‘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.

 

The Ichthyologist’s Garden

By Didi van Trijp  and Robbert Striekwold

On a gloriously sunny day in May we rang the doorbell of ichthyologist Martien van Oijen’s home in Leiden for a rather peculiar project. Even though the original plan had been to carry it out in a laboratory setting, on account of the beautiful weather we all agreed to move the project outside. In his garden, Martien had set up a table on which had been placed an array of equipment for dissection together with some specimens of red seabream that he had bought at the fish market that morning. The reason for all this? The replication of an eighteenth-century recipe for preserving fish skins.

This method was developed by Johan Frederic Gronovius (1690–1762), a physician and botanist based in Leiden. He boasted an extensive cabinet with all sorts of naturalia ordered according to the Linnaean system. In his quest for collecting specimens he developed a method for drying and compressing fish skins that would allow one to glue them to the pages of a book – much like dried plants in a herbarium. He described this method in a letter to Peter Collinson, who read it at a meeting of the Royal Society and had it published in the Philosophical Transactions in 1742.[1] Compared to other ways of preserving fishes Gronovius’ method was quite easy and affordable, as few materials were needed. The only requirements were a pair of scissors, wooden plates, a linen cloth, ‘minikin pins’, and cartridge paper. Thus, according to Gronovius, “in the space of 24 hours, the fish is prepared.”

We set out to replicate Gronovius’ method step by step, carefully documenting each act with photographs and taking extensive notes along the way.[2] The first order of business was to cut the fish open with a pair of scissors, while making sure that the fins were not accidentally destroyed.

Then most of its right half and all of the intestines were removed, which resulted in a rather gruesome sight.

Then we washed the left half and patted it dry with a linen cloth. After spreading the fins with pins, we exposed the half fish to the sun so that it could dry further (in the absence of sun, Gronovius recommended exposing it to the hearth).

We noticed fairly soon that some of the steps were not entirely clear to us. For one, what to do about the impressive swarm of flies that instantly flocked to the carcass once it was laid out to dry?

Most importantly, although Gronovius said the skin could be separated from the flesh “with very little trouble” after the drying step, it took considerable effort to do so. This may have to do with the fact that some of the steps are described in a somewhat ambiguous manner. We interpreted the step telling us the “back-bones are then to be cut asunder” to mean that the backbone should be cut but not removed.

After drying, however, these bones were very hard to remove, so we now think the entire backbone should be discarded before the drying step. Subsequent attempts with new specimens should shed more light on these issues.

The replication of this method is proving to be very insightful by giving us first-hand experience with a pertinent aspect of our respective projects: the preservation of fish specimens so that they could be collected, circulated, stored and classified. Fishes were notoriously difficult to preserve, losing their shapes, colours, textures, and often spoiling despite the collector’s best efforts to prevent these processes. So far, Gronovius’ method has indeed proven to be very quick and remarkably doable, and it appears to preserve the fish in very good shape, although we are not quite done with it yet.

After removing the dried flesh, the skin was placed between paper and left under a press overnight.

The next morning an elegantly flattened half-fish came out that would have done Gronovius proud.

Unfortunately, it did not smell quite as good as it looked. Our next step will be to use the recipe for a particular varnish that has been written up by Gronovius in a letter to one of his correspondents after having received a number of rotting fish skins. If all goes well, this should remedy the stench of the specimen – now safely stored in the freezer awaiting further treatment – and keep it in its current unspoilt state for many decades.

Recipes in the archives of the early Royal Society

By Sietske Fransen

‘What is a recipe?’ was the simple opening question asked by the organizers of the virtual conversation hosted by The Recipes Project. This month-long online discussion has made me look at the archives of the Royal Society with different eyes.

During my weekly visits to the Royal Society Archives in London I am usually searching for anything visual from the period 1660-1710. Once found, the particular page of archival material with something visual on it is added to the Making Visible database. With this database the Making Visible team is creating a research tool through which it will be possible to enter the archives on image level, and ask and answer questions about the usage of images in early modern science. Have a look at our blog in case you are curious to find out more, or follow us on twitter @MVCRASSH. However, while my colleagues and I are looking for images, we also come across many other interesting documents that are currently part of the early archives. Like recipes!

Those of you who have followed the Twitter storm during the #recipesconf might have seen that I have tweeted about recipes in the last few weeks: recipes for the making of pigments and varnish; food recipes (for bread, butter, and bacon); and medical recipes. The discussions on Twitter have made me come up with several questions. And even though there are too many questions to answer in one blog post, I will discuss them briefly, and hope to continue this wonderful conversation with so many colleagues around the globe.

First of all, why did all these recipes make their way into the archives of the Royal Society? When I started working on the Royal Society materials two years ago, I did not expect to find so many recipes for making food and drinks, nor was I expecting the Fellows’ interest in the making of pigments and varnishes. However, it turns out that the Fellows of the Royal Society were very interested in the history of trades, which made them collect recipes from artisans, including many recipes and treatises on things related the making of images, book printing, and engraving techniques.[1]

The food recipes might need to be seen from the perspective of making products in the house, with which men and women can show off their skills to their friends.[2] During my tweet-storm, I showed a set of recipes brought to the Royal Society by John Evelyn about how to make the best French bread. But also bacon, butter, cheese, and cider recipes are part of the collections in the archives.

In the case of the bread recipe we have the name of John Evelyn stuck to it. And it is indeed interesting to know who provided the Fellows of the Royal Society with the information now in the archives. Who were the sources for the recipes? Were they named? Relatively often we find a name on the recipe. Many to the recipes related to the art of picture making have male names on the recipes, such as Jonathan Goddard in the recipes for colours. Between the recipes I found several had a female name on them, such as the butter recipe from Mrs Elizabeth Papworth, and the recipe for a remedy for scurvy by Mrs Bancroft. Is this surprising? Not at all, since regular readers of this blog know very well that recipes were very often collected by women in early modern English households. However, from the perspective of the early history of the Royal Society it is definitely interesting how recipes from women are still part of the archives. Much more research needs to be done on the women around the Royal Society.

There was an interesting discussion about whether or not the description of a tool needed for the performance of the recipe (such as an oven for bread baking) should be treated as a recipe? Or is it even an ingredient? The description of the oven in John Evelyn’s bread recipe almost looked like a recipe inside a recipe, as it was so clearly describing the various things needed to make the oven and made sure it would actually work correctly. And a good working oven was a prerequisite for making the best bread in itself. Also here I am looking forward to a continuing discussion about tools in recipes!

Finally, I would like to quickly answer a question that Elaine Leong raised  about the many underlinings and crossing-out in a recipe for curing rabies. As I suspected the crossings were done in the original document that was brought in to the Royal Society. The recipe was thought important enough to make it into the Royal Society’s Register Book, where we find it again in volume 7. All the crossed out sections that you can see in the image to the left are omitted from the neat version of the recipe in the Register book. Also the information about the effective cure of the His Majesties’ dogs is left out. But instead we do find a short Note Bene, explaining that the plant named in the recipe as “Starr of the Earth” has several Latin and vernacular namens “known among Botanists”, which will make it easier to find this ingredient.

Thanks to the organisers of the #recipesconf for giving me a great excuse to look into recipes in the Royal Society Archives and for all the stimulating conversations online!

Seasonality and the (Re)creation of Early Modern Color Worlds

By Jenny Boulboullé

Color played an important role in the early modern world across a number of areas from arts and crafts to Christian religion to politics to natural history and philosophy. In recent years, scholars have begun to explore how early modern men and women engaged, produced and conceptualized colors within and across color worlds.[1] Just as in early modern culinary and medical recipes, seasonality is a recurrent theme in artisanal recipes. The art of preservation was highly valued for its powers to make flavors and healing properties of foodstuffs, plants and herbs endure well beyond their seasonal availability. In my contribution to the seasonality series I focus on recipes that celebrate the art of color preservation and on the mindful attention to seasons called for in color making recipes. I am particularly interested in the challenges that recipes for making natural dyes and pigments from seasonal products posed to modern historians trying to reconstruct them.

Today the symbolic significance of colors in early modern Europe is perhaps most readily associated with the compellingly colorful medieval and renaissance art works that have survived in sacred spaces and museums.

But in the pre-modern period a deep concern with colors was not limited to the arts: colors were associated with the four humors and close attentiveness to colors was of vital importance to practices of healing in the Hippocritean and Galenic medical tradition.[2] The perception and display of colors was also highly charged with political meanings: colors were a form of symbolic communication and played an important role in consolidating and displaying religious and secular power relations. European courts and courtly events were important sites of “chromatic politics” as contemporary witness accounts and meticulous historical reconstructions of ephemeral, yet splendid and compellingly colorful festive events have shown.[3]

The historical reconstruction of a sixteenth-century dress, originally created for the Augsburg Imperial Diet from 1530, is a particularly compelling example of the politicized use of brightly colored dress made from dyed textiles.[4] The owner of this dress and his contemporaries might have regarded its colors “as related to intrinsic qualities and powers”. Deep scarlet reds were regarded at that time “as carriers of life and heat, while a strong yellow was linked to gold as metal, which had given its powers by the influence of the sun”. Ulinka Rublack notes the challenges encountered during the reconstruction process. The yellow color obtained in their first dying trials “was just not quite vibrant enough” which was detrimental “as faded hues of yellow could have negative associations of weakness and coldness”.[5]

Other sixteenth century recipes for ‘yellows’ from organic sources, demonstrate that making natural dyes of this color depended on local seasonal knowledge. As Marieke Hendriksen has discussed, here in Utrecht, we are building a new database of artisanal recipes. A quick search in the Artechne Database yields several fifteenth- and sixteenth century German recipes for green and yellow colors that call for buckthorn berries (some with precise indication for picking times, like this one for “Green color” from 1543). Here an Italian one from the anonymous Padua Manuscript (ca. end 16th/17th century), translated and published in English:

To make giallo santo

Take the berries of buckthorn towards the end of the month of August, boil them with pure water, until the water is loaded and thick with color; add a little burnt roche alum and then strain it. You may boil the strained liquor to make the color deeper, mixing with it some very pure gilder’s gesso; then make the color into pellets, and dry them in the shade.[6]

In color recipes such as this one, seasonality and intimate knowledge of seasonal products sensitivities to additives play a key role. Berries had to be picked at specific times of the year to attain the right hues, and while the juice of ripe buckthorn, available in most of Europe, gives a greenish color, also known as sap green, one needs to get hold of unripe berries, fresh or dried, in particular a species imported from the Middle East, also known as “Persian berries”, to attain the deep golden yellow hue that the reconstruction team had envisioned for this dazzling sixteenth-century dress.[7] Only by patiently repeating the dye processes using the right berries picked at the right moment, can the desired vibrant hue of rich quality be achieved – both in the early modern period and during 21th century reconstruction.[8]

Thus, the commission of brightly dyed dresses for display at important events must have been a time-consuming affair that required planning long ahead of the political event and entailed a collaborative process of sourcing and experimenting that depended not only on seasonal knowledge and availability, but was also prone to risks of seasonal change. As Rublack’s work shows, reconstruction research makes us of acutely aware of the complexities and risks posed to those who aspired a part in the “chromatic politics” of the Holy Roman Empire in the sixteenth century. Moreover, as I will show in my next post, color recipe reconstructions allow us to experience the efforts and knowledge that went into the creation of early modern color worlds, which have become unfamiliar to our modern period eye.
