‘This one is good’: Recipes, Testing and Lay Practitioners in Early German Print

By Tillmann Taape

Having recently finished my doctoral thesis on the printed works of Hieronymus Brunschwig, which have previously featured on the Recipes Blog (here and here), I am delighted to contribute to this series of posts on testing and trying (for an overview, see our re-posted summary of the Testing Drugs and Trying Cures conference). What better opportunity to share how it all came together, and reflect on the role of recipes and testing in the narrative.

Hieronymus Brunschwig (c.1450–c.1530), a surgeon and apothecary from Strasbourg, wrote the first printed books on surgery and distillation. In my thesis, Hieronymus Brunschwig and the Making of Vernacular Medical Knowledge in Early German Print, I read these uncommonly practical and technical books alongside records from the Strasbourg archives, about the craft guilds and medical practice. This allows us to make sense of Brunschwig’s practical vernacular medicine in relation to local intellectual trends, different forms of healing, the local milieu of guilds and artisans, and early German print culture.

Brunschwig’s first book was the Cirurgia of 1497, the first surgical manual in print. This, of course, was an opportunity to codify and re-define surgery. Brunschwig revives the medieval tradition of what Michael McVaugh has termed rational surgery (i.e. a learned as well as a practical art), to educate trainee surgeons and to present their discipline as a respectable and useful trade. Emphasising the need for skilled hands as well as a working knowledge of the human body, Brunschwig defends surgery on two fronts: against learned physicians’ rhetoric of superiority, and against other craftsmen’s deep-seated anxieties about occupations which were in contact with sick and dead bodies.

The later books on distillation, published in 1500 and 1512, open up to a wider readership, including not only medical artisans such as surgeons or apothecaries, but also the ‘common man’ – a middling social layer of literate citizens, householders and other lay practitioners. This new kind of medical reader, as I have discussed in a previous post and elsewhere, is emblematised in the figure of the ‘striped layman’ which appears in numerous woodcut illustrations throughout Brunschwig’s works.

Many of the recipes and instructions in the distillation books are adjusted for this type of reader. They start from scratch and are rich in technical details which are not found elsewhere in print or, to my knowledge, in manuscript. Although Brunschwig engages with complex ideas about the nature of matter and its manipulation, such as John of Rupescissa’s notion of a ‘quintessence’ in all things, he re-works them into manageable, pedestrian remedies. Rather than pursuing Rupescissa’s heavenly panacea, Brunschwig uses distillation to produce a type of middle-class quintessences: although earth-bound and imperfect, they were reliable and effective remedies in the hands of laypeople.

One overarching theme of my thesis is the artisan’s approach to understanding and manipulating nature. For a craftsman with no Latin, Brunschwig mined a surprising amount of knowledge from texts. But more importantly, I argue, he knew things through direct physical engagement with bodies, materials and technical processes. His books are full of instructions to probe wounds, check temperature by touch, inspect colour changes in the alembic, and smell or taste distilled remedies. His expertise was located as much in the body and its senses as in books.

Nonetheless, writing was a powerful tool for recording and communicating practical insights. From cautionary tales of exploding alembics to heroic accounts of successful cures, Brunschwig emphasises his own experience as a source of knowledge. The German term he uses for this type of knowledge, erfarung, is related to fahren, meaning ‘to travel’. In the early sixteenth century, it denoted a way of experiencing the world through one’s own senses, by moving through it or simply being in it in an active, attentive manner. Erfarung was compared, often unfavourably, to spiritual contemplation and introspection. Over time, however, doctors and students of nature such as Paracelsus came to see personal erfarung as the necessary labour of insight rather than a sinful distraction. The Book of Nature, they insisted, should be read with one’s feet. Brunschwig’s emphasis on his own and others’ erfarung was thus part of a larger vernacular culture of experiential knowledge, as well as learned debates about experientia which have often been the focus of historical accounts of a medical empiricism developing in the early modern period.

Recipes played a major part in Brunschwig’s codification of experiential medical knowledge. Some, as I have shown in a previous post, were presented in Latin pharmaceutical jargon likely unknown to laypeople. These recipes were closed to readers, who were meant to copy them out on a piece of paper and hand them to an apothecary who would manufacture the remedy according to his art and his experience. Although the great majority of recipes are in German, some of these are also presented as tried and tested, by Brunschwig himself or others, and do not call for ‘tweaking’ on the part of readers.

Other recipes, however, give alternative ingredients or leave the exact composition up to the practitioner’s judgment. Many recipes come without the author’s seal of approval, and their sheer number makes it seem unlikely that Brunschwig could have tested each one. Such ‘open’ recipes leave room for improvisation and testing. The ongoing work of erfarung runs on into readers’ own practice, and often spills out into the margins of Brunschwig’s printed books. In many surviving copies, early modern healers from different walks of life marked recipes with a magisterial probatum est, or a simple vernacular note such as ‘this one is good’.

In some of the earliest medical works in print, Brunschwig addresses a readership of lay healers and ‘common men’ which would come to represent a significant portion of the early German print market. Through his use of recipes embedded within a culture of erfarung, he involved his vernacular readers in a continued effort of empirical trying and testing.

Pursuing the themes of recipes and artisanal knowledge, I am delighted to be joining the Making and Knowing Project at Columbia University this summer, and look forward to sharing our work on making, testing, and trying, which has previously featured on this blog.

 

‘Thus it prevails against its time’: distillation and cycles of nature in early modern pharmacy

By Tillmann Taape

In past centuries, devoid of freezers and heated greenhouses, the seasons affected medicines as well as foodstuffs. In addition to pickled vegetables and stored grain, early modern people worried about their provisions of healing plants and animal substances. These, too, had their season: many herbs were considered most powerful when picked in May, and ‘May dew’ collected from fragrant meadows at this time of year was said to have many healing properties. In his Destillierbücher (distillation manuals), published in the early sixteenth century, the Strasbourg surgeon-apothecary Hieronymus Brunschwig addresses the challenges which arise in pharmacy from nature’s cyclical changes. He explains that most preparations of fresh medicinal herbs are ‘unkeepable’. For example, ‘if you pound herbs, roots or other substances and squeeze the juice from it, then it becomes unpleasant, does not last, […] and soon putrid corruption ensues’.[1] Even with dried materia medica and compound drugs, their medicinal virtues faded over time.

Brunschwig knew this all too well from personal experience. As an apothecary running his own shop near the fish market, maintaining a stock of efficacious remedies was his chief responsibility and expertise. The issue of pharmaceutical provisioning was taken very seriously by Strasbourg’s magistrates. Twice a year, they would send round a committee of medical experts to all apothecary shops, to ensure that no perished goods were stocked, and to throw away any that had gone off.

Brunschwig’s understanding of the material world was shaped by his experience as a pharmacist and shopkeeper, but also by the cosmology and medical theory of his day. While the heavenly spheres were characterised by material perfection and changelessness, all matter on earth was made up of the four elements (air, water,fire, earth) and subject to their constant permutations. They were doomed to endless cycles of generation, change, and decay. Material stability was only possible where the elements were in perfect balance, ‘as you can see in May when it is neither too dry nor too humid, neither too warm nor too cold’.[2]

Brunschwig’s seasonal simile is revealing: a perfect balance of elements is just as rare and fleeting as those precious few balmy weeks in May. As well as pointing to the instability of all earthly matter, the language of seasons and their cold, hot, dry or moist qualities was associated with early modern ideas about the stages of human life. Youth, health, reproduction, decline and death were analogous with the annual cycle of flourishing and decay in nature – a relationship which is richly illustrated in a set of anonymous seventeenth-century engravings (see here for an interactive digital reproduction). The idea of changing seasons was emblematic of an early modern view of the material world which was characterised by instability. Human bodies fluctuated with the shifting balance of their humours, and the very substances which could be used to cure the resulting ailments were themselves fleeting and, in Brunschwig’s words, ‘unkeepable’.

Faced with such difficulties, Brunschwig and others turned to a branch of knowledge with a longstanding commitment to imitating and manipulating natural processes underlying the transformations of matter: alchemy. In particular, Brunschwig describes distillation as a powerful artisanal technique to ‘keep the unkeepable’.[3] Distillation was the art of separation, and in the case of medicinal simples, Brunschwig claimed, their ‘soul’ or healing virtue could be separated from their ‘body’, that is to say the material dross made up of the problematic four elements. Thus liberated, the healing ‘spirit’ of a plant in the form of a distilled water could be bottled and neatly stored on Brunschwig’s alphabetically ordered shelf, where they would keep well beyond their harvest season, for up to three years. Later Destillierbücher echo the idea that one can ‘keep these waters over the year’ as a major selling point of distilled remedies.[4]

While distillation in theory had the power to produce pure and incorruptible ‘quintessences’, this was far too laborious for everyday pharmaceutical practice. Brunschwig wrote for an audience of ‘common men’ as well as artisan colleagues, and most of the distilled remedies he discusses are much more pedestrian. They still have some of the elemental qualities of the original herb, and are ultimately perishable. Compared to ‘unkeepable’ plant juice, however, their decay is slower and more predictable. Brunschwig confidently charts the decline and change in a water’s healing powers over the years, and even gives instructions for ‘recharging’ them. A water can be saved by infusing it with fresh herbs and distilling it once more – thus, Brunschwig reassures his readers, a distilled remedy can ‘prevail against its time’ for another year.[5]

In the early modern world of matter, the seasons symbolised cycles of change and decay which spelled trouble for healers and makers of medicines. In some of the earliest vernacular works on pharmacy, Brunschwig describes distillation as a powerful tool for defying the material corruption of seasonal changes.

The Fruits of Summer in the Dead of Winter

Molly Taylor-Poleskey

In the seventeenth century, life ebbed and flowed with the seasons. In my research into the court household of Berlin, I noted seasonal shifts in livery, lighting, bedtimes, and, of course, recipes. Even with these seasonal adaptations, however, early modern Europeans sought to overcome seasonal growing constraints. One occupation primarily concerned with defying the seasonality of food was that of the court confectioner. It was his (and his wife’s) job to preserve the delicate summer fruits for wealthy Europeans to enjoy even in the depths of winter.

Nicolas de Bonnefons described the rewards of this play with the seasons in his 1654 Les Delices de la campagne, which was translated into English and German and even republished by a Berlin court physician, Johann Sigismund Elsholtz. Bonnefons raptured:

There is nothing which doth more agreeably concern the senses, than in the depth of Winter to behold the fruits so fair, and so good, yea, better than when you first did gather them; and that then, when the trees seem to be dead, and have lost all their Verdure, and the rigour of the cold to have so dispoil’d your garden of all that imbellished it, that it appears rather a desart [sic] than a paradise of delicacies; then it is, I say, that you will taste your fruit with infinite more Gust and contentment, than in the summer it self, when their great abundance and variety rather cloy you than become agreeable. For this reason therefore it is, that we will essay to teach you the most expedite, and certain means how to conserve them all the winter, even so long, as till the new shall incite you to quite the old.[1]

A view into the confectioner’s kitchen in The French gardiner, 1691,

Considering Bonnefons emphatic endorsement of summer fruits in winter, it is perhaps not surprising that confectioners were highly valued in Europe. The moist and cold properties of fresh fruit generally made it a nutritional no-no, according to Galenic principles of diet. However, candied fruits were considered medicinal and the position of court confectioner often fell under the office of the apothecary, not the kitchen.[2] In the Renaissance, it was common to seal the stomach at the end of a rich meal with either fresh or preserved fruits and fruit at a meal was emblematic of the wealth and refinement of the host.[3] By the eighteenth century, the task of the confectioner to create elaborate sugar sculptures for the table was so ingrained that one encyclopedist claimed they belonged to the artist class and prospects had to apprentice themselves to a city confectioner for six years until they had mastered their art.[4] 

Georg Flegel (1566–1638), Still life with cookies and confections (including dried cherries).

The importance of the confectioner is apparent at the court at Berlin in the seventeenth century. The household archives contain a frantic exchange from 1647 between the Great Elector Friedrich Wilhelm (1620-1688) and his counselors about finding a replacement for the deceased confectioner, Johann Schenke, whose wife did not want to carry on the job. It being early summer (Jun 27), the councilors expressed the pressing need to fill the vacancy because “now is the best time for juices and other garden fruits to be preserved.”[5] Friedrich Wilhelm ordered them to install the Prussian confectioner, Johann Tiegel, in the position. He wrote that although they would eventually draw up a contract for him, Tiegel should get started immediately collecting the fruit from the gardens and bringing them to the elector’s tables with the appropriate confections.[6]

When it was finally written, the court confectioner’s employment contract specified the supplies he would receive to carry out his charge: 700 Reichsthaler (in addition to his 80 Reichstaler salary), 960 eggs, as much flour and fruit as needed (from the gardens and from in-kind taxes), 1000 citrons, 1000 bitter oranges, as well as a supply of wood, coal and candles.[7] Occasionally, the confectioner did not get the necessary supplies, which hindered his ability to preserve fruits and was costly for the court. In 1657, Friedrich Wilhelm ordered that Tiegel surely be supplied with apples, cherries, and Black Corinths (Johannisbeere in German) in order to avoid the great expense of having to buy confections from outside of the palace, which had been necessary the previous year.[8]

Cherries were the first ripe fruits of the summer. The sandy soil of Brandenburg was well-suited to growing cherries and in 1656, there were eight varieties of cherries cataloged in the palace garden of Berlin.[9] Dr. Elsholtz wrote that cherries were ripe in June and July and described their consumption: “one eats cherries either fresh or cooked into a soup, or dried, or preserved with sugar. Some make cherry water or a syrup.”[10] Here is a translation of one such cherry recipe reprinted by Elsholtz from Bonnefons:

One makes the cherry syrup from the good, ripe cherry juice, which you press through a hair or linen cloth. For every quart of this juice, add a pound of sugar, boil that to a thick syrup. To clarify this syrup, let it run through a distillation sack.”[11]

Elsholtz’s descriptions also correspond with the menus and food receipts from the Brandenburg-Prussian household archive, which frequently list the ordering or consumption of dried cherries and cherry sauce (Kirschmus), in particular.

In some popular food literature today, there’s nostalgia for a time when humans adhered more closely to the foods nature provided each season. Even prior to industrialization, however, people clearly prized the rarity of a taste of an off-season food. What the archival record reveals, though, is that early modern Europeans of all orders were still hyper aware of what foods were available when and were careful about timing the work of preservation accordingly.

An Early Modern DIY Guide to Making Paper

By Gabriella Szalay

After about half an hour of working it over everything was already so small and delicate that I could scoop, or rather make fine sheets out of it. These sheets allowed themselves to be neatly pressed on to felt, removed from the same and hung up. After they had dried, I was able to size and burnish them[1]

Penned by the Regensburg pastor and naturalist Jacob Christian Schäffer (1718-1790), these words provide a succinct description of the paper making process in the early modern period. They teach us that select raw materials were first turned into a pulp by fermenting them, and then stamping them with wooden hammers operated by a mill or beating them with the metal blades of a Hollander beater. They also tell us that this pulp was then formed into sheets using a mould. These sheets were in turn transferred onto felt blankets in order to soak up the water that helped facilitate stamping and beating. After this they were hung up to dry in a well-ventilated area. Paper intended for printing or writing was then covered with a thin layer of sizing, which typically consisted of animal glue, so that it could better retain ink. Finally, it was rubbed with a flat, hard tool until it achieved a clean finish.

What Schäffer’s text does not tell us that the paper that concerned him was in many ways atypical. It was not made from the macerated linen (i.e. flax) or hemp rags that had served as the material of choice among European paper makers since the thirteenth century.

Rather, as he revealed in a subsequent passage, “it was for me an extremely pleasurable sight, to once again have produced such fine paper from wasps’ nests!”[2]

A complete description of Schäffer’s attempts to make paper from wasps’ nests and other ‘exotic’ materials appears in Versuche und Muster ohne alle Lumpen oder doch noch mit einem geringen Zusatze derselben Papier zu machen (1765). The first of six volumes published by Schäffer on what I call paper trials, it begins with an account of how for generations men of learning had been experimenting with material substitutes for making paper.[3] Their goal, Schäffer argued, was to put an end to the cyclical relationship between waning supplies of linen rags and waxing costs of fine, white writing paper. As an avid participant in the Republic of Letters and as an author and publisher of natural history texts it is not surprising that he was sympathetic to their concerns. Nor that his interest in paper trials was piqued by his fellow entomologist, René-Antoine Ferchault de Réaumur, (1683-1757), who following his close study of American and European paper wasps suggested that it should be possible to make paper from a wide range of botanical specimens, including trees.[4]

Schäffer’s first paper trial, conducted in 1764, examined the possibilities of making paper from the wool-like seeds of black poplar trees. He was disappointed by the initial results, noting how the corresponding sample lacked the rigidity (Steife) and density (Festigkeit) of paper made from linen rags. Nevertheless, he decided to go forward with more trials and had a miniature Stamper built to his specifications and set up in his own house so that he could supervise the paper making process directly. He also hired a couple of journeymen (Gesellen) to help him carry out the more than eighty paper trials on over fifty different kinds of materials that would occupy his attention over the next seven years.

Among the many things that make Schäffer’s paper trials worth further study are how well they are documented and how eagerly they were reproduced by other men of learning. Each volume of Schäffer’s text is filled with entries describing the physical properties and/ or origins of the material under investigation, followed by recipes for turning that material into paper. The entry dedicated to pine cones (Tannenzapfen), for example, begins by identifying them as the fruit (Frucht) or seed-cases (Saamenbehältnisse) of coniferous trees. It then notes that because of their ligneous quality they need to be soaked in water for one week before they can be turned into pulp. Schäffer even tweaked his own recipe, recalling how when the pine cones proved to still be too hard: “I placed them into a lime pit for twenty-four hours, allowed them to be stamped again, and then washed them and stamped them until they were small, delicate and rag-like.”[5]

The precision with which he addressed variables like time, combined with his decision to include samples from each experiment alongside the text turned Schäffer’s books into veritable “how-to-manuals.” Within a year of their publication, men of learning across Europe were installing miniature Stampers in their homes and making paper from Schäffer’s recipes with the help of artisan assistants. Some, like Gerhard Anton Senger (1754-1822), even tried to convince commercial paper mills and government bodies that they should do away with paper made from linen rags, which often had to be imported from foreign suppliers. Instead one should learn to make use of locally available resources, such as the green algae (Conferva) that filled the lakes and streams of Senger’s native Prussia and provided the topic and the material support for his Die älteste Urkunde der Papierfabrikation. Although paper made from Conferva had an unsightly greenish hue, Schäffer noted in his recipe that if left out in the sun, it would eventually assume the pristine, white color that made paper from linen rags so economically and socially desirable.
