Z02 is one of the three technically supporting projects at the Centre for the Study of Manuscript Cultures (CSMC). In collaboration with the other two service projects, Z01 and Z03, it aims at bridging the gap between humanities and natural sciences and technology. To that purpose, we set up a laboratory with a range of high-end instruments, most of them mobile, allowing thorough non-destructive analysis of manuscripts. In addition to working on constantly improving the laboratory and the methods of analysis, a substantial part of our activities is dedicated to service, by supporting different research projects conducted at the centre. In this talk, we will present our equipment and the possibilities offered by the different techniques available regarding the different kinds of missions: typology and classification of inks, provenance studies, recovery of faded inscriptions and palimpsests, reconstruction of the history of manuscripts, authentication and dating. We will give a brief overview of our past and ongoing activities in the frame of the second phase of the CSMC. Finally, a selection of projects will be presented in greater detail to highlight the possibilities of our laboratory and the diversity of missions which can be carried out.
Papyrus was in use in the Islamic world until the 11th century and few ink recipes collected from treatises about the art of the books are dedicated to this support. But papyrus was also burnt in order to obtain soot used as an ingredient for a particular type of ink (midād al-qarāṭīs). In this talk I will give an overview of the recipes – in particular those by ar-Rāzī –, their context and transmission in order to evaluate this double nature of papyrus, which is considered at the same time a writing support and a material to be recycled. Moreover, I will discuss what kinds of ink are most likely to be found, according to these literary sources, on Arabic manuscripts and documents written on papyrus and compare them to the typologies mentioned for paper and parchment. These results are the premises of a research project starting at the beginning of 2019, in which a number of dated fragments from several European institutions will be analysed with non-destructive techniques in order to establish a profile of the main writing media used in the early centuries of the Islamic Era.
Ink recipes from the islamic era: Texts, manuscripts, ink reproductions and scientific analyses
(2019)
Ink recipes can often be found in Arabic manuscripts. They may be included in treatises of diverse subjects – from handbooks for secretaries or calligraphers to books on arts and crafts, to alchemical and astrological essays. Recipes can also appear, with or without relation to the main text in the manuscript, in the form of lists or collections or even added in empty spaces as single entries. Why were these recipes written down? Were they used by the many professionals dealing with inks in their every-day work? Or were they part of the literary genre of adab with little or no practical application? To answer these questions a research project was set up: ink recipes have been collected from written Arabic sources, their feasibility has been assessed and some of them have been reproduced. These samples were artificially aged and analysed through an array of analytical techniques, most non-invasive and non-destructive, and the results compared to the data obtained by the application of the same analyses on concrete manuscripts. The codicological characteristics of the manuscripts have also been studied. My aim in this talk is to show how such an interdisciplinary approach could be beneficial for the study of material culture.
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.
