Artisanal recipes are considered to be primary sources in the historical study of artistic practices and materials. Prominent examples of such documents include the De diversis artibus attributed to Theophilus and the Libro dell’arte by Cennino Cennini. However, hundreds of other such examples exist and were still largely unknown. In his 2001 publication The Art of All Colours, Mark Clarke compiled an inventory of 400 source documents, dating from the production of the first artists’ recipe collections up to 1500. Since then, dozens of other surviving writings containing artisanal recipes have been discovered. Many more recipes were written down in manuscript and print in the period after 1500.

The initial goal of the Colour ConText database is to facilitate the consultation and exploitation of a large corpus of recipes. The core data consists of medieval and early modern manuscripts and printed books.

The ‘Sources’ page

To date, more than 500 sources (including manuscripts and printed texts) have been entered into the database, specifically located on the ‘Sources‘ page (fig. 2). In the ‘List view’, the entries are tabulated optionally by place of conservation or edition, or by title, author or date. Detailed information such as the source’s title, language, location, provenance and circulation of these manuscripts and books (place and date of origin/publication), scribes or authors, previous owners, and a description of their technical and/or general content can all be viewed on this first interface, on the ‘detailed view’.

From now, these sources can be searched by title, or by place of conservation or edition.The database also allows access to digital images of these sources via European Cultural Heritage Online (ECHO), or via digital collections made available by external institutes.

The ‘Recipes’ page

The database also makes the content of the recipe collections accessible at the level of the individual recipes. To date, more than 6,500 recipes—some consisting of only a few lines, others covering several folios—have been transcribed and recorded on another specific page within the database. The ‘Recipes‘ page allows users to consult the transcription of a particular recipe, and sometimes also provides an English translation. This translation may either have been done in the framework of this project or be reproduced directly from existing edition. In such a case references to secondary sources, together with the related bibliographical data, are specified. Finally, this layout also gives access to the specific image of the original recipe text (fig. 3).

Users can search for a specific request by library, source, title or ID number—a consecutive and unique number assigned to each individual source. It is also possible to search for specific words that appear either in the transcription or the translation of the recipe.

Thanks to subject classification, keywords can be used when researching specific recipes, methods or materials. The general search button – situated on top of each page – allow users to combine an ingredient with a specific technique, mentioned in a limited geographical/chronological framework, when making their search.

For example, the combined search for ‘alum’ (an potassium aluminium sulphate notably used in the art of dyeing and for the producing of lake pigment) and the colour ‘red’ shows a number of entries, which can be further filtered by glossary, artistic technique or content type. We can read that 305 recipes are concerned with the substance alum and with the production of the colour red. These recipes are more specifically related to painting, illuminating, writing, dyeing, gilding and metalwork (fig. 4).

The Colour Context database can also help to identify specific, datable practices and materials. For example, we have observed that a significant number of procedures involving anthocyanin colourants (obtained from the juice of flowers and berries, such as poppies, cornflowers or blueberries) are specifically described within a certain group of manuscripts. More precisely these texts were written in the south of Germany and the north of France between 1400 and 1560.

The ‘Glossary’ page

The database also includes a complete list of the ingredients and substances mentioned in the recipes, indexed both by their current scientific name (‘Current names’) and by the ‘historical’ terms precisely as they are written in the source texts (‘Historical names’). Objects and materials are linked by relational tables that allow the retrieval of all the different historical names used for one particular material—detailing the historical written context—as well as enabling the user to see the various materials that may be related to a specific name.

These lists notably shed light on the diversity of colour names and the complexity of the varied colour terminology used in artisanal recipes. For example, the puzzling denomination ‘red of Paris’ relates to several different substances. In the Illuminier Buch von Valentin Boltz von Ruffach (first edition dated of 1549), it is used to designate a red pigment obtained from brazil wood (Caesalpinia sappan Linn. or Caesalpinia echinata Lamarck). However, other sources make a distinction between Paris red and the red pigment obtained from brazil wood by recommending the use of either the former substance or the latter (‘Ein guot röselin oder pfirsÿg bluot Nu nim presilgen oder paris rot’, Colmarer Kunstbuch, pp. 124-125, recipe 35). In Heidelberg, Cod. Pal. Germ. 489 [252], ‘Paris rot’ is a colour made from brazil wood and an unspecified lake called ‘Lacta’. Within this same manuscript, recipe [391] describes the preparation of ‘Rotenn Paris’ from a lake. It has therefore been hypothesized that this appellation was used as a way to distinguish a specific hue.

The Strasbourg Tradition of Artists’ Recipe Books Part I: Restoring a lost artists’ recipe book

By Sylvie Neven

During the mediaeval and early modern periods, artisanal knowledge was notably transmitted in collections of recipes, of which hundreds of examples exist in addition to the well-known ones–such as the De diversis artibus attributed to Theophilus (ca. D 1100)[i] or Il libro dell’arte of Cennino Cennini (ca. 1390)[ii]. The so-called Strasbourg Manuscript is a well-known example of this type of artistic literature. This artist’s recipe book, whose content has been dated to the beginning of the early fifteenth century, is believed to be the oldest German-language source for the study of Northern European painting techniques.

The art-technological instructions of the Strasbourg Manuscript cover a wide range of crafts. They are mostly dedicated to painting and illuminating and, in particular, to the preparation of pigments (refining, grinding, suitable mixing, building up of layers of paint, and using gold or its imitation in gilding). Some recipes concern the manufacture of specific binding agents, glues and varnishes to be used on various artistic supports. Others correspond to instructions for auxiliary crafts such as polychromy and mural painting, dyeing of textiles and skins, the preparation and the colouring of the parchment support, or the working of metal.

Unfortunately, the Strasbourg Library Ms. A VI 19, in which these technological instructions were originally preserved, was destroyed during the 1870 fire in the Strasbourg Library. By chance, a few decades before, a copy of the recipe book was made for Sir Charles Eastlake, the first director of the London National Gallery. This was partly published in 1847. The two later main editions of the text are based solely on this transcription[iii].

Since its discovery, the text of the Strasbourg Manuscript has been frequently cited by scholars and has been renowned for being the Nordic counterpart of the famous Libro dell’arte by Cennino Cennini. Numerous studies have referred to its technical content within the context of analytical reconstructions or for the purposes of artistic attributions. However, the previous editions of the recipe book – on which these studies relied – contained many divergences and contradictions. No one has raised the question of the reliability of the nineteenth copy, nor questioned the degree of similarity between this document and the mediaeval recipe book. A few years ago, examination of the modern transcription led me to suspect that its accuracy is questionable; closer reading of the artistic recipes of the Strasbourg Manuscript highlighted anomalies within the text.

To favour the current use of the Strasbourg recipe book and to counteract the lack of the original text, I have proposed a new revised edition and translation, based on the modern copy, the two editions and other historical witnesses of the text[iv].

As with many mediaeval and early modern recipe books, the Strasbourg Manuscript was the result of copying and compiling various sources. Its content appears in other contemporary recipe books and persists in treatises such as the edition of the Valentin Boltz von Ruffach’s Illuminierbuch (1549). The manuscripts related to this tradition mainly originated from the South of Germany and North of France. Within this textual and technical ‘Tradition’, the Strasbourg Manuscript is the oldest surviving example[v].

The new edition of the Strasbourg Manuscript allows an overview of the current structure of this recipe book, which has had several amendments and loss of physical material. It aims to determine the location of corrected or amended errors or lacuna in the nineteenth copy, thus offering an opportunity to reconstruct the text of the lost manuscript. The conclusion? The text of the Strasbourg Manuscript is a result of contributions from textual and oral sources.

The systematic comparison of all the witnesses of this tradition of artists’ recipe books, taking into account the inherent characteristics of these writings (historical, codicological, textual and technological), has also been exploited for diverse purposes–which I will discuss in future posts.

Within the witnesses of this tradition, the Strasbourg recipe book has not been copied word-for-word. It has been subject to additions, elisions and corrections. Studying the textual modifications during its spread and interpretation of its variations or errors across provides a deeper understanding of the historical context for its production. It has also suggested the ways in which these sorts of recipe books were handled by their many scribes and owners.

Finally, comparative analysis of all the witnesses to this textual and technical tradition clearly signals their analogies and divergences, which are meaningful in terms of the original function and use(s) of these texts. This kind of observation, and the conclusions that can be made from them, allow for a better assessment of the relevance of artists’ recipe books within the framework of historical artistic practices.

[v] A new philological analysis of Eastlake’s transcription has allowed a more precise date to be suggested. Orthographical features and connections with some archival documents from the Strasbourg Chancellery and documents of the painters’ guild regulations allow us to propose a date of ca. 1400.
