The Brass Butterfly is a lesser-known 1958 play by Nobel laureate William Golding, best known for his novel Lord of the Flies. It is a three-act comedy, often described as a philosophical farce, set in an unspecified ancient Roman or Greek seaside town. The plot centers on an elderly inventor, Phanocles, who arrives at the court of a superstitious and pragmatic Roman magistrate with a series of revolutionary inventions: the steam engine, gunpowder, and the printing press.
The play explores Golding’s signature themes of human nature, progress, and the corruption of innocence. It satirizes both the resistance to change from the entrenched powers (the Emperor and his court) and the naïve idealism of the inventor who believes his creations will bring only peace and prosperity. The central metaphor of the “brass butterfly”—a delicate, beautiful, but ultimately lifeless and mechanized object—questions the true cost of technological advancement and whether human folly will inevitably twist progress toward destruction. While not as famous as his novels, the play is a witty and sharp examination of the clash between innovation and tradition, and the perennial flaws in humanity that doom both.
