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.

A forgotten chapter in natural history: the taxidermy of man

By Marieke Hendriksen

Having written a book on eighteenth-century anatomical collections, I know a thing or two about historical techniques for preserving (parts of) the human body. As I am interested in natural history collections more generally, I also did some research on the preservation of animal bodies, and even took a taxidermy course myself. However, recently I realised that the preservation of human and animal bodies were historically even closer connected than I had imagined. Yet ideas about which parts of the human body could and should be preserved, and how, diverged greatly, particularly when it comes to skin, or taxidermy. Taxidermy, from the Greek τάξις (taxis) and  δέρμα (derma – I am adding those for people who may not read Greek script), literally means ‘the arranging of skin’.

Fragment of an engraving of the anatomical theatre of Leiden University, early 17th century, showing visitors who appear to discuss a human skin. Contemporary engraving by Willem Swanenburgh; drawing by Jan van ‘t Woudt (Johannes Woudanus).

There are a few known cases of attempts to preserve human skins in their entirety before 1800 – for example, there was a human skin in the Leiden anatomical theatre in the seventeenth century – but that wasn’t stuffed, and such attempts appear to have been altogether unsuccessful. If human skin was preserved, it was mostly small pieces, which were used to study things like skin colour and structure, tattoos, or pathologies. By the end of the eighteenth century, the preservation of an entire human skin in a lifelike pose was of little interest to anatomists. Normal internal anatomy would be studied through dissection and the creation of preparations and skeletons, and pathologies of the skin could be preserved by making preparations of small sections of skin. As healthy skin can be studied perfectly easily in live subjects, there was little reason to pursue the taxidermy of man. This is reflected in anatomical handbooks like Thomas Pole’s 1790 Anatomical Instructor (reprinted in 1813), which gave detailed directions for numerous methods to preserve parts of the human and animal body, including entire heads and foetuses, but did not say anything about how to preserve only skin. On the contrary, Pole advised to remove the cuticle from a head that was to be preserved,  as this would give ‘a brightness to the complexion’.[1]

However, with the growing popularity of taxidermy – the mounting of animal skins in lifelike poses – and the rise of physical anthropology in the early nineteenth century, there were a number of experiments with human taxidermy, the most famous of which was probably Jeremy Bentham’s unsuccessful attempt to have his body made into an ‘auto-icon’ after this death. Then there was ‘el negro’ or ‘the negro of Banyoles’, whose faith was described by Dutch author Frank Westerman in his 2004 book El Negro en ik (‘El negro and I’). The remains of this young African San man were stuffed by two taxidermists, the French Verreaux brothers, in the 1830s, and remained on display in a local Museum in Banyoles, Spain, until 1997. Eventually his remains were send for burial in Botswana in 2000. Jules Pierre (1807-1837) and Jean Baptiste Édouard (1810-1868) Verreaux created taxidermy specimens of exotic animals for their father’s Parisian shop in natural historical objects, Maison Verreaux, and, as ‘el negro’ shows, used human bones for his models.

For a long time, ‘el negro’ was the only known case of nineteenth-century human taxidermy. However, a recent discovery suggests that the Verreaux brothers used human remains more frequently. In 2016, a human skull was discovered in a mannequin that was part of an ensemble made by the Verreaux studio. Formerly known as “Arab Courier Attacked by Lions”, it was restored and returned to display at the Carnegie Museum of Natural History in Pittsburgh under the title “Lion Attacking a Dromedary”. Although apparently no attempt was made to use human skin in the Pittsburgh diorama, these cases show that there was little reticence when it came to using human materials for taxidermy displays in the nineteenth century, particularly when the human in question was considered ‘exotic’. This is supported by the fact that a popular contemporary taxidermy manual, aimed specifically at museums and travelers, opened with a paragraph on the impossibility of applying taxidermy to man successfully. The book, written by the naturalist Sarah Bowdich (née Wallis, later Lee, 1791-1856) saw six editions – the first in 1820, the last in 1843.

After listing the necessary tools and giving a number of recipes for the cleansing and preservation fluids used in taxidermy, Bowdich opened the section on ‘the preparation of mammalia’ with a somewhat disappointed-sounding statement:

1. Of man 

All the efforts of man to restore the skin of his fellow creature to its natural form and beauty, have hitherto been fruitless: the trials which have been made have only produced mis-shapen, hideous objects, and so unlike nature, that they have never found a place in our collections.

Bowdich went on to discuss the life-like wet preparations made by Amsterdam anatomist Frederik Ruysch (1638  – 1731) as ‘without doubt (…) very useful to science’, before switching to a description of a more successful practice – the preservation of skeletons. Given the tragic history of ‘el negro’ and many other violently obtained human remains in museum collections, it is a cold comfort that the naturalists of the nineteenth century failed at the taxidermy of their ‘fellow creature’.

What’s in a name: Plaster of Paris

By Marieke Hendriksen

One of the problems we face as historians studying and reconstructing recipes is that the names describing ingredients, tools, and materials change over time, and that the meaning of terms itself changes over time. This is even the case with relatively recent recipes and materials that are in theory unchanged as I recently discovered. As part of my research for the ARTECHNE project, I recently looked at instructions for making anatomical casts from plaster from 1791.

The creation of anatomical casts and models using plaster of Paris became increasingly popular towards the end of the eighteenth century, fuelled by the omnipresence of plaster in the visual arts and interior decoration, and the increasing importance of pathology and later physiognomy within the study of medicine. The latter meant that medical men were looking for durable three-dimensional ways to preserve diseased bodies and body parts that could not be preserved otherwise (e.g. in a preparation), either because decay could not be stopped or because the patient was still alive.

In his 1790 book The Anatomical Instructor, physician Thomas Pole (1753-1829) not only gave advice on how to make anatomical preparations and drawing, but also included over fifty pages on how to create, colour, repair and maintain plaster casts and models. Pole started the chapter on modelling with outlining the relevance of the quality of the plaster of Paris, or calcined alabaster, that was to be used. He explained that

“…that of a middling price is used for making of moulds; the finer sort is for casts, to be poured first into the mould, when properly prepared; after it has formed a layer of about half an inch, more or less, according to circumstances, then the coarser sort is to be used to fill up the mould, or to give it sufficient thickness.”[1]

But exactly what were the various qualities of plaster for sale in London in the 1790s made of? The term ‘calcined alabaster’ tells us little, as alabaster was and is a collective noun that designates both various kinds of light-coloured, translucent and soft stone used mainly for carving decorative artefacts (often the minerals gypsum or calcite – the former much softer than the latter), and a specific compact and fine-grained variety of gypsum. In the decades after Pole’s publication, the French chemist Antoine François de Fourcroy (1755 –1809) would distinguish nine kinds of calcareous sulfate, one of which was sulfate of lime or common gypsum. In an 1810 ‘dictionary of the arts’ Fourcroy’s sulfate of lime or common gypsum was described as follows:

“Sulphat of lime, or common gypsum, or plaster-stone. This substance is white, more or less inclining to grey, interspersed with small brilliant crystals, easily cut with a knife. it is found disposed in Paris. We shall hereafter find, that it is not pure selenite, but owes its most valuable property, as plaster, to the admixture of another kind of earth. (…) Calcareous sulphat is likewise found dissolved in waters, as in the well-waters of Paris; it is never pure, but always combined with some other earthy salt, with base lime or magnesia. This salt has no apparent degree of taste. It decrepitates if a sudden heat be applied to it; it is then of an opaque white, in which state it is called fine plaster, or plaster of Paris: by this calcination it loses about twenty in one hundred.”[2]

As this fragment suggests, plaster of Paris indeed derives its name from a large and very pure gypsum deposit at the Montmartre and Menilmontant hills in Paris – there were plaster quarries at this site at least as early as the year 500. This led “calcined gypsum” (roasted gypsum or gypsum plaster) to be commonly known as “plaster of Paris”, even after the exhausted quarries were converted into Montmartre cemetery and the Buttes de Chaumot gardens respectively in the mid-nineteenth century. Although not all plaster came from Paris at the time Pole was writing, there is a fair chance that much high-quality plaster was indeed plaster from Paris.

Today, gypsum plaster, or plaster of Paris, no longer comes from Paris, but is still produced by heating powdered gypsum to about 150 °C. When mixed with water, this forms a paste that will harden within minutes, producing an exothermic reaction, which means it warms up. You can easily buy ‘plaster of Paris’ from artist’s supplies shops and online retailers, but none of these mention the exact chemical composition. Yet before I (or anyone else) can try my hand at reconstructing Pole’s instructions I will need to find out whether the best, finest plaster of Paris still contains a percentage of lime or magnesia, what the ‘coarser varieties’ that Pole described contained, and whether these are still available.

Creating and integrating a database – work in progress

By Marieke Hendriksen

As mentioned in the post introducing the ARTECHNE project at Utrecht University last month, we are in the process of creating a database containing recipes, artist handbooks, and art theoretical texts that can clarify the development of the use of the term ‘technique’, as well as related terms referring to processes of making and doing. The database is linked to Geographical Information Software (GIS), thus creating an online historical semantic map of ‘technique’. Such maps are more than merely nice illustrations; they can reveal connections that remain hidden otherwise.

We are in the fortunate position where we can build the database on an existing one, namely the excellent Colour ConText database. However, we do not simply want to offer a copy of the Colour ConText database, we want to integrate it with other sources on artisanal practices and theories, such as recipes, books of secrets, art theoretical texts, and artist handbooks, from the period 1500-1900, in Latin, Dutch, German, English, French, Italian and Spanish. The entire database has to be searchable with advance searches, allowing users to search full text for occurrences of terms, in particular geographical or linguistic areas and periods, or to trace the changing uses and meanings of particular terms over time, linking various forms of terms and different terms with a similar meaning in relational tables and glossaries.

For example, if we want to know how instructions for making paint have changed in the low countries between 1600 and 1900, we want to be able to select all available sources from that period and area and search them for imperatives, nouns, measurements, and particular ingredients. We also want to be able to distinguish between printed and manuscript sources, artist handbooks and household recipes books, and ideally we want to be able to search annotations and marginalia too, as well as differences between various editions of the same work. That means a lot of different parameters have to be specified for each source, and everything we include must be carefully checked before it is added.

One of the problems we encountered when selecting the first sources we wanted to add was the low reliability of Optical Character Recognition software when used on early modern printed sources – a problem I have written about on my own blog before. We do not just want to combine existing digitized sources in our database, but also to add texts that have not been digitized and made searchable thus far. However, that often involves lengthy correction processes. One of the solutions we are considering is crowd sourcing such corrections. Fortunately, we can also add many digitized sources that are available under Creative Commons licenses (i.e. from the Digital Library of the Netherlands), and various researchers have contacted us to discuss adding their own datasets to the database.

The first edition of the database is now online – have a look at http://artechne.hum.uu.nl!  Please note that this is a first version, and that the database will be improved and continue to grow for the duration of the project. Over the next few months, we will focus on increasing searchability and adding new sources. If you have any questions or suggestions, please contact us at artechne[at]uu.nl.

Finally, we will also explore the options of maintaining the database after the end of the ARTECHNE project, for example by depositing the datasets or even the entire infrastructure with an archival institution.
