T1 - Tintenarten in mittelalterlichen hebräischen Manuskripten: eine typologische Studie / Inks used in medieval Hebrew manuscripts: a typological study N2 - Schon seit einiger Zeit konzentriert sich unsere Arbeit auf die Geschichte der in Europa und dem Nahen Osten verwendeten Schreibtinten, zum Teil angeregt durch die umfassende Publikation Les encres noires au Moyen Âge jusqu’à 1600 von Monique Zerdoun. Die gründliche Auswertung der darin präsentierten Schriftquellen führte Zerdoun zu dem Schluss, dass sich die bemerkenswerte Ausbreitung der Eisengallustinten nur durch experimentelle Studien dokumentieren ließe. Die Untersuchung der zu Korrision führenden Tinte, die für das Genesis-Apokryphon (1QGenAp)1 verwendet wurde und sich entsprechend der antiken Rezeptur des Dioskurides als Rußtusche mit einem beträchtlichen Kupferanteil herausstellte (Oltrogge 2008), lieferte den zweiten wichtigen Beweggrund, eine Brücke von den Rußtuschen der Antike zu den Eisengallustinten schlagen zu wollen, die sich sowohl in Europa als auch weit darüber hinaus vom 12. Jahrhundert n. Chr. an zum beliebtesten Schreibmaterial entwickelten. Obwohl Eisengallustinten als universelles Schreibmaterial galten, lassen sie sich anhand ihrer charakteristischen Eigenschaften unterscheiden, da weder Standardrezepte Verwendung fanden noch stets identische Rohstoffe eingesetzt wurden. Darüber hinaus ermöglicht die Fülle der überlieferten Rezepte die Klassifizierung historischer Tinten nach geografischen Kriterien. Gleichzeitig gerieten die Rußtuschen nicht in Vergessenheit: in manchen Regionen des Nahen Ostens haben sie bis heute ihre Bedeutung bewahrt. N2 - For some time now, our group has been focusing on the history of the writing inks used in Europe and the Middle East. This work was partly inspired by the excellent book Les encres noires au Moyen Âge jusquà 1600 by Monique Zerdoun. The exhaustive research on the written sources that she presented allowed her to conclude that only experimental studies could produce a record of the inexorable expansion of iron-gall inks. Our study of the corrosive ink used in the Genesis Apocryphon scroll (1QapGen),1 which turned out to be carbon ink with a substantial amount of copper in accordance with Dioscurides’ ancient recipe (Oltrogge 2008), served as a second strong reason for wanting to build a bridge from the carbon inks of antiquity to the iron-gall inks that became the most popular writing medium both in Europe and far beyond from the twelfth century CE onwards. Even after achieving overwhelming popularity, the iron-gall inks preserved their individuality, remaining remarkably different from each other as neither a single standard recipe nor identical raw materials could be used. Moreover, the wealth of recipes that have been transmitted indicates that historical inks can be grouped geographically. At the same time, carbon inks did not fall into oblivion: in many a region of the Middle East, they have remained important to this day.

Most of the fragments are remains of medieval manuscripts of various content and age, not particularly remarkable; but one small, badly damaged leaf attracted the attention of the research group due to its pronounced archaic features.2 The leaf measures ca. 200 (height) x 160 mm (width).3 The text is laid out in two columns, 25 written lines each. The upper written line is placed under the upper blindly ruled line. The pricks are poorly visible. It seems that the “primary pricks”, intended to support the making of the vertical ruled lines, were set at the top and bottom (?) horizontal ruled lines. The outer edge of the leaf crumbled, and it is impossible to make any observation concerning the pricks for horizontal ruling (“text pricks”).

The uncertain archaeological provenance of a large part of the collection added an additional difficulty to the formidable task of sorting thousands of fragments. After sixty years of scholarly research, the questions of origin, archaeological provenance, and correct attribution of the fragments are still debated. In many cases, material characterization of the scroll writing media delivers answers to these questions. Physical and chemical examination of the skin-based material of the Dead Sea Scrolls started shortly after their discovery. Subsequent studies dedicated to long-term preservation resulted in a respectable body of knowledge about this material, in many ways very different from medieval parchment. A new multi-instrumental approach, developed for an accurate characterization of the highly inhomogeneous 'parchment' of the Dead Sea Scrolls, might lead to a reliable reconstruction of their history. This approach is illustrated by the case studies, in which we discuss the specific questions of origin (1QHa), archaeological provenance (11QTa), and post-discovery interventions (1QapGen ar).

The collection of mostly Jewish documents that vary in genres, languages and writing supports contains a large number of early medieval Hebrew manuscripts. The Geniza provides sources for the literary, linguistic, historical studies of the various aspects Jewish life. As the documents attest, at least two Jewish communities co-existed in Fustat up to 11th century: a so-called Babylonian and Palestinian. These communities had different leaders, different traditions and lived independently. The differences seem to manifest themselves also in the paleographical, codicological and some material properties of the manuscripts produced by each community. The aim of this project is to compare the inks used in the Jewish documents depending on different variables: support (paper, parchment), purpose of the manuscript (legal, private, religious), provenance of the scribe. For the determination of the inks type and composition we had to choose non-invasive, non-destructive and portable techniques to analyze the corpus directly on-situ. The analyses were carried out with a micro-X-ray spectrometer ArtTAX® (Bruker GmbH) and a digital stereomicroscope features built-in LED illumination at 395 nm and 940nm, Dino Lite. We would like to stress that though the methods of material analysis listed above have been successfully employed in the field of cultural heritage and conservation including ancient and medieval manuscripts they have not yet been used to study fragments from the Cairo Genizah. Therefore, we believe that this research project is a pioneering study that will provide new insights into the history of Hebrew writing materials, their production techniques and materials and, thus, contribute new data to the field of Hebrew paleography.

Evidence of different parchment manufacture in the fragments fromReed collection N2 - This work presents the non-destructive spectroscopic characterisation of original Dead Sea Scrolls (DSS)parchment fragments from Ronald Reed collection. The fragments are of paramount importance becausethey have never been subjected to any treatment of preservation and restoration, this allows to investi-gate the manufacturing method of real original Jewish parchments. The manufacture of “sacred” Jewishparchments, in fact, is traditionally supposed to use a superficial tannin treatment. To study the DSS frag-ments, it was necessary both to analyse mock-up samples, especially manufactured in order to reproduceancient Oriental Jewish ritual parchments, and to compare the results with those obtained in the analysisof modern and ancient Western Jewish ritual parchments, in order to test the effectiveness of the selectedspectroscopic techniques. Traditionally, the main difference between Oriental and Western traditionalparchment preparation consisted in the dehairing method: enzymatic for Oriental and lime-based forWestern. Moreover, a finishing treatment with tannin was supposed to be applied on ritual Jewish parch-ments. The need of reference samples derives from the knowledge that each parchment preparation,treatment and degradation can induce structural modifications that affect the spectral features. FourierTransform Infrared Spectroscopy by Attenuated Total Reflection (ATR-FTIR), FT-Raman and m-Ramanwere used in this study. The experimental results allowed us to recognise, with different sensitivity, thepresence of tannin by using m-Raman and IR spectroscopies and to prove that not all the archaeologicalsamples were manufactured in the same way with vegetal extracts. Many salts (tschermigite, dolomite,calcite, gypsum and iron carbonate) were found on the surface of DSS fragments. They can derive fromthe degradation processes and storage environment before the discovery or from the manufacture. More-over, the different sensitivities and instrumental characteristics of the used techniques permitted us toestablish an analytical protocol, useful for further studies of similar materials.

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.

In the framework of the ‘PAThs’ project, archaeometric analyses complement the information pieced together by a range of disciplines in the field of humanities. The use of different complementary analytical techniques provides information on the type of ink used and its elemental composition, unveiling interesting details regarding the materials and methodology of manufacturing of writing media. Moreover, this contribution takes a step forward and discusses the possible existence of a regional arrangement in the elemental composition revealed in the inks studied.

The appearance of the ink employed to write the appellations was significantly darker than that of the surrounding ink. X-ray fluorescence analysis (XRF) has shown that the light and dark brown inks had similar elemental compositions, but contained different ratios of iron to potassium, which could be explained by the use of different batches of ink. According to some medieval sources, the divine appellations were sometimes filled in during a second stage of writing in the presence of ten men from the Jewish community. In Erfurt 7, the two-stage procedure was only performed in the first 1.5 columns of the original sheets, suggesting it may have been part of a public ceremony inaugurating the writing of the divine names in the scroll. Erfurt 7 emerges from this study not only as a ritual object used for liturgy, but as a rallying point for the Jews of Erfurt to come together as a community to express their reverence for the written form of God’s name. The divine name YHWH ( יהוה ) was written in a smaller script than the surrounding text on three replacement sheets using the same two-stage procedure. The ink used on the replacement sheets contained zinc, which is characteristic of other Erfurt manuscripts as well. This suggests that Erfurt was the place where the scroll was used, cherished and eventually repaired.

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.

The success of their contribution depends strongly on the formulation of the question and the choice of the methods to obtain the requested answer. Therefore, one should try to go beyond the understanding of the basic principles of the scientific analysis. We will start with a glance at the basic principles of the techniques used in the material science for determination of the elemental composition (X-ray emission) and molecular composition (FTIR & Raman). We will move then to the bench and mobile equipment commonly used in the field of cultural heritage. At the end we will choose a question to be answered and design an ideal experiment that will be modified according to the limitations dictated by on-site conditions.

A1 - Calvillo, Nelson A1 - Rabin, Ira T1 - Did the Original Scribes Write the Distigmai in Codex Vaticanus B of the Bible (Vat. gr. 1209)? 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.

This was due partly to the number of newly discovered fragments and to the invention of new instruments and scientific procedures to identify animal skins and produce qualitative means to demonstrate specific preparation reagents and techniques. The invention of various means of analyzing the DNA of organic materials brought about a revolution in archaeology and in conservation. Difficulties in overcoming contamination of archaeological samples resulted in a number of controversies but also produced advances and improvement in the techniques of ancient DNA analysis and interpretation of results.

To define a type common to a group of drawings, we determine elements that are common to them based on style and the use of identical materials. To that end, we investigated about 750 Dutch drawings from the sixteenth century at the Dresden Kupferstich-Kabinett using art historical and scientific methods. In this work, we present a detailed analysis of 30 drawings ascribed to the Egmont Master.

However, this protocol is inadequate for analysing documents penned in mixed inks.

A preliminary study of the library showed that the collection was extended and profoundly renovated in the nineteenth Century, in the course of the revival the monastery had during the reign of King Yohannas IV (1872-89). The shaping of the collection was apparently linked to the figure of the powerful abbot, Gäbrä Giyorgis, who donated dozens of books of diverse provenance, which he himself gathered or received as gifts.1 As the result, the extensive library contains a huge amount of information, but its heterogeneity poses a very serious challenge to the researcher.

The first one is a fine dispersion of carbon pigments in a water-soluble binding agent, the second one is a solution of plant extract from tree barks or gallnuts, while the third one contains both soluble and insoluble phases. This last ink is based on metal (iron) and is produced by a chemical reaction of soluble iron (II) with tannin in aqueous solution. Tracing the transition from writing inks based on carbon pigments (soot or charcoal), common in Antiquity to the iron-gall inks commonly used in the Middle Ages builds a focus of our investigative work at the BAM (Federal Institute of Material Analysis and Testing) [1-5]. With the aim of creating a detailed history of writing black inks, we worked out a non-invasive protocol to collect statistically relevant ink data from dated and localized manuscripts covering a large time span and different geographic areas. The first step of our protocol consists of the screening carried out by means of imaging in the near infrared region. The optical differences between carbon, tannin, and iron-gall inks are best recognized by comparing their response to the infrared light: carbon ink has a deep black colour, iron-gall ink becomes transparent above 1400 nm, and tannin ink disappears at about 750 nm, we have simplified the analysis using a small USB microscope with built-in NIR (940 nm) and UV (395 nm) LED in addition to an external white light source [1]. Comparing the images under white and near infrared illumination, we determine the ink typology by observing the changes in the opacity of the ink. Here, carbon-based inks show no change in their opacity when illuminated with near infrared light, while the opacity of iron-gall inks changes considerably, and tannin inks become transparent. Our own recent finding that mixed carbon / iron-gall inks were quite popular in the late Antiquity and early Middle Ages suggested to return to the conventional method using infrared light in the spectral region 1000 – 1400 nm. The presentation will show the panorama of historic inks and our attempt to follow up the transition of the inks from those based on soot to the iron-gall inks commonly used in the Middle Ages.
