Magical Charms, Love Potions, and Surreal Tricks

A compact fifteenth-century paper book, MS Sloane 1315 (British Library, London), stands as a manuscript witness to many of the works of popular Middle English instruction.

The book might be said to be a miscellany or multi-text manuscript that is home to vernacular works of the kind that were widely-read and much copied in the fourteenth and fifteenth centuries. Among its many texts is

  • a copy of the courtesy text The Boke of Nurture, purported to have been compiled by John Russell in the service of Duke Humphrey of Gloucester;
  • a treatise on lucky and unlucky days;
  • a leechbook;
  • a verse lunary called “The Thirty Days of the Moon” (extant in several manuscripts of this kind);
  • an abridged version of the widely-circulated Wise Book of Philosophy and Astronomy;
  • a copy of the popular herbal known as the Agnus Castus;
  • a medical regimen with the title “A Generall Rewle for to yeue Medycyns”.

But why stop there? Sloane 1315 also preserves a dietary, and is well-illustrated with useful diagrams, charts, and curative aids in the form of calendars and astrological tables. There is even a homo signorum at ff. 68–69.

The manuscript, originating in the south-east of England, is likely to have served a individual practising astrological and herbal medicine, collating a series of texts and tables that would have been useful to that individual.

The layout and page placements in the manuscript suggests regular consultation. For example, there are clear headings supplied throughout. Although the manuscript is in many ways unremarkable, it is clear and accessible, written in a legible cursive hand.

The book is, however, remarkable in one aspect. In the midst of the many works is a curious collection of short medical recipes, interspersed with a series of short texts that might be described as recipes and charms. Some of these recipes are magical or fantastic, or contain properties associated with illusion or trickery. Laura Mitchell has previously written at The Recipes Project about ludic and lascivious medieval charms.

The ones in Sloane 1315 are strangely at odds with the rest of the texts, sitting rather uncomfortably with the diagnostic and curative theme of the volume as a whole. They are extremely varied, to the point of almost being random: some of the more extreme examples with spell-like qualities include charms to “make a flodde of water to com into a howse”, to “make a lofe of brede to dawnce in an oven or on a tabull” (which calls for the use of quicksilver), and “to make a howse seeme full of snakys.”[1]

There is a method as well to “make a lampe to bren wythowte fyre”, which seems to involve soaking a wick in oil, and one to “make a whyte spotte on a blacke horsse”, which involves anointing a horse with water which has been steeped in a special herb. One that caught my eye (and too late for Valentine’s Day 2019!) is a short instruction “How to Make a Woman to love the”, which I transcribe here (with light edits):

Take the harte of coluere and bren hit on a ty3le ine to powder, and yeve here thereof in mete or dryncke; and sche schall love the

The text calls for the “harte of a coluere” – the heart of a snake – to be burned and ground into powder, then sprinkled into the food or drink of a woman. It reads like something that students at Hogwarts might create using snake fangs or skins in their Potions lessons, and indeed this section of the book has a fictive quality to it: we cannot imagine that any of these instructions could possibly work by delivering what their titles promise.

However magical and impossible they might be, moreover, they are framed as recipes, manifesting many of the same features as the recipe text-type while also bearing some relation to charms. The “take and make” formula that is so familiar to us–and common to premodern recipes–is interrupted only slightly by the strangeness of the ingredients and the apparent simplicity in achieving what seems to be rather a difficult effect.

All things considered, these recipes do seem to fit their context. Sloane 1315 is clearly a manual for giving care, containing works that will be familiar to any student of medieval astrological and herbal medicine. The strange recipes are not textually distinguished from other works in the volume; rather, they are normalised, and look as if they are intended to fit in with the book’s other contents. Their regular appearance masks their unusual qualities, and though the love-recipe might seem at first fairly innocuous, the fact that it and its co-texts are disguised to dovetail with the other works in the book may give us pause. In short, the fantastic nature of these texts may not sit well with the pretty practical bent of the book as a whole.

They cause me to pause because they recast the way in which I think about the rest of the book. On the one hand, they may have been used in unscrupulous ways. If, as literary scholar Douglas Gray observes, this is the kind of manuscript that would have been used by “leeches, ‘wise women’, and ‘cunning men'”, then these people would have occupied positions of trust in a community (35). Can we countenance, then, the possibility that the individual who owned this book may have been involved in a lucrative side-line, peddling recipes that didn’t work and perhaps selling the ingredients as well: quicksilver, snake’s hearts and skins? The recipes seem ripe for facile dissemination, being short enough to have been memorised or quickly copied, and they may have been used to bolster the credibility of the owner of the manuscript, showcasing his knowledge of strange or exotic methods or ingredients.

Or perhaps their function is altogether different. Could they have been intended to introduce humour to the healing context? Perhaps they functioned like the modern-day prank box, a kind of textual cabinet of curiosities, intended to entertain clients who were not feeling well, or appealing to younger audiences? As Gray writes, one can “sympathize with the curious owner or reader eager to discover” the varied arts described therein, and the owner of the book may have just wanted to spread some joy and mischief (35). What we read here may be an entirely personal impulse to collect (or create) fun from a pretty standard, recognisable textual tradition and format. Or perhaps the book provides further evidence of the close relationship between medicine and magic in this period (that persisted in some contexts in later centuries; see Lisa Smith’s post on an eighteenth-century magical manuscript), giving expression to a particular understanding of popular medicine as, in some respects, fanciful? Whatever the scenario, Sloane 1315 is a fascinating volume, hiding amongst its popular medical works a collection of weird and wonderful textual gems and raising all sorts of questions about the varied role of the folk practitioner in this period.

How to correct Plato, alchemically?

By Bojidar Dimitrov, AlchemEast Project

Jabir Ibn Hayyan is a figure of key importance for the development of alchemy and chemistry. A vast body of literature virtually covering the entire spectrum of ancient science has been attributed to the Islamic polymath, and yet much of the little we know about him remains shrouded in mystery. The very historicity of Jabir’s person and the authenticity of his works have been the subject of rigorous scholarly debate. This is largely due to the fact that the majority of the texts which belong to the Jabirian corpus have not been edited and published.

The scant biographical data provided by mediaeval Islamic sources and Jabir’s own works suggests that his lifetime spanned the period between ca. 721/725 and 812/815 AD. The so-called Jabir Problem mainly revolves around different aspects of this alleged historical context. The ambiguous relationship between the Arabic Jabirian corpus and the nascent alchemical tradition of the Latin West is the other major side of the conundrum. 

Paul Kraus’ ground-breaking studies on Jabir[1] proposed that the Jabirian corpus was probably compiled over a longer period of time by a school of alchemists who circulated their works under Jabir’s name. Similar doubts were already expressed by mediaeval Islamic scholars, and Kraus’ detailed analysis of the language and the content of seminal texts argues that the scientific terminology, doctrines and references to Greek authorities found in them point to a later stage of Islamic intellectual history, which began in the ninth century. Kraus’ conclusions have been debated by scholars since their publication in the 1940s, but the scope and depth of his research remain unmatched to this day.

One of the current objectives of the AlchemEast Project is to make available a collection of alchemical recipes belonging to a sub-genre of Jabir’s corpus. Plato’s Rectifications is the only surviving collection of a cycle of pseudepigraphical ‘rectifications’ associated with ancient authorities. The work is presented as a commentary on alchemical doctrines ascribed to Plato that the Greek sage is said to reveal to his disciple, Timaeus. The ninety recipes involve alchemical procedures with mercury which are intended to illustrate the application of Plato’s theories.

Socrates discussing philosophy with his disciples (from a thirteenth-century Arabic manuscript).

Jabir’s attribution of alchemical material to Plato is pertinent to the reception of Platonic influences in Islamic alchemy and the wider context of Islamic thought. While Jabir’s system incorporates key Neoplatonic traits of Greek philosophical alchemy, its experimental and arithmological developments are highly original and do not seem to derive from extant Greek texts. Furthermore, no alchemical texts are attributed to Plato (or Socrates) in the Greek tradition.[2] There are, however, Syriac recipes attributed to Plato, and he is generally accorded a prominent place in Arabic occult literature. Such facts may indicate that Jabir could have been influenced by late antique Neoplatonic traditions of a distinctly Near Eastern flavour.

An excerpt from Rectification Nr. 14 presents a recipe which involves the heating and cooling of mercury:

Then he said: take ten measures of spirit (i.e. mercury), put it in the middle gourd (i.e. glass vessel), and tighten upon it the alembic which has no aperture (i.e. valve). Heat it over gentle fire for ten days, then cool it off on the eleventh. Repeat the operation and gather the first water. The gourd containing mercury will be heated, or joined to the other gourd until it (i.e. mercury) dissolves in one of the two gourds. Take the thickened [residue], put it in the second gourd, and heat it until it melts, becomes liquid and turns red. Then heat the water until it boils and [the condensate] starts dripping all over the residue, [so that] it swells, absorbs some of the water and is incerated by it, and yields. It will become like wax, just as we described initially, and [even] better. If the procedure starts by heating the water until [the condensate] drips over the residue, it will be dissolved, and both will be dissolved, coagulated and incerated together, [and thus the procedure] is also complete. Peace.

The text exemplifies the fluidity of content that alchemical recipes often exhibit. The procedures it describes are relatively simple, but the textual variants in the manuscripts allow different possibilities. The translation above is not conclusive, since the relationship of the alembic and the two vessels is somewhat ambiguous. According to certain readings, for instance, the second vessel and the alembic must be alternated during the process of dissolution. The examination of further textual variants and manuscripts can expand our understanding of Jabir’s technical methodology. Ultimately, the intertextuality of Platonic pseudepigrapha found in Jabir and other traditions calls for an overarching discussion of Plato’s role in alchemical discourse. Whether this role was itself rectified by practitioners over the centuries, or the fluctuations we encounter in manuscripts are of a purely textual nature, are the main questions AlchemEast aims to address.

Sloane Family Recipes

By Lisa Smith

The famous eighteenth-century physician, Sir Hans Sloane, occasionally pops up in the pages of The Recipes Project, with patients keeping recipes or Sloane collecting manuscript recipe books. And, although the Sloane family had an illustrious physician and collector in their midst, they collected medical recipes like many other early modern families. Three Sloane-related recipe books that I’ve located so far provide insight into the family’s domestic medical practices and emotional lives.

Elizabeth Fuller: Collection of cookery and medical receipts
Credit: Wellcome Collection, London.

Two books are held at the British Library, donated in 1875 by the Earl of Cadogan. A book of household recipes, primarily for cookery, was owned by Elizabeth Sloane—Sloane’s daughter who married into the Cadogan family in 1717 (BL Add. MS 29739). The second book, c. 1750, contained medical, household and veterinary recipes (BL Add. MS 29740), including several attributed to Sir Hans Sloane. A third book, which belonged to Elizabeth Fuller, is held at the Wellcome Library (MS 2450) and is dated 1712 and 1820. Given the initial date and name, it is likely that the book’s first owner was Sloane’s step-daughter from Jamaica, Elizabeth Rose, who married John Fuller in 1703. Sloane’s nephew, William, married into the Fuller family as well in 1733.

Elizabeth Sloane, of course, compiled her collection long before her marriage; born in 1695, she was sixteen when she signed and dated the book on October 15, 1711. This was a common practice for young women who were learning useful housewifery skills. The handwriting in the book is particularly good, with lots of blank space left for new recipes, suggesting that this was a good copy book rather than one for testing recipes. There are, even so, some indications of use: a black ‘x’ beside recipes such as “to candy cowslips or flowers or greens” (f. 59), “for burnt almonds” (f. 57v) or “ice cream” (f. 56). The ‘x’ was a positive sign, as compilers tended to cross out recipes deemed useless.

The Cadogan family’s book of medicinal remedies appears to have been intended as a good copy, but became a working copy. In particular, the recipes to Sloane are written in the clearest hand in the text and appear to have been written first. Although there are several blank folios, there are also multiple hands, suggesting long term use. There are no textual indications of use, but several recipes on paper have been inserted into the text: useful enough to try, but not proven sufficiently to write in the book. As Elaine Leong argues, recipes were often circulated on bits of paper and stuck into recipe books for later, but entering a recipe into the family book solidified its importance—and that of the recipe donor—to the family.

Sloane’s recipes are the focal point of the Cadogan medical collection. Many of his remedies are homely, intended for a family’s everyday problems: shortness of breath, itch, jaundice, chin-cough, loose bowels, measles and worms. There are, however, two that spoke to his well-known expertise: a decoction of the [peruvian] bark (f. 8v)—something he often prescribed–and “directions for ye management of patients in the small-pox” (f. 10v).

Elizabeth Fuller compiled her book of medicinal and cookery recipes several years after her marriage and the book continued to be used by the family well into the nineteenth century. The book is written mostly in one hand, but there are several later additions, comments and changes in other hands. The recipes are  idiosyncractic and reflect the family’s particular interests: occasionally surprising ailments (such as leprosy) and a disproportionate number of remedies for stomach problems (flux, biliousness, and bowels). The family’s Jamaican connections also emerge with, for example, a West Indies remedy for gripes in horses (f. 23). There are no remedies included from Sloane, but there were several from other physicians.

This group of recipe books connected to the Sloane Family all show indications of use and, in particular, the Cadogan medical recipe collection and the Fuller book suggest that they were used by the family over a long period of time. Not surprisingly, the Fuller family drew some of their knowledge from their social and intellectual networks abroad.

But it is the presence or absence of Sloane’s remedies in the books that is most intriguing. Did this reflect a distant relationship between Sloane and his step-daughter? Hard to say, but it’s worth noting that his other step-daughter, Anne Isted (and her husband), consulted him for medical problems and the Fuller family often wrote to him about medical education, books, and curiosities.

Or, perhaps, it highlights the emotional significance of collecting recipes discussed by Montserrat Cabré. Sloane was ninety-years old when the Cadogan family compiled their medical collection.

It must have been a bittersweet moment as Elizabeth Cadogan (presumably) selected what recipes would help her family to remember her father after he died: not just his most treasured and useful remedies, but ones that evoked memories of family illnesses and recoveries.

But does it work? Playful magic and the question of a recipe’s purpose

By Melissa Reynolds

An early sixteenth-century recipe for “good gome” in Wellcome Library MS 406, f. 23r. Digitized images of the manuscript available at

One of the many pleasures of studying late medieval English “how-to” manuscripts is the wide and often surprising array of knowledge to be found within them. Most contain a good bit of medical information, such as herbal recipes and instructions for bloodletting, and many also contain useful household information, like directives for animal husbandry, fishing, hunting, sewing, ink-making, and so on. Also common to these collections are charms for curing fevers, staunching blood, and protecting women in childbirth. Some medieval English collections of recipes also contain magic of a lighter sort, like directions to “make a woman lift her skirts” or “to make thunder and lightning,” discussed in earlier posts by Laura Mitchell and Catherine Rider.

One such example of a light—and somewhat lascivious—recipe is found on folio 20 of Bodleian Library MS Ashmole 1389, a late fifteenth-century recipe collection compiled by William Aderston, probably a surgeon working in London.[1]

To make men & women to take off their clothes

Take grain with evil thistles [thystylls] which grow above the ditch & make from that a powder & put it in someone’s lap & immediately he or she will take off his or her clothes.[2]

Image credit: British Library, from Prudence Guilllaume de Roujoux, Histoire d’Angleterre (Paris, 1844), text added by Melissa Reynolds.

Certainly, as Mitchell has suggested, recipes like this one “to make men and women take off their clothes” are inherently playful. Yet I am also inclined to agree with Rider who points out that there is little evidence that medieval compilers drew a sharp distinction between lighthearted recipes and straightforwardly practical ones. In the case of Ashmole 1389, the recipe to make men and women shed their clothes appears within a short section of non-medical recipes in an otherwise overwhelmingly medical collection. Most other non-medical entries in the manuscript are clearly useful, like a recipe to make glue or instructions for fishing and engraving on metal.

So why was this recipe included in an otherwise useful collection, and what can its inclusion teach us about late medieval culture?

Historians can read 500 year-old recipes for medicine, agriculture, textile production, or cooking and understand why such knowledge was selected for “how-to” manuscript collections, even though the materials and techniques described are unfamiliar to us now. We can understand why so many collections feature useful, natural magic, as there was little distinction between magical and non-magical cures in medieval culture. In these cases, our understanding of the medieval recipe book rests on the basic premise that people wanted acces to useful (and useable) knowledge.

But recipes like this one “to make men and women take off their clothes” are perhaps more illuminating precisely because they don’t fit this mold. They challenge our presumptions about the purpose and function of a recipe. This recipe isn’t obviously practical, nor is it even apparent that it could be, or ever was, attempted by its compiler.

Though lighthearted magic like that in Ashmole 1389 is not nearly as common as healing magic, its presence in medieval collections should encourage us to reflect on what we expect from a recipe, and how those expectations color our historical interpretation. Perhaps we should ask ourselves if our focus on finding out how pre-modern recipes “work” always reflects the focus of pre-modern compilers and readers? Attempts at recipe reproduction can yield unmatched insights into pre-modern worldviews, materials, and techniques; hands-on and collaborative research into recipes should by all means continue! But while we’re building furnaces, making chacolet, and casting flowers, let us also remember that a pre-modern recipe might have had any number of meanings or uses for the pre-modern reader, some of which we may not yet fully understand.

[1]Aderston left his signature at the bottom of a recipe on folio 14v (“per me W. Aderston”) and a record at the National Archives of the UK contains reference to a “William Aderston, of London, surgeon” as plaintiff in a trespassing case against the sheriffs of London sometime between 1483–1515.

[2]Ad faciendum homines & mulieres deponere pannos suos / Accipe grana malignos cardenibus ^thys tylls^ qui crescunt super fossat & fac inde pulvere & ponite in gremio alicuius & statim exuet pannos. The Latin gremio could be “lap, bosom” or “womb; female genital parts.” You can see how a different translation would change the sense of the recipe entirely.
