war broke out, he enlisted in the French army and was killed on the western front in 1915.
• Tate Britain, London SW1P.
