Making Senses: Artisanal Practice and Sensory Perception in an Early Modern French Manuscript

By Tillmann Taape

Ms Fr. 640 was written in French by an unknown craftsperson in Toulouse, likely between 1580 and 1600. [1] It is an intriguing and eclectic source, with entries ranging from medical recipes to metalwork and pigment-making, and it forms the core of the Making and Knowing Project at Columbia University, introduced previously on the Recipes Blog in a post by our Director, Pamela Smith.

With its numerous instructions for making things, our manuscript provides a rich case study for the way artisans worked with and thought about materials. As previous posts in this series on Recipes and the Senses have shown, physicians, alchemists, apothecaries, and other craftsmen recognised in their bodies and its senses an important set of tools for understanding and manipulating the material world, and historians pay increasing attention to these embodied and sensory ways of knowing. In this post, I will share a few examples of the rich language of the senses in Ms. Fr. 640. As one might expect from a manuscript including painting and sculpture, the eye often takes precedence over the other senses. However, a discussion of the visual in the manuscript would by itself be far beyond the scope of a single post – we spent much of this year just trying to figure out how the author-practitioner conceptualises different pigments and shades of blue. The aim here, therefore, is to focus on the oft-neglected non-visual senses and what they can teach us about our author-practitioner’s concept of the material world, his ‘material imaginary’.


A strong smell was often a sign that things had gone wrong – the papier-mâché had turned rotten while being left to soak, or a kitchen pot had been made with too much latten (a copper alloy), which ‘stinks and smells bad’ (fol. 36v). However, smells could also help identify the materials needed for a recipe. The ingredient list for a metal alloy, for example, includes the intriguingly specific ‘congealed mercury with the smell of tin’ (fol. 92v). Musing on one of his favourite topics, the properties of fine sand used for metal casting, the author-practitioner notes that

white sand smells like sulphur when heated, and I believe it would melt. And as the substance has been cast in it, it acquires in the mold a lustre as if it were leaded or vitrified. I believe that glassmakers could use it (fol. 99r).

In addition to his observation of a vitreous glaze on the cast object, it is the sulphurous smell which suggests to the author-practitioner that this particular kind of sand is prone to melt and could even be used for making glass. Throughout the manuscript, sulphur does indeed appear as a material which can easily be melted and used to cast small objects, and even appears to function as a sort of material metaphor for transformation and experimentation.


The sense of hearing becomes itself the subject of a short entry. Under the heading ‘hearing from afar’, the author-practitioner records one of the tidbits of advice and tricks for daily life which are scattered here and there throughout the manuscript: ‘Make a small hole in the ground, put your ear against it during the night or during a quiet time, and you will easily hear muffled sounds’ (fol. 125r). In addition to facilitating amateur espionage, specific noises could serve as helpful indicators in the workshop. Before casting metal into a mould made from cuttlefish bone, the author-practitioner writes, one has to make sure that it is completely dry: ‘you will know that they are dry enough when, after having held them near the fire a little, their inside and the impression scream & crackle when you hold them up to your ear’ (fol. 145r). If one was prepared to listen carefully, the materials themselves could tell when they were ready to be worked upon.

The sense of taste could also help to assess and adjust one’s materials. To make ‘essence of sal ammoniac’, for example, ‘the size of two chestnuts of pulverized sal ammoniac suffices in a pot of water, and to the tongue you find the water moderately salty, for too much is not good’ (fol. 111v). The concentration of the sal ammoniac solution was clearly of some importance here, and like in most early modern recipes, the given measurements – size of a chestnut, a pot of water – might not yield very consistent results, so a qualitative sensory indication – ‘moderately salty’ – is added as a further point of reference. As well as checking one’s own procedures, taste could of course be used to assess the quality of merchandise. The city of Toulouse, where our manuscript was compiled, gained much of its considerable wealth from the trade in woad, a blue dyestuff whose French name, pastel, is a likely origin of the term ‘pastel’ colours in English and other European languages. It is not surprising, therefore, that the author-practitioner mentions this sought-after material and tells us how to tell the good from the bad. This involves several steps, including inspection and a dyeing test, but the first step is a taste test: ‘The goodness of the woad is known when, put in the mouth, it gives a taste as of vinegar’ (fol. 39r).


Perhaps unsurprisingly for someone who clearly worked with his hands a lot, the sense of touch plays a particularly important and intriguing part in the author-practitioner’s practice and writing. Returning to his favourite topic – the different kinds of sand or plaster used for casting moulds – he describes how the addition of a substance called alum de plume (literally ‘feather alum’ – it probably refers to a group of minerals known as feldspars in English) helps the mould hold together because it forms fibrous structures (hence probably the reference to feathers). Its production requires a complex process of heating and grinding up in a mortar. In the margin next to the recipe, the author-practitioner notes that one should grind the alum slowly and in small portions, and finally ‘render it very fine & soft to the touch’ (fol. 108v). The manuscript is full of these kinds of haptic properties to indicate the appropriate consistency or particle size of materials. Another ‘sand’ for casting, for example, is made with ‘the bone of oxen feet, very burned & pulverized & ground on porphyry, until it is not felt between your fingers’ (fol. 84v). Intriguingly, here the reader is told to stop grinding not when they can feel a particular sensation, but when they can no longer feel the material at all with their fingers.

As it turns out, this criterion of eluding the sense of touch was an important technical concept for early modern artisans. Our former Making and Knowing postdoc Jenny Boulboullé and former students, Raymond Carlson and Jordan Katz, have shown that the term impalpable, that is to say ‘un-feelable’ or ‘impalpable’, is central to the way the author practitioner experiences and thinks about different kinds of materials used for casting moulds.[2] Furthermore, they found that he is not the only one: the use of the term ‘impalpable’ is used in published works on metallurgy, such well-known book Pirotechnia by the sixteenth-century Italian founder and metallurgist Vanoccio Biringuccio, and the Secreti, a famous book of secrets attributed to Alessio Piemontese. In his emphasis on the haptic sensation of a material being impalpable, then, the author-practitioner speaks to a sensory terminology apparently widely shared by expert makers.

Describing specific sensory experiences can be difficult, and it makes sense to refer to well-known parallels from daily life – a smell like sulphur, a taste like vinegar, and so on. When it comes to the sense of touch, too, the author-practitioner relates processes described in his recipes to everyday practices. As our former student Emma Le Pouésard has shown, the practices surrounding making bread were a particularly fruitful source of these kinds of comparisons.[3] To unmould a cast object, one should ‘strongly separate the moulds as if you wanted to tear bread apart’ (fol. 114v). In an age before thermostats, this could even provide a way of gauging consistent temperatures. For one’s domestic taxidermy needs, the author-practitioner writes, one could dry animals ‘in an oven as warm as when bread has been taken out’ (fol. 129v). In a recipe for making stucco, bread making is used as a referent for working up the right kind of consistency: the recipe tells us to ‘knead as if you wanted to make bread’, until the stucco paste is ‘firm as bread dough that is ready for the oven’ (fol. 29r).

When we tried making stucco in the Making and Knowing Lab in the Fall semester, this proved to be very useful guidance. While we were not experienced bakers in the way that many early modern householders probably were, we could draw on our experience from one of our ‘skillbuilding’ exercises a few weeks earlier, when we made bread to use as a mould for wax casting, replicating one of the most intriguing processes in the manuscript. When it came to making stucco and mixing the right amounts of tragacanth gum and rye flour or champagne chalk, the author-practitioner’s instructions about kneading to a consistency like bread dough were very useful, especially in the absence of any other indication of measurements. By adding flour until we achieved a dough-like mass which would ‘stretch enough without breaking’ (fol. 29r), we eventually produced stucco which displayed fine detail and could be detached from the mould without too much trouble.

Even this brief tour of Ms. Fr. 640 shows that much is to be gained by paying attention to the non-visual senses in recipes and practical instructions. In the absence of precise standardised measurements and procedures, sensory descriptions were paramount to articulating a material’s properties, whether it was of good quality, or how much longer it needed to dry, boil, soak, or be crushed in a mortar.

Tales from the Archives: Smelling ‘Violet’ in Renaissance Works

In 2017, The Recipes Project celebrated its fifth birthday. We now have nearly 650 posts in our archives and over 160 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.

This month’s we re-feature a post by Colleen Kennedy, first published in August 2013. I think that it fits very well with our conversations this month, don’t you?

Enjoy the spring flowers, everyone!



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)
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.

Roman Recipes and the Senses

By Erica Rowan

We do not have many recipes from the ancient world and certainly none presented in the user-friendly format found in today’s cookbooks with precise measurements, cooking times and images of the finished product. Some ancient recipes are found at the end of agrarian handbooks, like those produced by Cato the Elder (234-149 BC) (for more see Catherine Draycott’s post https://recipes.hypotheses.org/5005), while others are described as part of a philosophical dinner party (Athenaeus’ Deipnosophistae). The most famous recipe book, and the one which most reconstructed Roman recipes are based, is Apicius’ De re coquinaria or On the subject of cooking. Compiled sometime during the 4th century AD and named after an infamous 1st century AD cook, it contains recipes for vegetables, pulses, meat, seafood and game. Ingredients are listed in the text along with rough instructions for the preparation and cooking of the dish (think instructions for the technical challenge in The Great British Bake Off). The lack of ingredient quantities suggests that it functioned as part coffee table book and part chef’s manual, whereby the cook already had a good understanding of ingredient combinations and quantities. In other words, it was not for the beginner home cook.

Despite a lack of precision and clarity in these surviving recipes, it is possible to gain a detailed understanding of the sensory experience involved in the preparation and consumption of these dishes. This is due to the survival of several pieces of Roman kitchen equipment and at times, the food remains themselves. At sites like Pompeii and Herculaneum (Italy), which were destroyed by the eruption of Vesuvius in AD79, we not only have cooking pots, plates and serving dishes, but also the remains of the kitchens and dining rooms where the food was prepared and eaten.

So what was it like to make and eat Roman food? Let’s look at one of Apicius’ recipes in detail.

Lentils with mussels: take a clean pan, (put the lentils in and cook them). Put in a mortar pepper, cumin, coriander seed, mint, rue, pennyroyal, and pound them. Pour on vinegar, add honey, liquamen, and defrutum, flavour with vinegar. Empty the mortar into the pan. Pound cooked mussels, put them in and bring to heat; when it is simmering well, thicken. Pour green oil over it in the serving dish.

[Apicius, On the subject of cooking, 5.2.1, from Grocock and Grainger 2006: 209]

The first thing you may notice about this dish is the vast number of flavours and seasonings involved. In addition to the various herbs, the recipe also calls for liquamen, a fermented fish sauce similar to the Thai fish sauce Nam Pla, and defrutum, concentrated grape syrup made from boiled down grape juice. Roman dishes are notorious for their seemingly strange and startling mix of flavours. However, before we get to the taste, let’s start with sensory experience of preparing this dish.

Firstly, let’s assume that this dish is being prepared for a dinner party in a wealthy Roman household. If you were the one making the food you would have been a slave, working in a hot, small, smoky kitchen. Roman kitchens are readily identifiable by their large ceramic hearths. Cooking took place on the hearth; the space beneath is just for the storage of fuel, usually charcoal or wood. The lack of chimneys in Roman kitchens means that there was poor ventilation and the smell of the cooking food would have been quite strong. The small size of most kitchens, even in larger houses, meant that the room would have been hot, even in the winter.

At least two pieces of cooking equipment are required to make this recipe, a pan and a mortar. The mortar would have been a mortarium (image), a large shallow ceramic bowl with stone inclusions in the bottom to provide a rough grating surface. All the seasonings would have been ground by hand using a mortarium and wooden pestle. The pan (perhaps made of bronze) would have been placed on a metal or ceramic tripod with charcoal underneath. The varying materials of the mortarium, pestle and pan would have made the tactile experience quite dynamic. Once the dish was finished, depending upon the wealth of your owners, you would have poured the finished product onto a ceramic, bronze or silver platter. You’d then promptly move on to preparing another dish as Roman dinners usually consisted of several courses.

Now let’s shift gears and say you’re a guest at the dinner party and you have the opportunity to taste and smell this dish. The combination of flavours in this recipe, and particularly the mixture of the liquamen, defrutum, honey and vinegar would have given it a sweet and salty taste. In my experience, having made several Roman dishes, the flavour combination is strange but not jarring or unpleasant. Roman food tasted much more like modern Thai or Chinese cuisine than modern Italian with its frequent combination of sweet, sour, and salty. The black pepper in the dish, imported from India, would have provided a hint of wealth and exoticism as it was by far one of the most expensive and foreign seasonings you could use at this time. If you had grown up consuming a Roman diet then this dish would have smelled and tasted very normal to you. The herbs, in addition to appearing in numerous other Apician recipes, are also frequently mentioned by other ancient authors, suggesting that they formed an important part of the Roman diet. This importance is confirmed by the recovery of many of the herbs, and in particular coriander, at sites throughout the Roman Empire.

The military and merchants carried and imported these herbs to all the corners of the Empire, perhaps to evoke a taste of home. Some individuals native to the northern provinces, such as Gaul and Britain, adopted these seasonings into their local cuisines. In addition to probably enjoying the taste, they used them to display their wealth or allegiance to Rome.

In sum, there is much sensory information that can be gleaned from Roman recipes and the archaeological remains of food preparation and consumption. What is perhaps most striking is the vastly different interactions and experiences of those in the kitchen compared to those in the dining room!

Gershom Bulkeley (1635-1713): A Sensory Chymist in Colonial Connecticut

By Donna Bilak

Who was Gershom Bulkeley? (you may well ask). A Harvard-educated Puritan gentleman from an important New England family, Bulkeley spent most of his life in Connecticut as a colonial divine, physician, and magistrate of upstanding (and by contemporary accounts obstinate) character. Bulkeley was also an iatrochymist – an aspect of his work that is only now starting to receive scholarly attention – and prolific compiler of notes about the medico-alchemical experiments that he conducted in his laboratory, likely a part of his dwelling place.

About 25 miles from where Bulkeley once lived, there now exists a kind of biblio-bunker in the University of Connecticut Health Center. This is where the Hartford Medical Historical Society Library keeps its collection of rare books and manuscripts. And this is where twenty-four manuscripts that are either by or associated with Bulkeley ended up. NB: there is treasure buried in this underground archive! (I am sure that as a Puritan with millenarian expectations, Gershom himself would be comforted to know that in the event of some kind of apocalyptic event, his notebooks will survive intact.)

I came across this cache back in 2011 while chasing down different leads for my dissertation about one of Bulkeley’s contemporaries, another Harvard-trained Puritan minister-physician-alchemist named John Allin (1623-1683). But in going through the various manuscripts, I was drawn to one of Bulkeley’s notebooks in particular: Bulkeley MS 5.

FIG 01 shows the spine of the 19th-century book cover (constructed of boards covered with period cloth of a by now indeterminate greenish-blue color), the spine bears the imprint “Parley’s Fables 1834” in faded gold letting.

(author’s own photograph)

This is a small book that has been rebound using the cover from a 19th-century book of fairy tales, and it contains a series of entries about alchemical experiments that Bulkeley undertook between 1703 and 1706 scrawled across eight pages, with an additional sixty-three pages oriented upside down at the back of the book of more extensive laboratory notes of ongoing experiments, dated 1702 to 1707. At some point in time, both sets of notes were bound together with Bulkeley’s (undated) abridged copy of the Institutiones medicae by Lazare Rivière (1589-1655) – i.e., two hundred and forty-four densely written pages of Latin in a neat and minute hand ­– sandwiched between the aforementioned two sets of laboratory records. Intriguing stuff…

…because Bulkeley crammed this notebook full of particulars about chymical substances, instrumentation, and techniques. Bulkeley worked with different chymical substances for pharmaceutical production. His recorded experiments are filled with actions (tasting, weighing, drying, stirring, observing, waiting), and his laboratory entries document a range of output (he made salts, spirits, powders, pills, oils, dissolvents, elixirs). In their preparations, Bulkeley worked with iron, copper, and antimonial substances, as well as mercury, arsenic, silver, coral, and turpentine, and he used various chymical processes (calcination, coagulation, sublimation, evaporation, distillation). Bulkeley also detailed the equipment he used, describing things like various retorts (one is silver) and curcurbits (a glass one, a silver one), heavy and light scales, a blue jug, a copper vessel, an alembic, a receiver.

Another striking feature of this notebook is Bulkeley’s use of naked senses – taste, touch, and sight – as tools of investigation in his experiments. Bulkeley describes the consistency of experimental matter in comparison to common foodstuffs (“pudding” features large in his notes as a standard for assessing viscosity). Bulkeley also records the presence, or absence, of “lixiviate”, “vinegar”, “alcalisate”, or “urinous” tastes; interestingly, these references to tasting generally occur (when they do) at the conclusion of a given entry. Bulkeley’s haptic perception in the lab comes across in three entries, which record experiments that took place between January 27 and February 1, 1702. Here, Bulkeley detailed a distillation process involving nitre, mineral iron, and oil of vitriol (the objective appeared to be the production of aqua fortis), whereby an outcome of these distillation experiments was to harvest the caput mortuum.

Bulkeley observed that the dregs from January 27th “looked pretty white,” while that from January 29th was reddish, and he concluded with the comment, “Both the Cap. mort came out easily enough & crumbly but the 2d was not so soft & easy as the first/”. This seems to indicate mixed results in Bulkeley’s estimation. A third (and likely final) entry dated February 1 indicates the continuation of this experiment, with some changes in ingredients (i.e., the addition of flowers of sulphur) and procedure (Bulkeley undertook the sublimation of the matter in question). Notably, Bulkeley recorded that he did not lute his receiver (meaning that he did not undertake the preventative measure of smearing a claylike compound around this vessel to seal and thusly protect it in heating procedures).

This time, things did not go so well with the experiment:

I could not get no more off the broken pot: & flowers in the head that I could save, [6…] : that is in all. But it was the same pitcher in which I had destilled A. F. put in before, suc. Janr 27. & 29. & now it was cracked & had leaked a little out into the sand, had drunke up some into it; & I could not get the Cap. mort cleane off, nor the flowers absolutely cleane: & tis very Pbable some might evaporate, the Rec. not being luted on./ The sulphur in the Capt Mort was not fixt, but which upon a coale readily smoake & flame burne with a very fine blew flame./

FIG 03 LH page: Feb.1, 1702 caput mortuum experiment entry (goes with my transcription) (author’s own photograph)

These entries about the caput mortuum show Bulkeley’s bodily way of knowing as a form of assay, a testing procedure that links sensory analysis with chemical analysis in his evaluation of the progress of his work. This also shows that Bulkeley paid just as much attention to detailed sensory descriptions of his failures in the lab as he did to successes.

Bulkeley MS 5 is a valuable artifact of Bulkeley’s heuristic laboratory methods in the production of chemical pharmaceuticals, likely destined for use in his medical practice. While this notebook presents us with puzzles (what prompted its compilation? how was it used?), at the same time we are granted open access into Bulkeley’s experimental activities, a window into his dynamic medico-alchemical operations in a colonial community at the turn of the 18th century.
