The project “Selling the Exotic in Paris and Versailles, 1670-1730”, running in the Faculty of History at the University of Cambridge, and funded by Leverhulme Research Grant 2014-289, held its planned workshop in April this year. Its theme, “Consumers of the Exotic: European commerce and the consumption of exotic materia medica, 1670-1730”, brought together a group of international scholars working on these questions in a broad variety of European contexts.

Our goal at the workshop was to produce a comparative picture of the ways in which exotic plant materials were processed, bought and consumed in Europe. Why did European consumers buy—and more significantly ingest—exotic plant materials? What did exoticism mean to them? While recent work has focused on colonial bioprospecting and the appropriation of indigenous knowledge, our aim was to investigate demand within Europe itself, exploring divergences and similarities across contexts. The choice of a restricted timespan—the decades around 1700—provided a baseline for comparison of drug production, sales and consumption in different cultures. Alexandra Cook (University of Hong Kong) kicked off the programme with a study of a proprietary drug, Garcin’s “Maduran pills”, sold around Europe in the early eighteenth century by an entrepreneur whose Protestant faith led to a complex intellectual and commercial itinerary. Cook argued that exotic ingredients were not necessarily a selling point for eighteenth-century patients. Harun Küçük (University of Pennsylvania) provoked us to think about the complexity of defining the exotic, and the importance of a multi-perspectival view of the history of drugs: Ottoman healers associated New World exotica like cinchona bark and ipecacuanha root with French medicine, since these substances often reached them via French commercial and intellectual networks. Continuing the global theme, Samir Boumediene explored the place of drugs in the missionary activities of the Society of Jesus. The decades around 1700 represented a decline in the relative importance of Jesuits in the global drug trade, as new players came to disrupt their initial privileged position.

Šebestián Kroupa (University of Cambridge) offered a counterpoint to the workshop’s focus on European consumption by exploring the supply of European drugs to transplanted European populations—Manila in the Philippines. European drugs were in fact imported in large volumes to this “exotic” locale; little attention was paid to the pursuit of plant substances that might be commodified in the metropole, an exception being the Saint Ignatius bean. Victoria Pickering explored the diverse trajectories, contacts, and exchanges that were necessary to assemble the massive collection of exotic plant substances of Sir Hans Sloane.

Moving to early modern Russia, Clare Griffin suggested that its unique geographical connections—in the form of a land route between Europe and the Far East—led commentators to represent distant substances and peoples as subject to incorporation into the Empire, rather than “exotic” in the sense of “foreign”, as the case of rhubarb showed. Paula De Vos concluded the first day with an account of Palacios’ prominent 1706 pharmacopoeia. Early modern Western pharmacy was indebted, for its materia medica, to the Indo-Mediterranean world rather than the continent of Europe. The slow appropriation of new drugs spread outwards from this Indo-Mediterranean core to the Silk Roads, the Indian Ocean, and eventually the Atlantic world.

On day 2, Laia Portet explored the architecture of exoticism in printed French materia medica. Where familiar European plants tended to be classified alphabetically, unfamiliar exotics were classified by parts (roots, barks, leaves) since this was the form in which they entered the European marketplace. Emma Spary used a case history of an exotic aromatic, cinnamon, to point up the disjuncture between textual, material and empirical knowledge of drugs, a conundrum for medical experts, market regulators and individual consumers. Hjalmar Fors provocatively suggested that for early modern Europeans, “the exotic” primarily evoked traded material goods, including spices and drugs, rather than foreign peoples or distant geographies. Lack of knowledge about the places of origin of drugs was critical to a substance remaining “exotic” in European eyes.

Justin Rivest spoke of the encounter between political power, the emerging state and the large-scale administration of drugs in France, looking at how personal trialling of drugs by successive ministers of war led to a centrally administered programme of dispensing exotic drugs like tobacco, quinquina and ipecacuanha to French troops. In a very different take on the end-user, Wouter Klein introduced us to the uses of print culture as a research tool for relating newspaper advertising and ships’ cargoes of drugs in the Dutch republic after 1700.

Several common themes emerged from the papers. It seemed that “colonial bioprospecting” had its limits as a way of understanding European engagement with non-European materia medica. Most substances discussed did not reach Europe thanks to state intervention, but rather were trafficked by a heterogenous set of actors: missionaries, trading company officials, entrepreneurial merchants and court physicians. Many papers also showed that “exoticism” was not necessarily inherently desirable. A drug’s value was established through consensus-building over time. Furthermore, “exoticism” was a relative, context-specific category, subject to change, not solely a feature of geographic origin, or of a core-periphery relation between European metropoles and their colonies. The papers demonstrated that exoticism was also, perhaps largely, a product of degrees of familiarity and unfamiliarity, which varied widely across different European contexts. In sum, rather than being inherently valuable objects of appropriation, exotic drugs were socially constructed goods.

Distilling and Deflowering

By Peter Murray Jones

Between 1416 and 1425, English friars put together a Latin medical handbook. This handbook, called the Tabula Medicine (‘Table of Medicine’), mostly consisted of remedies, arranged alphabetically by name of ailment, instead of the head to toe order of the standard medical Practica. The friars seem to have assembled the text by accumulating remedies in a sort of medieval Wikipedia. Some copies preserve the ‘open’ format by leaving room for additional remedies under each heading.[1]

Many remedies are medicinal recipes culled from books. Most often they cite the works of Avicenna, Galen and native authorities, Gilbertus Anglicus, Bernard de Gordon, John of Gaddesden, and John Arderne. But a lot of other remedies are attributed to English friars who flourished c.1370-1420.[2] The friars mentioned were identified as authorities (expressed as “per fratrem Peter Russell”, for example) for recipes of all kinds. But they had a particular fondness for distillations. Under the heading “Gutta arthetica” (Gout of the joints), we find:

King’s MS 16, fol.1. The opening of the Tabula medicine

“According to brother William Holme, for cold gout take the dregs of a pottle (two quarts) of beer; boil down a pennyweight of boar’s flesh for a day, stirring it with a ladle; and take a handful each of chamomile, pellitory, cowslip, lavender, honeysuckle, and marjoram. Cut up the cooked meat and the herbs into tiny pieces and distill together with the dregs in an alembic. The water collected in a glass can be kept and used as wanted.  Apply it warm, and it is called flesh-water.”

Holme, like Hieronymus Brunschwig, held that distillation ensured your remedy did not go off.

More ambitious distillations aimed at producing the heavenly quintessence, or at the very least aqua ardens (burning water). The friars must have had a copy of John of Rupescissa, Liber de consideratione quintae essentie to hand, for they quote from it accurately under headings for “Cor” (Heart), “Demon,” “Facies” (Face), “Frenesis” (Frenzy), “Melancholia,” “Spasmum” [Convulsion] and “Venenum” (Poison). They never identify him by name, although Rupescissa was a Franciscan friar, writing from prison in France c.1350. Under the heading “Facies”, they tell us that wild strawberries are a hundred times more powerful against outbreaks of pustules on the face if administered as a quintessence. Rupescissa uses exactly the same words at two points in his text. We are not told in the ‘Table of Medicine’ how to extract a water from wild strawberries and combine it with quintessence, although Rupescissa does give a recipe.

The only heading in the ‘Table of Medicine’ that names a remedy instead of an ailment is “Balsamum” (Balsam). Native balsam was extraordinarily rare and expensive in late medieval Europe, in all its three forms, and friar William Holme is credited with two different recipes for making an ‘Artificial Balsam.’ One simply requires powdered exotic spices to be put successively into hot but not boiling oil. The second requires small quantities of natural balsam, as well as twenty-five other ingredients. They are mixed and pulped in a mortar before distillation. This distillate comes in three degrees of strength, and is said to be just as effective as the native kinds in treating a long list of ailments. Holme is the only one of the friars mentioned in the ‘Table of Medicine’ who can now be identified as author of a surviving text, De simplicibus medicinis (‘On medicinal simples’) of 1415. This was “deflowered” as the bibliographer John Bale later put it, by Holme “from twelve doctors of medicine”. The ‘Table of Medicine’ itself went in for “deflowering”, though it also credited experienced friar practitioners.

King’s MS 16, fol. 144. Wistanton’s recipe for distilling blood and Forman’s hand in the margin.

Friar Robert Wistanton gives a recipe to make use of distilled human blood in surgery. The blood is kept for forty days in a glass vessel under dung, then cooked in a copper pot for a day, cooled, then skimmed. Afterwards it is distilled with a filter, mixed with aqua ardens, then distilled again with an alembic, and that distillate is the best of all waters. It will consolidate a wounded limb within three days and heal the sick. What remains in the bottom of the vessel should be kept, cooled and dried, and the resultant powder is best for fractured bones. Friars were not supposed to dabble in alchemy and surgery, but that does not seem to have stopped Wistanton and his brothers.

King’s MS 16, fol. 8b. Insert in Forman’s hand on Catalepsis.

In 1574 Simon Forman, astrologer and alchemist, purchased a manuscript of the ‘Table of Medicine’ in Oxford. He added recipes drawn from his own experience, or from Andrew Boorde’s Breviary of Healthe (1557), in the margin opposite the entries for particular illnesses. He also interleaved the manuscript to add remedies for illnesses not covered in the ‘Table of Medicine’. In this enhanced form the text continued in use into the seventeenth century.[3]

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.

‘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.
