His Masterpiece, sometimes translated as “The Work” or “The Masterpiece,” is Zola’s 14th entry in his Rougon-Macquart series of novels. In it we see Claude Lantier, a painter with obvious talent, struggle to leave a revolutionary mark on the art world of 19th-century Paris. The novel deftly explores the themes of genius, poverty, purity in art, art as an beaurocratic institution, obsession, and madness.
