A few weeks ago I was fortunate to present a paper at the 24th International Congress on History of Science, Technology and Medicine (iCHSTM), which was held at the University of Manchester from July 21st to 28th. The congress operates under the auspices of the Division of History of Science and Technology of the International Union for the History and Philosophy of Science (IUHPS/DHST) and the 24th congress was organized by the British Society for the History of Science. Held every four years, this year’s congress had the theme of “Knowledge at Work”. Because this was such a large conference with such a broad range, I am going to divide up my post thematically: Social Media, Sessions and Public  Events.


Well before the start of the conference, the organisers of the iCHSTM were dedicated to giving it a strong presence in social media. This can only be a good thing with the way that social media and academia seem to be joining up, especially in the blogosphere and on Twitter. First, the iCHSTM organisers have had a conference blog running since May. This began with select presenters offering brief descriptions of the papers they were to present, and evolved to include a daily “Congress Transmission” that provided summaries of the previous day’s events and any updates to the day’s program.

There is a conference Flickr page, updated as the conference progressed, that will give readers a glimpse of everything that was going on (and if you look carefully you may see your intrepid reporter in there somewhere).

For those who missed the conference–or even conference attendees who want to catch something again–there is a iCHSTM Youtube page, which has videos of many public events, including some great comedy bits from the Bright Club night.

The iCHSTM has a very active Twitter page and dedicated hashtags for the conference (#iCHSTM #histsci #histech #histmed). These were great resources for finding out the latest news and changes, as well as for following the livetweeting of sessions throughout the conference.

The number of sessions and presenters at the conference was impressive: nearly 1400 presenters in 411 sessions, according to the website. The topics ranged from ancient astrology to asbestos in 1940s Quebec. As a result, it is impossible to do justice to the sheer breadth and variety of papers that were given in Manchester. Here is a sampling…

In a session that I chaired, “Spaces and Practical Knowledge”, Anita Guerrini of Oregon State University discussed “The Ghastly Kitchen”. The early modern kitchen, she argued, was a site of life science, namely, dissection. It was an ideal place for conducting scientific experiments, being where instruments for dissection were kept and the cooking of animal parts occured. As well, senses such as taste and smell were important in discovering the properties of objects. Audio of her paper can be found, along with that of other iCHSTM bloggers, here.

In a session on “Geology and Literature”, Gowan Dawson (University of Leicester) spoke on “Dickens, Dinosaurs and Design”, comparing the harmony of Charles Dickens’s serialised novels with the perceived harmony and order of dinosaur skeletons. Dawson looked at the language used by both Dickens and his friend Richard Owen, a comparative anatomist. Dawson suggested that Dickens drew on the procedure and terminology that Owen used for the preparation of skeletons for display. Although the work of these two men may seem miles apart, both men wanted to bring about a similar harmony in their work, or a “fusing together” of vertebrae and chapters.

In the same session, Stephen M. Rowland (University of Nevada Las Vegas) examined “Mark Twain and Historical Sciences”. Twain wrote about science throughout his career (such as Paleontology in 1871 and Life on the Mississippi in 1883), and also interjected scientific remarks into his fiction works like Tom Sawyer. Rowland presented a number of examples from Twain’s prolific career, arguing that Twain followed scientific developments. Although Twain’s early works poked fun at new ideas and reflected contemporary American skepticism, Twain later used the respectability of science to argue against religious fundamentalism and Biblical literalism.

Janine Rogers (Mount Allison University) combined two of my favourite things– codicology and museums–in “The Medieval Codex and Early Science Collections and Museums”. She argued that there is a connection between the medieval codex and its focus on ordinatio and compilatio and early collections and museums. Compilatio viewed the compiler of the medieval book as God’s editor; thus, the book was a mirror of the universe. It was tied to the idea of unio, a union of all knowledge. Similarly, ordinatio, the placement of texts and images on the page, was a theological activity. Even the grotesque marginal imagery served to discuss or critique the main text. Rogers contends there was a similar adherence in early science collections and museums to the idea of knowledge be all-encompassing. The ideal museum, particularly in Victorian architecture, mirrored the layout of the ideal manuscript page, enclosing all knowledge within its walls.

Constance Putnam delivered a fascinating paper on the practice of rural medicine in the mid-twentieth century and the acquisition of medical knowledge by those not formally trained (“Knowledge-making in a rural general practice in mid twentieth-century America). Putnam’s research drew on the archive of thousands of her mothers’ letters. Her mother was not formally trained in medicine, but worked for decades as a laboratory technician and medical assistant with her husband in rural New England. Putnam’s archive demonstrates that the role of wives working in unofficial capacities was necessary for a rural medical practice to succeed.


iCHSTM also included a number of excursions to introduce attendees to Manchester and its involvement in the history of science, and public events to engage the wider population. These events included a tour of the Old Trafford, historical tours of Manchester, an Alan Turing opera, a Victorian séance event, a beer festival, and several musical performances.

One of the most…explosive was the Victorian Science Spectacular. This was presented as a demonstration of Victorian science in the 1890s. Four presenters: Aileen Fyfe as Miss Ann Veronica Stanley, a learned scientific gentlewoman; Katy Price as Mr. George Wells, inventor and brother of H.G.; Iwan Rhys Morus as Professor Marmaduke Salt of the Royal Panopticon of Popular Science; and Tim Cockerill as Mr Selwyn, chemical conjuror and assistant to Professor Salt took turns to present their apparatus to the audience. The demonstration consisted of experiments involving electricity, such as telegraphy and Jacob’s ladders, and demonstrations of the latest magic lanterns and cinematographs. With a few exceptions they used authentic period pieces. This was a fascinating look into the kinds of experiments that were used in the public scientific demonstrations of the nineteenth century, and how they blended entertainment with education. The question period following brought up a number of questions about the reaction of contemporary audiences, the practicalities of transporting the apparatus, and how this presentation has been used to engage the public with the history of science.

James Sumner subjects an innocent pint of beer to suspicious looking chemicals.

One of the highlights of the conference was James Sumner’s talk “Chemists, brewers and beer-doctors”, given in the local pub on Wednesday night. Sumner, co-organiser of the Congress, gave a demonstration of the chemical changes that unscrupulous “beer-doctors” performed on beer in the eighteenth and nineteenth centuries. With the price of malt dependent on the harvest, it became difficult to make a profit during the years of bad harvests. Thus, brewers turned to chemicals and science to turn a watered down pint into something indistinguishable from its full-powered brethren. Sumner subjected a pint of beer to many of the same chemicals that were used by these brewers, including innocuous substances like caramel colouring and vinegar. However, he refrained from the more dangerous substances like the metals that were used to give the impression of drunkenness (and which could lead to death in the wrong amounts). If this topic interests you be sure to check out Sumner’s new book, Brewing Science, Technology and Print, 1700-1880, which has just come out from Pickering & Chatto.

iCHSTM held a Bright Club comedy night following Sumner’s beer presentation, with five brave academics performing sets. This was a fun evening with a lot of great humour. Who knew that asbestos could be funny? All of the routines from the evening are online at the iCHSTM’s Youtube page so you don’t have to take my word for the quality, you can see for yourself.

The next congress will be held in the summer of 2017 in Rio de Janeiro, so keep an eye out if you want to catch this great conference the next time around.

Medieval Fertility and Pregnancy Tests

By Catherine Rider

Tests are a familiar part of modern pregnancy.  There are tests to show if a woman is pregnant and track the progress of the pregnancy, often revealing in the process whether she is expecting a boy or a girl.  If a woman does not conceive after several months of unprotected sex, there are also tests which aim to find out if anything is wrong.  These tests are based on modern technological advances and medical understandings of how the body works, but the desire to understand, predict and test matters concerning pregnancy and fertility is not new and tests for many of the same purposes appear frequently in medieval and early modern recipe books.

Recipe books contain numerous tests to show whether a pregnant woman is expecting a boy or a girl – for example, place a drop of milk from her breasts in water, and if it sinks then the child is a boy, but if it floats, the child is a girl.[1]  However, the majority of tests were for when pregnancy did not happen.  They claimed to tell the reader whether a woman could conceive, or whether the ‘fault’ lay with the man or the woman.   The most popular was a test that had to be performed by both partners.  As one anonymous fifteenth-century English recipe collection explained:

Knowing the default of conception, whether it belong to the man or the woman. Take two new earthen pots, each by itself; and let the woman make water in the one, and the man in the other; and put in each of them a quantity of wheat-bran, and not too much, that it be not thick, but be liquid or running; and mark well the pots for identification, and let them stand ten days and ten nights, and thou shalt see in the water that is in default small live worms; and if there appear no worms in either water, then they be likely to have children in process of time when God will.[2]

This test had a long history.  It can be found as early as the twelfth century, in a southern Italian gynaecological treatise that was attributed to a female physician named Trota.[3]  Along with other fertility tests, it continued to appear in medical textbooks throughout the Middle Ages and into the early modern period, and was often copied into recipe books.

I’m interested in what this and similar fertility tests can tell us about medieval understandings of infertility.  For example, the bran-and-urine test shows medieval and early modern medicine recognised that men as well as women could be infertile.  This was certainly true in longer, more academic medical texts which often contained numerous recipes for medicines to cure infertility in either sex. In the recipe books, remedies for male infertility are much rarer, but the fertility tests show that many recipe collectors acknowledged it as a possibility – in theory at least.

But how exactly were these tests intended to be used?  It is very difficult to know.  The recipe collections do not tell us who used these tests, or under what circumstances, or even if they were used at all.  So far I haven’t found any references to them in other sources that might shed light on these questions.  In theory it is possible that they were used to test the fertility of a prospective husband or wife before marriage.  This would be an attractive (and logical!) idea because in pre-modern society having children was important for both men and women, but infertility was not recognised as a ground for divorce.  Once you were married to an infertile partner, you were stuck with him or her.  However, if the tests were used in this way it has left no trace in the sources.

Another possibility is suggested by the last line of the recipe: ‘if there appear no worms in either water, then they be likely to have children in process of time when God will.’ An alternative version of the same recipe, copied in the fifteenth century by an educated layman named Robert Thornton, gave a different interpretation: if no worms appeared in the water, ‘then may men help them to have children with medicines.’[4]  It was possible that the test would show neither partner to be infertile. In these cases, the tests may have been designed not primarily to lay blame, but to offer reassurance that conception was possible and that the couple would conceive in time. It was worthwhile seeking medical treatment or praying in the hope of attracting God’s favour.

A final reason why pregnancy and fertility tests may have been so popular in medieval and early modern recipe books is perhaps the simplest of all.  They promised clear answers about the mysteries of conception and pregnancy for men and women going through a process which was – and still is – fraught with as much uncertainty and anxiety as excitement.

Exploring CPP 10a214: The Elusive Compiler

By Rebecca Laroche with Hillary Nunn

Up until now, Hillary Nunn and I have been conducting our explorations (20/06/2013, 21/05/2013, 09/04/2013, 12/03/2013, 20/02/2013) under the working hypothesis that one of the compilers of the College of Physicians manuscript 10a214 was a mid-17th century divine named Calybute Downing (1606–1644).  This hypothesis mainly grew from a simple phrase “probatum per me Cal. Downing” (24) at the end of one of the early recipes in the collection and the inclusion of many recipes attributed to one Elizabeth Downing, the name of Calybute’s mother. There was also a reference to Hackney (20/06/2013), where Downing was once minister.  A recent all-too-brief research trip to London has complicated this hypothesis and raised several questions…

With our working hypothesis in mind, I conducted a preliminary search in the online catalogs for autograph evidence of Calybute Downing and was excited to find that the British Library did indeed hold a letter from the minister to a Mrs Barkley.[1] With only two days for library research, I immediately called up the collection in which it was held–and was thankful to find it available.

Imagine my anticipation of its arrival from the vault.  Imagine my disappointment when neither hand (the signature being different than the body) in the letter, which was an extended assurance of grace from a minister to one of the faithful in doubt, matched the hand of the Downing recipes in the manuscript.

A few scholars of recipes may recognize this disappointment.  Many a mention of historically significant figures are confounded by the presence of secretaries and the accommodation of one collection of recipes into another through copying and gifting.[2]  I have come up with two possibilities (and would welcome other suggestions) that explain these non-matching hands:

  1. The Calybute Downing of the recipes is not the divine, but instead his father of the same name, who would have been married to Elizabeth and who was alive in 1640, the one date in the manuscript.  This hypothesis could mean an earlier compilation, but would face some difficulties in explaining the Hackney reference.
  2. The recipe book and the letter could have been compiled by two different secretaries. The Downing signature in the letter is markedly different than the body, which is a very difficult secretary hand, whereas the recipe book is in an incredibly clear italic.If the Downing recipes were copied out in anticipation of making them a gift for use, their relative legibility would be essential. As a correspondence to be considered closely and slowly, the letter’s cramped hand would not be as much of an issue.

Clearly, as I write this, I am becoming more convinced of the second hypothesis, but:

  • if Calybute Downing was prone to hiring secretaries, in whose hand were the original recipes that the secretary then copied out?
  • was the original manuscript made by Elizabeth herself, or by yet another member of the household?

Given the proximity of some of the entries to print sources (18/10/2012, 21/05/2013), it seems unlikely that all of these were transmitted orally. However, the inclusion of a “by me” in the recipes implies Calybute’s presence, if not in the immediate transcription, at least in one of the earlier written record of the recipes.

Obviously, further research is needed!

Smelling ‘Violet’ in Renaissance Works

By Colleen Kennedy

The violet (Viola odorata) is cited in several herbals and many recipe books as a particularly sweet scented, fragrant flower. Herbals, such as Culpeper’s, describe the violet as a “cold and moist” plant, with many medicinal qualities. It is used as a laxative, and as a treatment of syphilis and uterine complaints; it counterbalances choleric humors, is good for many lung ailments, eases headaches and sleeplessness, and is a general panacea.

Violets are also commonly used in recipes, either as “cakes of violet,” “candied violets,” “conserve of violets,” or “syrup of violets,” as flavoring for metheglins (meads), and to add aromatic qualities to vinegars and other recipes:

To Make Syrup of Flowers:

Take of Violet flowers fresh and pickt, a pound, clear water boiling one quart, shut them up close together in a new glazed pot a whole day, then press them hard out, and in two pound of the Liquor, dissolve four pound and three ounces of white Sugar, take away the scum, and so make it into a Syrup without boiling. (Woolley 6)

Any of Hannah Woolley’s recipe books are a good place to begin to study early modern recipes utilizing violet flowers. Violet’s pleasant odor is also the source of its medicinal powers and cause for its common domestic usage.

Hannah Woolley's The Accomplish'd lady's delight in preserving, physick, beautifying, and cookery (1675)

So, what does the violet smell like?  English, alas, lacks a smell-vocabulary, and violet is repeatedly only listed as “sweet” or “fragrant.” Avery Gilbert considers the two distinct “voices” available to modern perfume makers: “Ingredient Voice” (the actual list of and proportions of ingredients) and “Imagery Voice” (“atmospherics, the drama of seduction, passion, and mystery”) (15). It is in that latter voice that we move closer to the more detailed early modern accounts of the aroma of violet.

For example, modern perfume blogger Normand Cardella, in his review of Yves Saint Laurent’s Paris, muses on the smell of violet: “So… what does a violet note smell like?  Well… it’s powdery, a little sweet and decidedly sad.  Musically, a violet note in perfume would be a minor chord.”

Likewise, for early modern writers, the violet is also a sad  and musical aroma. Francis Bacon, in his essay “Of Gardens” (1625),  links pleasurable odors and sounds (and much earlier than our modern perfumers): “And because the breath of flowers is far sweeter in the air (where it comes and goes like the warbling of music) than in the hand, therefore nothing is more fit for that delight than to know what be the flowers and plants that do best perfume the air”. Violet is his favorite perfumed flower: “that which above all others yields the sweetest smell in the air is the violet”.

The violet’s “imagery voice” is most fully articulated in Duke Orsino’s opening lines of Twelfth Night:

“Orsino and Viola” by Frederick Richard Pickersgill (c. 1850)

“If music be the food of love, play on.

Give me excess of it that, surfeiting

The appetite may sicken and so die.

That strain again, it had a dying fall.

O, it came so o’er my ear like the sweet sound

That breathes upon a bank of violets,

Stealing and giving odour. Enough, no more.

‘Tis not so sweet as it was before.” (1.1.1-8)

Much of the language here that applies to music or love is equally applicable to the sensation of smelling violets,  especially violet’s unique chemical compound and its effect on the sense of smell. As Diane Ackerman describes: “Violets contain ionine, which short-circuits our sense of smell. The flower continues to exude its fragrance, but we lose the ability to smell it. Wait a minute or two, and its smell will blare again. Then it will fade again, and so on.”

The discovery of its isomer ketones did not occur until the late nineteenth century, yet, its affects were all very real experiences for early modern writers, such as Shakespeare, who attempt to distil and capture the essence of violet in distinctly beautiful terms, with the violet “stealing and giving odours.”

The “dying fall” of Orsino’s sad tune is like the melancholy aspects of the violet, evoking impermanence, transience, and death. Even Orsino’s command to stop the music can also describe the anesthetic properties of ionine.  As Orsino complains though, the scent, the song, the sensations, and so on is “not so sweet as it was before.”

John Gerard's "The herball or Generall historie of plantes" (1633) Chapter 312: Of Violets
John Gerard’s The Herball or Generall Historie of Plantes. (1633) Chapter 312: Of Violets

Orsino’s very mind, in its melancholic state, is affected by sweet airs—whether sad songs or fragrant violets. As the early modern brain was believed to be acutely affected by odors, and the violet emits a particularly sweet and sad aroma, the botanist and herbalist John Gerard’s regard for the violet’s olfactive and affective properties should not be surprising:

[Violets] haue a great prerogative aboue others, not onely because the minde conceiveth a certaine pleasure and recreation by smelling and handling of those most odoriferous flours, but also for that very many by these Violets receive ornament and comely grace …And the recreation of the minde which is taken hereby, cannot be but very good and honest: for they admonish and stir up a man to that which is comely and honest… do bring to a liberall and gentle manly minde, the remembrance of honestie, comelinesse, and all kindes of vertues. (Chapter 312: “Of Violets” 849-850)

Gerard nicely summarizes the memorable, virtuous, affective, symbolic, and olfactive properties of the violet that we have been sniffing out in this brief essay.
