Tales from the Archives — Recipes Against the Supernatural

In September 2017, The Recipes Project celebrated its fifth birthday. We now have over 600 posts in our archives and over 150 pages for readers to sift through. That’s a lot of material! (And thank you so much to our contributors for sharing such a wealth of knowledge on recipes.) But with so much material on the site, it’s easy for earlier pieces to be forgotten. So, the editors have decided that, every now and then, we’ll pull something out of the archives to share with our readers anew.

Today is Halloween. HALLOWEEN! Many of us recipe people who work on the premodern period have a fondness for Halloween, with its connections to charms, alchemy, cauldrons bubbling, and all. Yes, yes, I know… it’s really a love/hate relationship, as we often have to explain to people that supernatural beliefs were rationale and that most recipes weren’t about magic anyhow. But… HALLOWEEN!

To that end, I’ve pulled out only one of our many posts on the magical world. Catherine Rider offers here some thoughts on what charms might tell us about the connection between the supernatural and illness. There is even a protective charm for those ‘sleeping, waking, drinking, eating, and especially dreaming’…

You never know what might be useful on this day of lowered boundaries between natural and supernatural worlds!

By Catherine Rider

I’ve been thinking recently about a kind of recipe I’ve been collecting for some time, with an eye to using them in a future project: recipes that protect against evil spirits and other supernatural entities. These take the form of charms, made up of spoken and written words, rather than more conventional mixtures of plants or animal parts.  As Laura Mitchell has noted before on this blog, many medieval recipe collections (such as the one in the Wellcome Library pictured below) include charms alongside other remedies.

Research by Lea Olsan, Eamon Duffy and other scholars has shown that although some medieval physicians and churchmen were uncomfortable with charms, most writers accepted them as legitimate cures for certain kinds of illness, including bleeding, toothache and epilepsy. They were also often regarded as a mainstream part of religious devotion.[1] Charms to ward off demons are not very common – nowhere near as common as charms against toothache or bleeding – but I’ve found several examples in fourteenth- and fifteenth-century recipe manuscripts.

The version given, in Latin, in a fourteenth-century recipe manuscript published by Fritz Heinrich begins ‘In the name of the Father and the Son and the Holy Spirit, Amen,’ and goes on to list a series of saints and other objects of devotion commonly appealed to in late medieval prayers: Virgin Mary, the four evangelists (Matthew, Mark, Luke and John), the Cross and the Passion, and the Five Wounds of Christ. This prayer is to be written down and God is implored to protect the person who wears these words when they are ‘sleeping, waking, drinking, eating, and especially dreaming’, ‘from every malign demon and every malign spirit and the instigations of the devil.’[2]

This charm, and others like it, are raising quite a few questions for me:

  • Bishop exorcising possessed men, 15th century. Image credit: Wellcome Library, London.

    They’re not that common.  Does that mean that demonic assault was not regarded as a common condition?  We do find accounts of ‘possessed’ people in the miracle collections kept by saints’ shrines, so clearly the idea of demonic attack was not unknown.  However, these cases may have been notable because they were unusual, not necessarily because they were common.

  • What symptoms or conditions were attached to this charm?  The reference to sleeping and ‘especially dreaming’ suggests bad or troubling dreams, rather than an illness. Another possibility is the medical condition which medieval physicians called ‘incubus’, in which a person feels a presence pushing down on them in their sleep.[3]  It is usually equated by historians with the condition now called sleep paralysis.  Educated medieval physicians generally argued that this condition had physical rather than supernatural causes, but they also noted that ‘some people’ believed demons were behind it.
  • There are also questions about continuity and change over the longer term.  Do we get more of these charms from the sixteenth century onwards, when we see rising concerns about witchcraft and more intellectuals taking an interest in demons and demonic illnesses? We know that magical illnesses continued to be a concern and Jennifer Evans discussed some early modern remedies for them in 2012 in a column for the Societas Magica newsletter.  Also, what happens to this kind of medieval charm after the Reformation?  Did it appear too Catholic with its saints and Latin?  Were there Protestant equivalents?  Or did it continue to be copied despite its old-fashioned elements?
  • Was this charm used? And, if so, how? It would need someone who could write it down, and ideally someone who was familiar with Latin. By the late fourteenth and fifteenth centuries, that could include some medical practitioners and educated laypeople, but clergy also owned manuscripts of medical recipes and might be best placed to use this kind of charm.

I don’t have the answers to these questions yet, but in the long term I’d like to build the charms in to a larger project on supernatural illnesses in medieval medicine and I’m hoping that small pieces of evidence like these might eventually start to offer a bigger picture.

Sugar versus honey in Byzantine recipes

By Petros Bouras-Vallianatos

The Byzantine Empire, with its capital in Constantinople (now Istanbul), then a mainly Greek-speaking region, constituted a natural crossroads between East and West for more than a millennium (AD 324–1453). Its history is an indispensable part of the medieval period in both Europe and the Middle East. In the field of medicine, for example, we can attest to widespread interactions with the Islamic tradition.

The most dynamic part of Byzantine therapeutics was pharmacology. We are privileged to have several surviving pharmacological manuals, especially dating from the later period, i.e. from the twelfth to the fifteenth centuries, which provide us with a unique testimony to Byzantine composite drugs. Here I have selected the example of sugar-based potions, as it offers an excellent case-study that helps us to better understand the way Byzantine recipes were developed through a process of both practical experimentation and influence from outside.

Before the introduction of sugar, people relied on honey to make medical potions sweet. Greek and early Byzantine medical authors referred to honey-based drugs such as oinomeli (a mixture of honey with wine), hydromeli (a mixture of honey with water) or oxymeli (a mixture of honey with vinegar). For example, Paul of Aegina (fl. first half of the seventh century) recommends the following recipe for those suffering from calculi:

One ounce[1] each of saxifrage, betony, dog’s-tooth grass, maidenhair fern, spikenard, carpesium, hazelwort, and eryngo; one half ounce each of Macedonian parsley and seed of rue; two ounces each of green fennel, iris, baked squill, and periwinkle; three ounces of bark of the root of capper; two ounces of water-parsnip; and two sextarii[2] each of water, vinegar, and honey.[3]

Meanwhile, the cultivation of sugarcane gradually spread throughout the Islamic East from the seventh/eighth century onwards. Sugar was used as a simple drug, for stomach ailments and the relief of pain in, for example, the chest and kidneys. However, it also became popular as an excipient in liquid pharmaceutical dosage forms, used as a sweetener and preservative, initially supplementing and gradually replacing the use of honey for pharmacological purposes in the Islamic world. Sugar is of higher purity than honey, thus a smaller quantity has a stronger preservative action; it is also less susceptible to changes of temperature and ensures greater homogeneity into the final product. Among the most commonly used potions in Islamic medicine are the so-called julep (julāb) and syrup (sharāb), both of which consisted of sugar and one or more kinds of fruit juices or extracts of flowers.

By the eleventh century sugarcane cultivation was thriving in Syria and Palestine, eventually reaching the large Mediterranean islands of Cyprus and Sicily. Western merchants, such as the Genoese and the Venetians, played an important role in the distribution of this commodity throughout the Mediterranean, including Byzantium. For example, sugar is mentioned among the main supplies for the newly established Byzantine hospital (xenon) of the Pantokrator Monastery in Constantinople in the early twelfth century, but it was not until the late thirteenth century that sugar became widely available in the Byzantine world.

At the same time, we can observe the transfer of medical knowledge to Byzantium through translations of Arabic and Persian works into Greek. The earliest text of this kind, which preserves a large number of references relating to the various kinds of sugar-based potions, is the Greek translation of Ibn-Jazzār’s (fl. tenth century) Ephodia tou Apodēmountos (Zād al-musāfir wa qūṭ al-ḥāḍir/Provisions for the Traveller and Nourishment for the Sedentary), which must have been translated in the late eleventh/early twelfth century by scholars working in Southern Italy. By the early fourteenth century recipes for sugar-based potions had become very common in Byzantine manuals. The Constantinopolitan medical author and practising physician John Zacharias Aktouarios (ca. 1275–ca. 1330) provides an extensive list consisting of about thirty recipes, and he often explicitly acknowledges that he was introducing a new recipe. For example, he gives the following recipe for a julep for heart palpitations:

One hexagion[4] of the three sandalwoods; three hexagia of violet; two hexagia of basil seed; two hexagia of rose; five hexagia each of bugloss and ox-eye flowers; two hexagia of aloeswood; one hexagion of ambergris; two hexagia of saffron; three hexagia each of dried flower-buds from the clove-tree and nutmeg; one hexagion each of cinnamon, anise, caraway, and fennel seed; five grains of musk; one hexagion of poppy seed; three ounces of the juice of sweet apples; one ounce of rosewater; five ounces of distilled endive water; one ounce each of the roots of fennel, wild celery, and chicory; three hexagia each of marjoram, chamomile, and wormwood; and three ounces of sugar.[5]

In this recipe, in addition to sugar, we can also see ingredients from Asia and the Far East, such as musk, amber, and sandalwood, which became common in European pharmacology, especially during the thirteenth and fourteenth centuries after the Mongols’ conquests in Eurasia that led to the Pax Mongolica and the resulting improvements in trading conditions. To sum up, the fact that Byzantine physicians were aware of the usefulness and effectiveness of these sugar-based potions and made extensive use of them is at odds with the established view that Byzantine society was not very open to outside influence. Nowadays sugar is omnipresent and often replaced by sugar substitutes for the sake of diabetics and the diet-conscious; but once it was a novelty and highly desirable!

The Live Chicken Treatment for Buboes: Trying a Plague Cure in Medieval and Early Modern Europe

By Erik Heinrichs

While researching German plague treatises I became fascinated by one odd treatment for buboes that appeared again and again, despite sounding so far-fetched. One sixteenth-century version calls for plucking the feathers from around the single hole in a chicken’s backside, then placing it on a person’s bubo. The instructions say to hold the chicken on the bubo until it dies, when it must be replaced with a new chicken, similarly plucked. I soon dubbed this the “live chicken treatment for buboes” and after years of casual encounters I began to track the recipe more systematically. As strange as it sounds, versions of this “live chicken treatment” were fairly common in plague writing, beginning with the Black Death and lasting, amazingly, into the eighteenth century. Tracing the long history of this recipe led me to explore questions such as: Where might this come from? Why chickens? Why might healers think that this was a good idea? Did anyone actually try this or is this all theoretical? As a historian, I was also interested in change over time within the recipe. Here I found much to explore, as I followed the recipe’s twists and turns over a seven-hundred year period, roughly 1000 to 1700.

The “live chicken treatment” turns out to have a long history, indeed. Its origins seem to lie in Avicenna’s Canon of Medicine, although it may be older than that. Chickens and chicken broth were a common source of medicine in early times, probably because chickens were such ubiquitous and useful animals since antiquity. Not only did Avicenna praise chicken broth for its general benefits for the body, but he also recommended placing a cut chicken on a poisonous bite or sting in order to fight poisons. In later centuries European physicians turned to Avicenna’s advice when they faced the mysterious and devastating epidemics of the fourteenth century. As Europeans emphasized the poisonous nature of the plagues around them, older treatments for poisons drew new attention. The first mention of using a chicken rump to draw poisons out of a bubo appeared in the very first plague treatise of 1348, coming in response to the so-called Black Death. Here the Catalan author Jacme d’Agramont seems to have introduced a novel and lasting adaptation of Avicenna’s recipe, although the “cut chicken” version persisted in plague treatises for centuries to come.

Most interesting for the history of trying and testing cures are the many variations of the “cut chicken” and “chicken rump” versions of the treatment, as well as physicians’ comments about how effective they are. Especially after 1400, physicians seem to be thinking about this recipe quite often as they seek practical treatments for the plagues of the time. Physicians were preoccupied with altering the recipe in order to reason out the nature of the mysterious poisons underlying the plague. Some add substances to the process, such as salt placed on top of the chicken as it is placed on the bubo. During the fifteenth century, a number of German physicians began to explain the treatment’s workings in a strikingly physical way—that the chicken breathes through its backside and thus pulls the bubo’s poisons into itself. This change led to the suggestion to hold the chicken’s beak shut during the treatment in order to force the chicken to breathe from below. My article (accessible here) show how all aspects of the treatment changed over time as physicians engaged with the recipe, including the quantity of chickens used, the amount of time required, and even the type of animal in question. This work demonstrates the importance of the recipe itself as a platform for thought, experimentation, and communication among physicians.

Perhaps a surprise to modern readers, many physicians praised their version of the “live chicken treatment,” describing it as effective and desirable. Such comments multiply after the introduction of print, which encouraged the production of plague treatises, some fitted with fetching cover illustrations for the marketplace (see image below of Philippus Culmacher’s treatise of circa 1495). In German-speaking lands especially, sixteenth-century physicians used their printed plague treatises to promote their own services and expertise at a local level.[1] This brought about a change in the genre whereby physicians seem more eager to discuss their own experiences with effective recipes in order to appeal to the practical interests of a broad audience. Amidst this change comes evidence that some German physicians witnessed first-hand the successful use of the “live chicken treatment.” Another interesting change during the sixteenth century is the increased attention to the bodily warmth of the chicken as the treatment’s active healing force. These emergent views provide a tantalizing link to modern medicine, since moist heat remains one of the treatments for buboes today. For more information, please read my article.

As readers of this blog well know, early modern Europe was aflood with recipes and drugs. One central question has long preoccupied many of us –  just how did our historical actors assess, test and try out recipes, drugs and materia medica? A few summers ago, a group of historians of science and medicine gathered to discuss just this question. This month, we present our ideas and findings in a special issue of the Bulletin of the History of Medicine. To celebrate the launch of the special issue, several authors of the volume will share their work on The Recipes Project. Tuesday’s post revisited Ashley Buchanan and Tillmann Taape‘s report on the original 2014 conference. Over the next few weeks, we’ll learn more about the research of Erik Heinrichs, Valentina Pugliano, Alisha Rankin and Justin Rivest. Finally, Tillmann Taape, who just completed his PhD at the University Cambridge (congrats!) also adds his voice to the series by reflecting on how theme of drug testing features in his doctoral dissertation.

To get us started on our month of ‘Testing Drugs and Trying Cures’, we wanted to say a few words as the organizers and editors of the project. First, you might ask, what do we mean by ‘Testing Drugs and Trying Cures’? Over the course of the project, we found that it was useful to view ‘testing drugs’ and ‘trying cures’ as two overlapping but distinct phenomena.

As the essays in the special issue show, physicians and apothecaries developed clear rules and practices for testing drugs as materials – from sensory analysis of materia medica to chemical analysis of substances like mineral waters or alchemical medicines. This kind of ‘testing drugs’ largely focused on gaining knowledge on the substances’ medicinal properties and played a particularly significant role in the discovery and adoption of materia medica from the New World and in assessing and establishing authenticity of exotic and/or expensive medicaments.

‘Trying cures’, on the other hand, describes the widespread practice of trying remedies and other kinds of cures on human bodies. If ‘testing drugs’ was mainly conducted by learned physicians and apothecaries, ‘trying cures’ was performed by a broad range of healers. Within the home, women and men applied and observed the effects of remedies on family and household members. Likewise, physicians and other practitioners prescribed diets, medicines and other cures to their patients, again observing and recording the effects. Ample evidence of this kind of ‘trying cures’ survive in a range historical sources from the use of ‘probatum est’ to expressions of personal experience, customisation and rejection of recipes in household recipe collections (for more on this, see posts here and here).

For us, these two categories ‘testing drugs and ‘trying cures’ serve as helpful heuristic tools to untangle the assessment practices used by early modern practitioners. We see the two categories not as separate boxes but rather as overlapping and often intertwined practices. Many healers merged testing and trying by using patient tests to determine a substance’s properties or to refine methodologies in both drug production and application. These themes of testing and trying occupied a central place in the making of medical knowledge across a vast chronological span and broad geographical regions and social contexts. The essays in the special issue examine these crucial knowledge practices in Europe c. 1300-1800 (go here for a table of contents).

Several main themes emerged from this collaborative project. First, medicine was always an experiential art and the essays in the special issue demonstrate clear continuities between the learned physicians’ uses of experience/experiment in the Middle Ages and early modern experimental interests. Learned medicine made deliberate use of experience from a very early date and pharmacy was an area where the gathering of experiential knowledge was particularly pronounced. The senses – touch, taste, smell, sight and hearing – played vital roles in determining the properties of drugs and their effects on the human body.

Concurrently, as many essays in the volume demonstrate, structured drug testing had a long history. Medieval physicians developed meticulous rules for drug testing, as Michael McVaugh’s essay shows, although they left no record of actual medical trials. This focus on establishing protocols for drug testing continues throughout the medieval and early modern period, with significant expansion in scale and scope. By the eighteenth century, the testing of mineral spa waters (in Michael Bycroft’s essay) or proprietary drugs (in Justin Rivest’s essay) became large-scale undertakings situated in learned academies and hospitals.

When taken together, the essays in the ‘Testing Drugs and Trying Cures’ special issue collectively argue that ‘experimental thinking’ played a crucial role in learned assessments of medicine and drugs throughout the Middle Ages and early modern period. From the time of Galen, drug testing was structured and evidence-based with an aim to produce transferable results. For us, this fascinating and multifaceted story of premodern drug testing enriches and extends current histories of experimentation and we hope that our explorations into topic will inspire others to join us too!
