T1 - Connoisseurship and the Investigation of Materiality: Four “Rembrandt” Drawings in Weimar N2 - The aim of this paper is to present the productive interplay of connoisseurship and material analysis when dealing with drawings by Rembrandt – or previously attributed to him – in the collection of the Klassik Stiftung Weimar. This concerns the more precise determination of the drawing materials used and the reconstruction of the genesis of the drawings discussed. The material analysis allows us to decide whether and how Rembrandt’s inks can be used to determine authorship at all. The “material turn” in drawing studies thus intervenes in the discussion about authorship and opens up a broader production aesthetic perspective. No longer the “style” but rather the handeling becomes the decisive criterion for answering the question “Rembrandt, or not?” KW - Archaeometry KW - History of Art KW - Drawings KW - Rembrandt PY - 2021 SN - 0044-2992 VL - 84 IS - 4 SP - 483 EP - 518 PB - Deutscher Kunstverlag CY - Berlin/München AN - OPUS4-54342 LA - eng AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany ER - TY - JOUR A1 - Bodechtel, S.

Insights into the painting technique along with art historical comparisons provided the opportunity for a better understanding of the painting’s genesis, in particular concerning an early reworking of the background by the artist. A recovery and reconstruction of the earlier version of the background is now possible. The discovery of zinc in distinct passages of the painting, as well as the grey-black pigment stibnite and glass particles used as a supplement in paint layers are of special interest. The technological investigation initiated a discussion about the circumstances of the revision, as well as the painting’s relation to Vasari’s Lives of Artists.

T1 - Disclosing glittering and sparkling effects in 20th-century reverse glass paintings: a study of metallic pigments and metal foils by means of in situ XRF and DRIFTS analysis N2 - This work presents a spectroscopic study of metallic pigments and metal foils used in reverse glass paintings that were created between 1912 and 1954. Metallic pigments induce a notable sparkling effect by means of the lateral incidence of light, whereas metal foils enhance the gloss and create a glittering effect when the painting is viewed in reflected light. Both effects were desired features especially in modern reverse paintings on glass and applied by artists in manifold creative manner. The paper gives an overview on the composition of the metalfoils and metal pigments in 14 works as determined in situ by X-ray spectrometry. Metal foils made of tin, brass, aluminium and silver were found in nine paintings. Gold imitating Cu-Zn pigments in different hues and with various Cu/Zn net intensity ratios were recorded for six paintings. Silvery pigments were identified mainly as Al pigments, but also as Cu-Zn-Ni alloy in one case. Other uncommon metallic pigments were detected in Arlequin vindicatif (c. 1925) by Floris Jespers, who used not only Cu-Zn and Al pigments, but also brownish Cu and Cu-Zn-Sn pigments. Non-invasive diffuse reflectance infrared Fourier-transform spectroscopy (DRIFTS) was used to classify the binding media of the metallic pigments. Drying oil and natural resin probably mixed with oil were the most common binding media. A polysaccharide-based binder was found in the silvery Cu-Zn-Ni pigment of Ohne Titel (1954) by Marianne Uhlenhuth.

A1 - Rabin, Ira T1 - A study on early european inks from St. Paul in lavanttal N2 - Typology of Inks Archives and museums around the world contain a vast number of manuscripts that were written in different inks: carbon inks, plant inks, iron-gall inks and mixed inks. Yet most archaeometric studies of manuscripts focus on the palette of pigments found in illuminated manuscripts whereas identification of the inks is still largely based on cultural-historical studies and visual inspections. One of the reasons of this disproportion in the studies can be explained by the properties of Raman spectroscopy, the technique of choice for identification of pigments. In contrast, this technique is only partially viable when dealing with organic colourants. Brown and Clark discuss these difficulties and the uncertainties of identification of iron-gall inks by Raman spectroscopy in their pioneering work on early medieval Anglo-Saxon manuscripts (K. Brown and R. Clark 2004). To facilitate instrumental analysis of inks, we have developed a protocol that starts with the identification of the inks type (Rabin et al. 2012) which doesn’t require complicated instrumentation and can be carried out by paleographers and codicologists. Three typological ink classes The black writing materials used in manuscript production in Antiquity und Middle Ages can be sorted in three typologically different ink classes: soot, plant and iron-gall. Soot ink is a fine dispersion of carbon pigments in a water soluble binding agent; plant-based ink consists of a solution of the tannins extracted from gallnuts or tree bark; iron-gall ink, is produced by mixing a soluble compound of iron (II) with gallic or tannic acid extracted from gallnuts or tree bark. Therefore, iron-gall ink presents a boundary case between solution and dispersion ink, in which a water-soluble preliminary stage oxidizes and evolves into a black, insoluble precipitate similar to the carbon pigments when the writing is exposed to air (Krekel 1999). The additional category of mixed inks, i.e. inks produced by addition of various metals to the soot inks or intentional mixing of iron-gall and soot - based inks started attracting scholarly attention only recently because their significance was established only a short while ago (Brun et al. 2016, Colini 2018, Nehring et al. 2021). We suggest that plant and mixed inks build a bridge from the carbon ink of Antiquity to the properly formulated iron-gall ink that became a standard black ink from the late Middle Ages to the 19th century when it gave way to modern inks.

Soluble inks are based on plant or insect dyes forming a water solution. In the early European Middle Ages brown plant inks were usually produced from the blackthorn bark and wine. In contrast to these soluble brown inks, one of the oldest black writing materials was produced by mixing soot with gum arabic or animal glue dissolved in a small amount of water. From Pliny’s detailed account of the manufacture of various black carbon inks, we learn that producing pure soot of high quality was not an easy task in Antiquity. Iron gall inks are a borderline case between these two groups. They are produced from four basic ingredients: gallic acid, an iron-containing component, gum arabic as a binding media, and an aqueous medium such as wine, beer, or vinegar. By mixing gallic acid with soluble iron ions, a water-soluble ferrous gallate complex is formed. Exposure to oxygen leads to the formation of insoluble black ferric gallate pigment. Due to the variety of recipes and the natural origin of raw materials, there is a wide range of different components and impurities in writing inks. The Bundesanstalt für Materialforschung und -prüfung (BAM) together with the Centre for the Study of Manuscript Cultures in Hamburg (CSMC) has developed a protocol for ink analysis. It consists of a primary screening to determine the type of the ink and a subsequent in-depth analysis using several spectroscopic techniques (X-ray fluorescence analysis and vibrational spectroscopy). This contribution presents a qualitative and quantitative analysis of historical writing inks to characterize distinguishable inks in manuscripts, to determine the origin of manuscripts, and to assign unknown fragments to time and place.

T1 - Detection of Fakes: The Merits and Limits of Non-Invasive Materials Analysis N2 - This paper addresses the sensitive issue of authenticating unprovenanced manuscripts of high monetary value to certify they are genuine. Over the last decade, the popularity of material studies of manuscripts using non-destructive testing (NDT) has increased enormously. These studies are held in especially high esteem in the case of suspicious writings due to the methodological rigour they are reputed to contribute to debate. We would like to stress that materials analysis alone cannot prove that an object is genuine. Unfortunately, audiences with a humanities background often tend to disregard the technical details and treat any published interpretation of instrumental analysis as an objective finding. Four examples are outlined here to illustrate what questionable contributions the natural sciences can make in describing manuscripts that have actually been forged.

During the last years a lot was done to improve the mere technical side of the techniques. Especially in the case of XRF mapping experiments the acquisition speed needed to be increased to allow mapping in the high resolution demanded by the challenges at hand. High resolution in moderate times can now be achieved, but with the price of proportionally increased amount of data that needs to be processed ideally in parallel to the measurement. The classical approach in XRF spectroscopy of elemental fitting of the spectral data does not even come close to fulfill any on the fly processing time constraints and will consume too much processing time in the foreseeable future. In this paper we will discuss the applicability of modern statistical data processing methods to XRF mapping of iron gall ink palimpsests. We will present a comparison of a new approach based on principle and independent component analysis (PCA and ICA) and the standard element mapping method. We will show that a reduction in processing time of almost two orders of magnitude can easily be achieved.

N2 - While studying the socio-geographic history of inks, division 4.5 (Analysis of cultural artefacts and assets) of the BAM (Bundesanstalt für Materialforschung und -prüfung) in Berlin together with the Centre for the Study of Manuscript Cultures in Hamburg has developed a protocol for ink analysis. It consists of a primary screening to determine the type of the ink, and a subsequent in-depth analysis using several spectroscopic techniques. Using this protocol, scientists can assist scholars in addressing a rather broad range of historical questions that cannot be answered unequivocally through scholarly research alone. Among these are investigations on collaboration between scribes and scriptoria, on the usage and annotation of manuscripts and on their path through time and space in general. This research can thus help to reconstruct the circumstances of the production of written heritage as well as their history and transmission. To facilitate the dialogue between the scholars and the scientists a simple optical tool was developed to allow the scholars to perform preliminary ink analysis required for formulation of the question that in turn can be answered by scientific in-depth investigations. In this paper, ink types and their identification method is accompanied by examples of the recent work conducted on parchment manuscripts in the Austrian National Library.

N2 - The aim of the lecture is to present the productive interplay of connoisseurs and material analysis using the example of selected drawings from the Rembrandt collection of the Klassik Stiftung Weimar. We try to determine the point at which the question of the materiality of the drawings makes sense in the traditional discourse of connoisseurship. On the one hand, this involves the question of authorship – Rembrandt – or not? – and the locating of attributed drawings in the context of the work. On the other hand, it is about making drawing processes visible, characterizing ways of drawing and workshop practices as well as distinguishing different forms of reworking and copying within the Rembrandt workshop. The material analyses culminate in the question of whether Rembrandt’s inks can be distinguished at all. It becomes apparent that the newly gained knowledge about the materiality of the drawing no longer reveals itself to the “mere” view of the connoisseur. Rather, it is only generated by the digital image. The rhetoric of connoisseurs must therefore be contrasted with the necessity of a hermeneutics of the digital image. The envisaged “material turn” of drawing science is thus simultaneously able to take up the critique of the question of authorship, which has been growing ever more recently, and to transfer it to a more comprehensive perspective of aesthetics of production.

Possible application of a non-destructive analytical method N2 - VIS-spectrometry is a rapid, non- invasive, mobile method that offers a first overview of possible colorants used for painting. This is worked out in detail for European paintings and applied for artefacts and illuminated manuscripts. Manuscripts from Asia for example show colorful decoration identified to be mostly prepared with mineral pigments such as cinnabar, azurite, malachite or orpiment, which can be well confirmed by elemental analyses due to their color-giving metal ions. This is not the case for the colorants used in pictorial manuscripts from pre-Hispanic America, painted mainly with organic dyes from plants. The palette of colors used by the Aztecs is very rich due to their extensive empire and long- distance communication with vassal states liable to tributes including dyes of high quality. These include for example red cochineal, yellow zacatlaxcalli, tagetes, safflower, and achiotl, as well as blue indigo, or matlalli.

T1 - Insights-into-the-Digital-Recovery-of-the-Scythica-Vindobonesia N2 - The Scythica Vindobonensia, the new fragments on Gothic incursions into Roman provinces in the Balkans in the middle of the third century AD that were revealed some years ago in a Greek palimpsest at the Austrian National Library in Vienna (ÖNB), are commonly considered as one of the most important additions of the last decades to the corpus of texts from classical Antiquity. Tere is a high degree of confdence among scholars in supposing that the fragments come from the lost work Scythica written in Greek by the third-century historian P. Herennius Dexippus (Δέξιππος) of Athens. The new fragments have hence also been called Dexippus Vindobonensis. In his Scythica, Dexippus recorded wars of the Romans with the Goths (and other tribes) whom he called Scythians. The work had been hitherto known only from excerpts and quotes by later authors. Eight pages of a Byzantine manuscript copy of the ancient text have survived hidden underneath the visible surface of the last four parchment folios of the Vienna manuscript Historicus graecus 73, f. 192r -195v4. The copy is written in a Greek calligraphic minuscule which has been estimated by palaeographers to be of the middle or the second half of the eleventh century. In the thirteenth century, the text (on each of the eight pages arranged in one column, with 30 lines per page) was washed of the parchment and the valuable material made from animal skin was re-used for Christian texts. The new writing largely covered the faded remnants of the original text. It thus became hidden from the human eye for more than seven hundred years. Its discovery by Jana Grusková, a classical philologist specialized in the transmission of Greek texts, resulted from a systematic review of all Greek palimpsests kept at the Austrian National Library in Vienna at the beginning of the twenty-first century and a detailed examination of the four folios in 2007-20097.

T1 - Colours on East Asian Maps N2 - Maps and colours have a close connection. Drawn or printed in black on white, subsequently added colours enhance maps with additional information. Colours were not just there to improve maps aesthetically, but they regulated how they were read and thus reinforced their meanings, significances and ideas. Colour is an important key to a more precise understanding of the map’s purposes and uses; moreover, colours are also an important aspect of a map’s materiality. The material scientific analysis makes it possible to find out more about the making of colours and the process of colouring maps. By skillfully deploying colours, map colourists were able to create mimetic representations of nature or codify information in an abstract form. The use of colours involved many considerations as to the materials. ‘Reading’ colours in this way gives a glimpse into the social lives of mapmakers as well as map users and reveals the complexity of the historical and social context in which maps were produced and how the maps were actually made. Within the scope of the three-year joint research project Coloured Maps (2018–2021), we undertook an in-depth and systematic study of hand-drawn and hand-coloured maps from East Asia in the Museum am Rothenbaum (MARKK) in Hamburg and produced between the seventeenth and twentieth centuries. With a multi-perspective approach and transdisciplinary methods (humanities and the sciences), we were able to pool and compare the research results from different fields of research on Asian maps. The aim of this publication is to provide a first general overview of the subject of colours on maps in East Asia in the period from the seventeenth to the early twentieth century and to stimulate further research on the topic.

Taking as test case Leonardo da Vinci’s Manuscript with anatomic drawings and notes, which is stored in Weimar, we clarify fundamental steps in the chronology of this folio. By means of microscopy, infrared reflectography, UV photography, and X-ray fluorescence analysis, we were able to identify various types of sketching material and several varieties of iron gall ink. For his sketches, Leonardo used two different sketching tools, a lead pencil and a graphite pencil, as well as several types of ink for developing these sketches into drawings. With regard to ink, it is important to observe that there is no difference between the ink Leonardo used for drawing and the ink he used for writing text. Based on the materials analysed, we suggest a chronology for the creation of this unique folio.

N2 - The fourth-century Greek Bible manuscript Codex Vaticanus B (Vat. gr. 1209) contains pairs of horizontally aligned marginal dots known as distigmai, which correspond to textual variants in other manuscripts. The production of the distigmai has been variously dated to the 4th or 16th centuries. A fourth-century date would prove the early existence of hundreds of textual variants, many of which are otherwise only witnessed by later manuscripts. Near infrared microscope reflectography combined with micro-X-ray fluorescence spectroscopy proved that the distigmai, both those categorized as “apricot” (which are visually similar to the ink of the original main text) and “chocolate” (which are visually similar to the reinking of the main text) were written with ink(s) made from chemically purified vitriol, a process that only became standard in the 16th century. As a result, there is no reasonable chance that the distigmai were written in the fourth century. Horizontal lines that have been hypothesized to function as text-critical obeloi were written in the same ink as the original main text, which differs completely from that of the distigmai. In other words, the distigmai and horizontal lines tested were not produced during the same writing session and are separated by more than 1,000 years, making it impossible for them to have functioned as conjoining text-critical symbols in the 4th century.

T1 - A New Standard Protocol for Identification of Writing Media N2 - Our standard protocol for the characterisation of writing materials within advanced manuscript studies has been successfully used to investigate manuscripts written with a pure ink on a homogeneous writing surface. However, this protocol is inadequate for analysing documents penned in mixed inks. We present here the advantages and limitations of the improved version of the protocol, which now includes imaging further into the infrared region (1100−1700 nm).

Part 2: a case study of Carolingian manuscripts N2 - With this paper, we would like to contribute to the study of black writing materials by investigating the black inks used in the manuscripts from monastic production in the eastern part of the Frankish kingdom, especially in the region of Lake Constance and in Bavaria and dated to the period between the 8th and the 10th centuries. The corpus under study contains manuscripts with formulae, i.e. model letters and charters, besides numerous other types of texts with no clear separation between them (for example by titles). Sixty-three manuscripts have been studied with the aim of reconstructing the history of both their copying and their use. To this aim, we adopted a non-invasive approach that included near-infrared imaging and X-ray fluorescence spectroscopy for on-site measurements, supported by historical and palaeographic analysis. The results obtained in this project are compared with several other archaeometric studies of contemporary manuscripts with the general aim of understanding the use of black ink in medieval manuscripts.

T1 - Materials and materiality as keys to understanding a map of Mount Kailash N2 - While graphic and linguistic content is central to the identification of maps and can provide insights into the concepts and systems of rules, ideas and beliefs that led to their production, the materials that constitute maps may speak about manufacturing processes, the provenance of raw materials, the practical and technical knowledge of the mapmakers, and the use of the maps. This contribution underscores how the materials employed in Tibetan maps reveal aspects of their context and trajectory. Furthermore, materiality, conceptualized as a convergence of matter and imagination, can yield even more profound insights into artefacts like maps. Through a detailed case study of a map of Mount Kailash in the tangkha format and a specialized material-scientific analysis of the colourants employed in its creation, this contribution explores how a map can ‘talk’ through its materiality. With this case study it will show how Tibetan Studies can benefit from interdisciplinary collaboration. Crossing the field’s traditional boundaries and working with other disciplines, we argue, is absolutely essential for serious research.

While colouring seems at first glance simply superficial ‘prettifying’ of maps, most maps were given colours for other reasons: colour is an important key to understanding the function and use of maps. The use of colours, the choice of where to assign them and the meaning given to them has accordingly never been static but has changed over time. In this context, the three aspects: colour system, colour scheme, and colour code are of particular importance. Material scientific analysis makes it possible to find out more about the material composition of colourants (pigments and dyes) on maps. The study of colourants provides insights into the production conditions and use of maps. Furthermore, it offers clues about colour changes and forms the basis for appropriate restoration concepts.
