Berthold Schwarz

← Encyclopedia

Berthold Schwarz — “Black Berthold,” sometimes Latinized as Berthold Niger and in later accounts given the lay name Constantin Anklitzen — is a legendary German friar and alchemist credited with the European invention of gunpowder and the firearm. The tradition places him in Freiburg im Breisgau in the fourteenth century, and Freiburg honored the story long enough to raise him a monument; whether such a man ever lived is another question entirely.

The legend, as it settled in early-modern retellings, runs that Berthold was a Franciscan (in some versions a Dominican) working over the furnaces of an alchemical laboratory when a mixture of saltpeter, sulfur, and charcoal exploded in a sealed vessel and flung its lid across the room. From that accident he is said to have reasoned his way to the cannon. The byname “Schwarz” — black — is variously explained: as a family name, as the soot of his trade, or, most tellingly, as the ars nigra, the “black art” of the alchemist. That last reading is the legend half-confessing what it is: a story that binds the most consequential weapon of the age to the most suspect of the medieval sciences.

What scholarship establishes cuts against the tale at almost every point. No contemporary document names Berthold Schwarz; the figure surfaces only in sources written long after the events ascribed to him, and the dates assigned to his life vary by decades across them. Gunpowder itself was Chinese in origin and reached the Latin West well before any plausible Berthold could have worked — the formula is set down in Europe by the later thirteenth century, in writings associated with Roger Bacon. Historians of the subject have generally concluded that Berthold Schwarz is a personification rather than a person: a name onto which a diffuse technological inheritance was gathered and given a single inventor, a face, and a founding accident.

The figure is worth attention less for what he did than for what the legend needed him to be. Late-medieval and Renaissance Europe wanted an origin for gunpowder, and it reached for the alchemist — the man bent over fire and salts, coaxing transformation from matter — as the natural author of a substance that seemed itself a kind of transmutation. In that sense Berthold belongs to the same imaginative territory as the alchemists who were later credited, equally without foundation, with poisons, elixirs, and homunculi: figures in whom the period’s hopes and fears about the manipulation of nature took a human shape. He is not the inventor of gunpowder. He is the form the question of its invention took, when the answer was unknown and the suspicion ready to hand.
