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.

Al the Britons doe dye themselues wyth woade: experimenting with woad and its history

We are, apparently, living during a ‘post-truth’ time when alternative facts have just as much impact on some people’s decisions and beliefs as, well, fact facts. The concept of the “alternative fact,” which refers to promoting emotional or biased assertions over facts, has historic precedent. Julius Caesar, when documenting his campaigns in Gaul, noted that:

Al the Britons doe dye themselues wyth woade, which setteth a blewish color vppon them: and it maketh the more terryble to beholde in battell.[1]

Surely if woad were so widely available, there would be decent archaeological evidence for its application. There is one early find at the Iron Age site of Dragonby. The site revealed woad remains, in the form of seeds and pods, as part of a waterlogged assemblage from a late Iron Age pit. The exact purpose of the pit has not been identified.[2] The seeds and pods can be considered circumstantial evidence when it comes to claiming that the plant was introduced for its dye because the material needed for dyeing, the leaves, may not survive nearly as well. The difficulty of finding woad leaves archaeologically means that we can only rely on the indirect evidence of the plant as a possible dye from Dragonby.

As a conqueror displaying his military strength and emphasizing the legitimacy of his triumph, Caesar may have called on Romans’ traditional concepts of fierce barbarians. Blue had negative connotations within Greco-Roman culture, being associated with ghosts, death, and, perhaps worst of all, barbarians.[3] By including such a charged description of ‘blue’ Britons, Caesar set down more than an ethnographic account. He used existing preconceptions for his political advantage. It is doubtful, however, that Caesar conceptualized the lasting legacy his charged description would have on social memory and identity. Even today, it is common to see depictions of ancient Britons painted blue, despite limited botanical-archaeological evidence and possible evidence to the contrary. The image of bluely decorated warriors can be found everywhere from the early 20th century, one example being the National Anthem of the Ancient Britons and another the anachronic depiction in the movie, BraveHeart.[4]

But, why?

Because it’s tradition, apparently. The 1565 translation of Caesar’s De Bello Gallico, above, translates the word vitrum as woade (woad, Isatis tinctoria). This translation, by Arthur Goulding, is the earliest I’ve identified. Gillian Carr and several others give other possible translations as being “dye themselves with glazes” or “infect themselves with glass.”[5] So why is vitrum so often translated as woad in this context?

Woad was an important crop for some English abbeys during the medieval period, and a key crop in England in the sixteenth and seventeenth centuries.[6] What better way to form a defense against an encroaching foreign material than to highlight the cultural importance of its proud, “indigenous” counterpart?

Enter vitrum as woad. Caesar may not have a historical monopoly on shaping a narrative to support a cause. In fact, he may not even have a monopoly on shaping his own narrative to support a cause. Still, just as there is limited evidence regarding the use of woad in ancient Britain, there is limited evidence supporting the reasons behind the historical trend in translating vitrum as woad.

Despite the potential mistranslations and lack of archaeological, textual, and iconographic evidence, people are still interested in the question, “does it work?” Without a recipe or replicable evidence, experimentation depends primarily on how other pigments are made ethnographically or in the past under other conditions and contexts. We know woad is a dye, and we know that it can color the skin and that it can be added to a binder to make a pigment. Some experiments reveal that woad, when compared to our perceptions of its color and use, is a poor choice for corporal decoration in terms of dyeing, tattooing, or staining the body. Want to replicate the results of these studies or develop your own? Carr describes her experiments in her article, and a link to my initial methodology and experimental recipes can be found in the footnotes below. Find out for yourself whether it works by using woad and other pigments and dyes to paint or dye your skin blue.[7]

Sharing research and experimental results is one remedy to the promotion of potentially alternative facts (such as blue Britons) through critical engagement of evidence. The lack of recipes or physical remains is a challenge, but it is also an opportunity to encourage the exploration of other materials, methods. The confusing, and possibly sordid, history of woad in Britain also provides an opportunity to explore not only the history of translations of Caesar’s works and how identity and social memory reflect our relationship with plants, but it is also an interesting context in which to explore the use (or misuse) of woad.

Theodorus Priscianus’ recipes for breast engorgement

By Louise Cilliers

We know very little about Theodorus Priscianus, only that he was a student of the famous Carthaginian physician, Vindicianus (late 4th century CE), and was thus also a native of North Africa. We can also deduce that he was a professional doctor. The work for which Theodorus is known, is the Euporiston (a book of easily obtainable remedies), which consists of four books of medical recipes, of which the fourth, the Gynaecia, contains treatments for women’s diseases. Due to its practical applicability, the Gynaecia was very popular in the later Middle Ages; it was excerpted on numerous occasions.

The Gynaecia is dedicated to a midwife, a certain Victoria. In his preface, Theodorus states that he wants to “support her with his knowledge”, and he requests her to “faithfully, diligently and carefully… carry into effect the remedies for female ailments” as set out in his treatise. This knowledge was then to be disseminated among midwives and other women to help them in treating ailing women.

Theodorus’ Gynaecia comprises recipes for ten female ailments which he discusses. They are: engorgement of the breasts after parturition, swelling or contraction of the uterus, the mole, atresia, sterility, abortion, haemorrhage of the uterus, injuries to the uterus, the flux, and gonorrhoea. I will focus on engorgement of the breasts after parturition.

This is a very common problem that women experience after having given birth, and various procedures, such as poultices laid on the breasts, were followed in ancient times. Medicaments, made from vegetables and herbs used in the kitchen, were also given. Theodorus clearly has empathy with women whose breasts are taut, swollen or painful after birth. In not too serious cases, he recommends that a soft sponge soaked in a mild astringent, such as vinegar, be applied to the breast, and held in place by a light bandage. Alternatively soothing poultices, for instance, bread soaked in water-mead and oil or fresh pork fat can be laid on the breasts.

If the problem of engorgement has been resolved but the mother still wants to feed the baby, the breasts should be smeared with rush, egg and saffron, or crushed raisins mixed with the flour of beans, or pounded sesame seed mixed with vinegar and honey, or a mixture of pounded leaves of ivy and figs, or (even more directly from the kitchen) fresh pounded cheese with vinegar-honey – if these substances be made into a poultice, they would apparently have increased the fecundity of the milk.

If the patient cannot bear the weight of the poultice, the breasts must be steamed, and an even softer sponge soaked in an extract of marsh mallow, linseed and fenugreek plants be applied.

But if milk production should be stopped completely, alum or the seed of fleawort or coriander of purslane must be added to the aforementioned poultice, or the powder of a pounded millstone mixed with a wax salve should be applied. But if the breast has produced pus, it must be opened with appropriate aid, so that with one voiding they can be healed completely.

Throughout Theodorus warns that medicaments should be mild, and that all poultices should be applied with moderation, with consideration for the tender breasts.

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.
