Berthold Schwarz

← Encyclopedia

Berthold Schwarz — “Black Berthold,” Latinized as Berthold Niger and in later accounts furnished with the lay name Constantin Anklitzen — is the German friar-alchemist whom Europe long named as the inventor of gunpowder and the firearm. The tradition fixes him at Freiburg im Breisgau, somewhere in the long fourteenth century, bent over the furnaces of an alchemical workshop until a sealed vessel burst and gave him the cannon. Freiburg believed the story firmly enough to carve him in sandstone in the 1850s and stand him in a public square with a mortar and pestle in his hands. The difficulty is that the documentary record holds no man for the statue to portray.

The byname before the man

What survives first, and most stably, is not a biography but a name with an adjective attached, and the adjective carries the whole weight of the legend. Berthold is an ordinary religious name; Schwarz — black — is the part that asks to be read. Three explanations have circulated since the legend took written form, and the tradition has never chosen among them. The plainest reads Schwarz as a family name, an inherited surname like any other. A second reads it descriptively: the black of a friar’s habit, or the soot of a trade conducted over fire and charcoal, the working alchemist’s permanent stain. The third, and the one the legend cannot quite suppress, reads it as a confession — ars nigra, the black art, the art of the alchemist as the medieval moralist classed it. Under that reading the name is an indictment folded into a label, and it binds the most consequential weapon of the age to the most suspect of the medieval sciences before any episode of the life has even been told. The Latinizing form Niger travels the same ambiguity intact; the lay name Constantin Anklitzen, surfacing only in later retellings, is a still later attempt to supply the man with the civil identity the byname never required.

The order is no steadier than the name. Most versions make Berthold a Franciscan; a minority make him a Dominican; the difference matters to anyone who wants to ground him in a real chapter-house, and it goes unresolved because no chapter-house ever recorded him. The 1913 Catholic Encyclopedia, working from the received tradition, places his birth at Freiburg in the first half of the thirteenth century — a full century before the dates other tellings assign to his discovery.

The legend as it settled

The narrative core is an origin-accident, told with the economy of folklore. The friar is at work over the furnaces, grinding or heating a mixture of saltpeter, sulfur, and charcoal. The mixture takes fire in a closed vessel; the lid — in some versions the heavy stone of a mortar — is flung across the room. From that single violent fact Berthold reasons backward to the principle of the gun: a charge confined, ignited, and made to drive a projectile down a barrel. Some tellings carry him further and credit him with casting the first European bronze cannon, so that the same man invents both the powder and the engine that fires it. The accident is the legend’s argument in miniature — it makes the firearm a discovery rather than a transmission, a thing stumbled upon in a German cloister rather than carried west along a trade road.

The Freiburg monument is the legend’s most durable form. Unveiled in the 1850s and sculpted by Josef Aloys Knittel, the yellow sandstone shows the friar robed and holding the tools of his alleged discovery, and its inscription commemorates the five-hundredth anniversary of the invention, fixing it only by implication in the mid-1350s. That anniversary reckoning is itself a choice among many, and the choice has the look of a city settling an argument it had no documents to settle.

What the dates already give away

Before any modern verdict is reached, the chronology undoes itself. Set the surviving dates side by side and they do not converge on a life. The Catholic Encyclopedia tradition has him born around the first half of the 1200s. Encyclopaedia Britannica, following another strand, makes him a fourteenth-century figure who discovered gunpowder about 1313, and adds — on the authority of still other sources — that he was a cathedral canon at Konstanz around 1300 and a teacher at the University of Paris in the 1330s. The Freiburg monument, marking the five-hundredth anniversary of the invention, points to the mid-1350s. Franz Helm, the sixteenth- century gunnery author who gave the legend much of its circumstantial detail, put the discovery at 1380 and had Berthold executed in 1388 for the very art he had invented. A man cannot be born in the early thirteenth century and make his discovery in 1380; the spread across roughly a century and a half is not the ordinary uncertainty of an obscure life but the signature of a name to which incompatible stories were attached by hands that never compared notes.

Scholarship’s cut

What the documentary record establishes runs against the tale at almost every point, and the three registers — what can be dated, what is contested, and what the tradition told about itself — pull cleanly apart.

The first cut is the silence. No contemporary document names Berthold Schwarz. The earliest written trace appears only around 1410, in an anonymous manual of pyrotechnics surviving in fifteenth-century copies, which credits the accidental discovery of gunpowder to a Master Berthold — an alchemist and master of arts — and gives no time, no place, no order, no byname. The epithet “the Black” is not in this first witness at all; the Latin niger attaches to his name only in later copies of the Feuerwerkbuch tradition, and it is Franz Helm, writing in Landshut in the 1520s and 1530s, who supplies the dates, the execution, and the texture of a biography. The town records of Ghent, sometimes invoked as documentary support, consist of entries whose authenticity is itself in doubt. The figure, in short, grows visibly across the sources: thin and anonymous in 1410, named and circumstantial only a century later, and monumental only in the nineteenth.

The second cut is the chemistry’s own history. Gunpowder is Chinese, worked out by Tang-dynasty alchemists of the ninth century who were seeking not a weapon but an elixir, and named in the early Taoist formularies as huoyao, fire-medicine, before any military use was found for it. The knowledge traveled west across the Mongol expansion and the trade roads, reaching the Islamic world and the Latin West late in the thirteenth century; saltpeter arrived under the name “Chinese snow.” By the time of any plausible Berthold the formula was already set down in Europe. It appears in the writings associated with Roger Bacon — the Epistola de secretis operibus artis et naturae and the Opus Maius of 1267 — where saltpeter and sulfur are named openly and the third constituent, charcoal, is hidden under a transposed-letter cipher. The recipe was thus in Latin hands a generation or more before the friar of Freiburg could have struck his spark. (The name “Bacon” here means the thirteenth-century Franciscan, not the later Englishman of the same family name.)

The third cut is the verdict of those who looked hardest. J. R. Partington’s A History of Greek Fire and Gunpowder (1960) — still the standard work, reissued by Johns Hopkins with an introduction by Bert S. Hall — examined the evidence and treated Berthold as a purely legendary figure, a personification rather than a person. A minority position has held out: Franz Maria Feldhaus argued in 1910 that the early-fifteenth-century reports of a “Master Berthold,” surfacing only a generation after the death they imply, deserve to be weighed as genuine testimony rather than dismissed. The contest is real and remains attributed to its parties, but the weight of historiography has settled on the legendary reading: a name onto which a diffuse, foreign, gradually arriving technology was gathered and given a single inventor, a single accident, and a single face.

The shape the legend filled

The figure repays attention less for what he did than for what the legend needed him to be, and that need has its own datable history. Late-medieval and Renaissance Europe wanted an author for gunpowder and reached for the alchemist — the man bent over fire and salts, coaxing transformation out of matter — as the natural maker of a substance that was itself a kind of transmutation, an inert powder become flame and force. Berthold belongs to the same imaginative country as the practitioners of alchemy and the Latin tradition of medieval alchemy who were credited, equally without foundation, with poisons, elixirs, and homunculi: figures in whom the Middle Ages and the natural philosophy of the Renaissance deposited their hopes and fears about the manipulation of nature. The same gathering instinct made Paracelsus and the Paracelsian physicians, the alchemist Cornelius Agrippa, Kenelm Digby with his wound-healing powder, and Johann Konrad Dippel with his animal-oil elixir into bearers of more than they ever made, and that traced every secret art back through Hermes Trismegistus to a single mythic source. Berthold is the war-engine’s entry in that ledger.

There is a later layer still. In the nineteenth century, and most insistently in the German lands as unification advanced, Berthold was lifted from cautionary legend into a figure of national pride — the German monk who gave Europe the gun, a homegrown answer to the embarrassing fact of a Chinese original. The 1850s sandstone monument belongs to that moment. The friar who began as the black art’s confession ended as a city’s and a nation’s claim of precedence, the same name doing opposite work in different centuries.

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.

Sources and scholarship

The indispensable study is J. R. Partington, A History of Greek Fire and Gunpowder (Cambridge: W. Heffer & Sons, 1960; reprinted Baltimore: Johns Hopkins University Press, 1999, with an introduction by Bert S. Hall), which assembled the textual evidence for the European arrival of the powder and reduced Berthold to a personification — the founding modern verdict, still unsuperseded. For the tradition as received before the modern critique, the 1913 Catholic Encyclopedia article on Berthold Schwarz, hosted in the public domain at Wikisource, preserves the Franciscan-Freiburg form of the legend and the threefold reading of Schwarz. The summary in Encyclopaedia Britannica collates the competing dates (the c.1313 discovery, the Konstanz canonry, the Paris teaching) and notes that the only documentary support is the dubious Ghent material. For the chain of attestation — the anonymous pyrotechnic manual of c.1410, Felix Hemmerlin’s De nobilitate et rusticitate dialogus of c.1450, Franz Helm’s sixteenth-century elaboration, and Feldhaus’s 1910 minority defense of historicity — the consolidated account at Wikipedia gathers the references with their sources. On the genuine origin against which the legend is measured, Joseph Needham and colleagues, Science and Civilisation in China, Vol. 5, Part 7: Military Technology: The Gunpowder Epic (Cambridge University Press, 1986) is the standard treatment of the Chinese invention and its westward transmission; the Roger Bacon formula is set out in Lynn Thorndike, A History of Magic and Experimental Science (Vol. II, New York: Columbia University Press, 1923).
