Information for Applicants
About us
Welcome to our information page for applicants! The Cluster of Excellence ‘Understanding Written Artefacts’ (UWA) is an international, cross-disciplinary research project for the holistic study of (hand)written artefacts. UWA is housed at the Centre for the Study of Manuscript Cultures (CSMC), a cross-faculty research centre at the University of Hamburg. UWA’s main objective is to investigate the rich diversity of global manuscript cultures in a comparative way.
Objectives of UWA
-
Creating and promoting a global and holistic framework to map and analyse the diversity of writing cultures
This objective builds on one of the most distinctive characteristics of the cluster’s community, namely our willingness and ability to work across established boundaries and relate highly diverse written artefacts to each other. -
Considering ethical challenges and the impact of digital media transformations faced by scholars working with written heritage
Working with and on written artefacts brings up numerous ethical issues. In UWA II we will focus on three areas in particular: critically revisiting the notion of ‘non-invasive’ material analysis (see for instance CMU 2 Ethical Analysis); condensing our experience in projects for the safeguarding of written heritage into programmatic guidance (see for instance CMU 4 Navigating Crises); and assessing how the shift towards researching written artefacts on the basis of digital reproductions, accelerated by the pandemic, has had an impact on research practices and agendas in the Humanities (see for instance CMU 6 Digital Twins). -
Rethinking the divide between handwriting and printing to reconceptualise traditional typologies of writing media
In UWA II, we will integrate ‘imprinted’ writing into our concept of ‘written artefact’, in particular via CMU 5 Imprinted Handwriting. We argue that many techniques for mechanically reproducing content (including the use of seal matrices, coin dies, moulds, punches, woodblocks and lithographic stones) must also be considered integral parts of humanity’s history of handwriting. -
Foregrounding the processes of adaptation and transmission of written artefacts and writing practices across time and space
UWA II will highlight the shifting and inherently dynamic status of individual written artefacts by studying processes of production, adaptation and transmission. On the one hand, UWA II foregrounds the flexibility of material and technological choices (see for instance CMU 1 Material Choices). On the other hand, our focus on transmission emphasises that written artefacts move through volatile contexts (see for instance CMU 3 Phased Transmission). -
Writing entangled histories of written artefacts and writing practices, relying strongly on new methods for provenancing
In the course of UWA I we have predominantly worked to identify and bring into communication comparable phenomena that had hitherto been researched in different, often mutually incommensurable, scholarly traditions. UWA II will ask to what extent such phenomena share not only material similarities, but also histories. We will collaboratively work on this especially in the PGs, many of which are designed to determine by cross-cultural research how and to what extent writing materials, techniques and practices were connected and modified while being circulated across space and time. -
Refining and developing methods for the material analysis of written artefacts, especially for provenancing and enhancing legibility
UWA II will develop new methodological approaches for our material analysis toolkit. This will allow decisive advances in enhancing the legibility of previously inaccessible content and expanding the potential of material analysis for provenancing written artefacts in terms of their origin and subsequent life cycles. Our cooperation with DESY will, for instance, explore possibilities for new Computed Tomography scanning instrumentations for written artefacts. -
Tailoring computational and artificial intelligence-based approaches for the study of written artefacts
UWA II will tailor AI approaches to the cluster’s research agenda. We will employ and refine multimodal machine-learning techniques to uncover patterns across the various modalities present in our expanding dataset including text, image and material analysis data. This also involves designing sustainable data management for machine-learning and AI-based information retrieval. Additionally, we will develop intuitive human-machine interfaces to improve accessibility and usability for the research community. -
Safeguarding of written heritage
UWA seeks to become a platform for discussing potential realignments of research agendas with collection care and management practices for written artefacts. With our experience in running projects for safeguarding written heritage worldwide, especially in the context of crises, we will use our expertise in material analysis, digitisation and navigating cultural contexts to be a leading institution in research-integrated care and management practices for written heritage collections, including preventive and remedial conservation.
Our paradigm and framework can be summarised by our concept of the written artefact (WA), defined as ‘any artificial or natural object with visual signs applied by humans’. This way, our global perspective encompasses all objects carrying handwriting, from the beginning of writing to today’s digital age, including clay tablets, papyrus sheets, inscribed rocks, wooden tablets, palm-leaf pothis, parchment codices, wall graffiti, digital twins of WAs and many more. This comprehensive understanding of humanity’s handwritten heritage enables our scholarly community to study the material dimensions of WAs in relation to their content in order to provide a fuller understanding of how societies have shaped writing and how societies, in turn, have adapted writing to their needs.
The cluster’s research has overcome long-established academic boundaries between regions (especially between Europe and ‘other’ world regions), periods (such as between Antiquity, the Middle Ages and the modern period) and disciplines (between the Humanities, Natural Sciences and Computer Science). UWA brings together more than 150 researchers from over 40 academic disciplines, currently working on over 60 research projects; since 2019, more than 50 projects have been completed.
UWA has been funded by the German Research Foundation (DFG) as part of Germany’s Excellence Strategy since 2019, with substantial additional funding by the Free and Hanseatic City of Hamburg and the University of Hamburg (UWA I, 2019–2025). UWA’s second funding phase UWA II will start in 2026 and we are delighted that new researchers will join us in this exciting phase.
FAQ – Frequently Asked Questions
How do I find a supervisor (doctoral researchers)?
A preferred supervisor from the cluster UWA must be named in the applicant’s cover letter. You will find here a list of potential supervisors. For the application it is NOT necessary to already have contacted potential supervisors.
Can I apply for a doctoral position with an ongoing PhD project?
PhD researchers with ongoing projects are also eligible to apply, but only during the first year of their PhD. Supervisors external to Universität Hamburg can be members of the supervisory committee. The first supervisor has to be from UWA.
Can I apply for both postdoctoral researcher (E13) and research group leader position (E13/E14), if I’m not sure?
Yes, you can, but please apply separately for both positions.
What is meant by ‘literature review’ in the project proposal?
The literature review included in your project proposal should provide an overview of the current state-of-the-art research related to the topic of the proposal. This is also known as Literature Survey or State of the Art Review. If the applicant has any relevant publications on the subject, these should certainly also be acknowledged. All referenced literature should be listed in the bibliography.
Does the bibliography count towards the 5-page limit?
No, the bibliography does not count towards the 5-page limit of the project proposal.
How do I calculate the budget in my project proposal? (Postdoctoral researchers)
In your budget plan please calculate your expected project costs per year, especially expenditures such as field trips and conference participation. You do NOT have to calculate your salary costs.
How does my project fit into UWA’s research programme?
Applicants propose a research project (Independent Research Project, IRP) as specified in the corresponding call, with which they contribute to UWA’s research programme and to one or more of its general objectives shown above. Once accepted, all researchers will become involved in Project Group (PGs) and Concepts and Methods Units (CMUs), according to their fields of expertise. However—and this is an important point—your IRP does not have to be a perfect fit for a PG or CMU. You are free to design a project that is independent and original, even if it does not neatly fall into one of those pre-existing structures.
Where does collaboration take place?
Primarily, UWA researchers are working self-responsibly in their Independent Research Projects (IRP). IRPs should be open to cross-disciplinary collaboration, for which UWA provides a range of fora including,
- Research groups like PGs (Project Groups), CMUs (Concepts and Methods Units) and working groups
- Events and activities in the Graduate School (for doctoral researchers)
- The UWA laboratory system for written artefact analysis
- Research and Study Days
- Workshops, conferences and lectures etc.
Doctoral researchers will join an existing PG; postdoctoral and advanced postdoctoral researchers will join an existing PG and CMU; advanced postdoctoral researchers are subsequently expected to develop their own PGs.
Is remote work possible?
With its many different disciplines and research projects on various writing cultures, the cluster’s holistic approach to understanding written artefacts depends on face-to-face collaboration and participation. Therefore, remote work is not an option, though up to two home office days per week are permitted.
UWA II Structure
With the transition to UWA II, UWA’s research structure will change. UWA I’s research has been structured in an average of 65 individual and independent three-year research projects, organised in 11 research fields. UWA II will be structured in a new way with Independent Research Projects (IRPs), smaller Project Groups (PGs) and Concepts & Methods Units (CMUs):
Independent Research Projects (IRPs)
Independent Research Projects (IRPs) are specialised disciplinary-oriented projects on doctoral, postdoctoral and professorial levels. They often focus on individual writing cultures, even specific written artefacts. IRPs have their own budget.
Ideally, applicants will propose IRPs which contribute to UWA’s research programme and to one or more of its general objectives shown above. IRPs do not have to be a perfect fit for a PG or CMU. Applicants are free to design a project that is independent and original, even if it does not neatly fall into one of those pre-existing structures.
Concepts & Methods Units (CMUs)
The six Concepts & Methods Units (CMUs) in UWA II are groups of c. 15 professorial and postdoctoral researchers. The CMUs will primarily take on cross-cutting conceptual and methodological tasks in pursuing UWA’s objective of building a global and holistic framework. To this end, they will produce programmatic outputs, including joint articles, Occasional Papers, guidelines and protocols. The CMUs’ programmatic outputs will feed into the work of the PGs and IRPs and, vice versa, the empirical studies of the IRPs and PGs will inform the work of the CMUs. Likewise, members of a CMU will belong to different PGs and vice versa. Where appropriate, individual PGs and CMUs will interlink through collaborative activities, such as joint Study Days.
CMU 1: Material Choices
CMU 1 will reframe UWA’s fundamental commitment to a material-based approach, highlighting that the materials employed in producing WAs are rarely without alternatives. Materialities of writing usually exist in the plural, hence the usage of one set of materials rather than another requires explanation. CMU 1 thus focuses on the production of WAs as a vital aspect of their lifecycle. It highlights the importance of material choices within WAs cultural and historical contexts and considers both technological options and cultural capabilities that may influence selection of materials when producing WAs.
Key questions include how originators – understood as agents responsible for producing WAs – selected from various available materials and existing modes of visual organisation, while considering alternatives and pragmatic factors such as resource availability and cost. Material options are highly diverse across writing cultures and it is against this background that CMU 1 explores the ways in which symbolic meanings and social significance impact decisions in WA production. It concentrates on two main axes, 1) the human agents involved in this production, e.g. considering their social, political, and religious backgrounds, technical and technological knowledge, the attribution of value to certain materials etc., and 2) the writing materials used, including the availability of writing materials and (perceived) material properties that may have influenced choices in WA production.
CMU 2: Ethical Analysis
UWA is deeply aware of the ethical implications of its research and the fact that its methods must be in line with the highest ethical standards. We continually reflect upon the fact that studying written heritage is fraught with complex moral conundrums and relies on difficult considerations and choices. CMU 2 will enlarge on one specific topic that has repeatedly emerged in the work of the cluster’s Ethics Working Group and that demands a dedicated forum, the ethics of natural science-based material analysis of WAs. It deals with the fact that the material analysis can have significant consequences for the artefacts themselves. As the artefacts we analyse embody cultural heritage from regions across the world, our methods – even if applied with the best of scholarly intentions – may be inappropriate for the communities who own them.
CMU 2 will rethink the simplistic dichotomy between destructive/invasive vs non-destructive/non-invasive analysis. Against the background of a conflicted history of material analysis in WA studies, it seeks to increase awareness of the changing nature of ethical and sustainable standards over time. Ethical Analysis, hence, will be organised around three main axes, 1) Stress Level Scale (the potential invasiveness and destructivity of any analytical method), 2) Decision-Making processes (avoiding one-size-fits-all proposals and promoting case-sensitive assessments) and 3) Sustainability (avoiding harm to WA in the long run and considering ecological side effects).
CMU 3: Phased Transmission
Within UWA II’s overall attempt to enrich the study of WAs as material objects by highlighting their flexibility and adaptability, CMU 3 will develop an analytic framework for understanding the life cycles of WAs in terms of content, materiality and context.
Dynamic processes of recontextualisation, reappropriation and reconfiguration are inherent parts of a WA’s life cycle following its initial production phase. Transmission of WAs can thus be understood as a series of – often transformative – events and phases that leave their traces on the WA and create layers of material, significance and context. What a WA is considered to ‘be’ at different moments of its existence is determined by its previous transmission. A comprehensive approach to a WA, its biography and its accumulated cultural significance hence necessitates attempts to trace and reconstruct those (material) marks of transmission that have become an integral part of the object.
Accordingly, CMU 3 will conceptualise the biographical phases of WAs, with special attention to moments of change. We will put centre stage 1) the various forms of caring for WAs in their subsequent life cycles; 2) phenomena of destruction or degradation; 3) and the scholarly retrieval, de- and recontextualisation, and examination which leave their own traces on the object and/or within its context.
CMU 4: Navigating Crises
With our long-standing commitment to working on the ground with local communities worldwide, UWA has developed an acute awareness of local emergencies. The transmission of WAs frequently occurs in contexts of crises, as have become ever more obvious in the course of the projects managed by UWA’s Cultural Heritage Unit. Some recurring fundamental questions faced by these projects have laid the foundation of CMU 4: What course of action should be taken when research is affected by conflicting pressures from governments and civil societies? How should the differences between emic and etic collection care and management practices be negotiated? How do we reconcile our ethical principles about collection care and management with those of our partners?
CMU 4 will create a platform to address these issues in order to equip UWA II to navigate crises, both conceptually and practically. Three axes of inquiry will help us implement our task: 1) formulating a definition of crisis and a conceptual typology of dangers to WAs; 2) developing checklists for assessing the levels of endangerment and selecting appropriate methods of safeguarding; 3) developing low-cost and easy-to-handle techniques of preventive and remedial conservation, preferably using locally available materials and integrating local knowledge.
CMU 5: Imprinted Handwriting
The concept of ‘written artefact’ has opened up a space for integrating the study of hitherto discrete classes of handwritten objects, such as codices, scrolls, leporellos, tablets, stelae and graffiti walls. UWA II leverages this potential for further integration: CMU 5 will rethink established dichotomies between handwritten and printed artefacts, exploring how the practices of handwriting and its mechanical reproduction – ‘imprinting’ – evolved in a continuous interplay of mutual influence, shaping and transforming one another.
The aim is to highlight that most tools for mechanical reproduction of writing were created through handwriting practices, and that what has been produced through imprinting is decidedly part of exploring the world of handwritten artefacts. Our approach is not limited to carving woodblocks or preparing moulds for casting inscriptions – imprinting encompasses a wide range of materials (e.g., clay, wax, metal, stone, papyrus, paper, parchment) and media (seal matrices, coin dies, moulds, punches, types, woodblocks, lithographic stones, copperplates etc.) from all regions and periods of human history.
CMU 5 aims to develop concepts and methods that enable a systematic study of how the practices and functions of handwriting and imprinting are intertwined and embedded in one another. This comprises two axes: 1) reconceptualising imprinted artefacts as witnesses to handwriting practices; 2) understanding the interconnections in the design, production and consumption processes of handwritten and imprinted artefacts.
CMU 6: Digital Twins
At a time when the practices of handwriting and production of handwritten artefacts are seemingly losing their long-unquestioned role at the heart of human practices of transmission of knowledge, scholars are turning to the study of these same practices. Paradoxically, we do this increasingly by means of digital reproductions and other digital tools. CMU 6 will reflect and conceptualise how the increasing availability of different digital reproduction techniques and their products – ‘digital twins’ of WAs – has shaped, and is continuing to shape, how we conduct research in the digital age.
We employ the term ‘digital twin’, a term first established in engineering, at the centre of a cross-disciplinary discourse about digital reproductions as epistemic tools. We will ask how they are produced, made available and used and will explore the ways they can, and cannot, substitute for research on and with the originals.
The CMU’s work centres around three axes: 1) How digitisation affects what objects are visible and available to scholars; 2) We will consider digital reproductions as part of a longer history of using ‘twins’ of WAs in research, including, for instance, engraving, photography, microfilming, xerox-copying, squeezes, rubbings; 3) CMU 6 will systematically reflect on how our encounter with digital twins has refashioned our perception of the actual material objects. While digital images pretend to be authentic impressions of the artefacts, they are themselves often carefully constructed and optimised digital files.
Project Groups (PGs)
Project Groups (PGs) in UWA are small and versatile cross-disciplinary teams, including professorial, postdoctoral and doctoral researchers. They work on specific case studies and on new topics and materials that emerge in particular as a result of bottom-up cross-disciplinary interaction. The duration of the PGs, running typically for two to four years, depends on their research goals and planned output.
UWA II will start with a set of PGs, developed by our researchers over the last year. They exemplify the cluster’s range of heuristic approaches, contribute to reaching UWA II’s objectives and provide innovative and inspiring fora for incoming early career researchers.
Below, you will find short abstracts of some selected PGs that will be established with the start of UWA II.
PG Turning Rock into Pixels: The Jewish Cemetery Altona
PG Writing in Colours
The Project Group Writing in Colours focuses on the significant role of colours in written artefacts (WAs) and their influence on reader engagement, examining these aspects from symbolic and pragmatic perspectives. The group plans to study the use of colours in creating visual and spatial hierarchies, emphasising concepts and conveying values within the Egyptian, Greco-Roman and Near Eastern contexts between the Bronze Age and the Early Middle Ages. They intend to compile a representative corpus of coloured WAs, exploring various spatial and social settings, time periods, and manufacturing methods, to understand the contextual choices of colours made in different environments like religious, domestic, and public spaces. The PG will utilise cross-disciplinary methods, including archaeological, epigraphic, and papyrological research, Archaeometry, Mineralogy, and Chemometrics. Experimental archaeology will play an essential role in various project activities, including replicating ancient pigment and dye recipes. Key outputs from the PG will include an exhibition and a detailed database that categorises pigments and dyes, enhancing existing databases with specific features for this purpose.
PG Written Artefacts and the Body
This Project Group focuses on the relation between the materiality of WAs and the human body. We examine how the scribe’s physical presence and the corporeal act of inscription impacts WAs from three angles: expressive, normative, and objective. The expressive aspect considers how a scribe’s physical condition influences the material features of WAs. The normative perspective looks at conventions – as benchmarks for specific cultural writing practices across time – that govern the scribe’s posture, scribal techniques, and writing habits. The objective element explores situations in which the body becomes an integral component of WAs.
Given the lack of a comprehensive scholarly approaches integrating body-related discourses and writing practices in WA studies, we investigate scribal and bodily practices in global contexts through emic and etic lenses, utilizing case studies and kinematic models. Our three-year program will result in a co-edited volume providing a cross-disciplinary framework for studying corporeality and WAs and will make use also of knowledge exchange formats emphasizing bodily techniques and abilities involved in the production of WAs.
PG Parchment Panomics: A Holistic Approach to Understanding and Conserving Parchment Manuscripts
In cooperation with the Kairouan Manuscript Project and the Tunisian National Heritage Institute’s National Laboratory for the Preservation and Conservation of Parchment and Manuscripts, this PG will explore the material life cycles of parchment manuscripts from the former library of the Grand Mosque in Kairouan, Tunisia. The PG will advance methods of material analysis, gain insight into the historical context of a specific corpus of WAs and contribute to their conservation. For this aim it will employ a combination of minimally invasive omics approaches, including DNA, protein, metabolite, elemental, and microbiological analyses. Combined with codicological, philological and historical research, this will allow conclusions on individual artefacts’ provenance and life cycles. The PG’s holistic approach of integrating humanities and innovative scientific analyses will thus shed new light on the Kairouan collection and offer a more detailed description of parchment-writing’s material ecologies. The PG’s work will also contribute to refining conservation techniques, thereby increasing the artefacts’ chances of survival, notably by endeavouring to understand the factors contributing to parchment decay, including environmental conditions, historical production and conservation practices.
PG Gleaming Words: Cultural Interaction in Eurasian Golden Plate Inscriptions
The Project Group Gleaming Words investigates the cultural and historical significance of writing on golden plates across Eurasia, tracing their diffusion from ancient Mesopotamia and Egypt through the Mediterranean and eastwards to Persia, South, East and Southeast Asia. Easily repurposed and thus rarely preserved within individual cultures, these plates nevertheless testify to transregional encounters and entanglements in elite material choices and conspicuous consumption. The Project Group delves into how evolving cultural perceptions of golden plates, such as numinosity and sumptuousness, shaped material choices across regions and determined their use in ritual and administrative contexts, oscillating between magico-religious and diplomatic practices. The Project Group aims at fostering cross-disciplinary dialogue across Humanities and Natural Sciences, spanning all relevant fields from Archaeometry to Vietnamese Studies, combining historical, philological and scientific analyses while promoting minimally invasive approaches to the study of production, provenance and dating. Planned outcomes include an online lecture series and a collaborative publication mapping the touchstones, modalities and symbolic values in the transmission of these WAs.
PG Written Artefacts for Staging
The Project Group examines how WAs have historically been employed to facilitate and document performative events like ceremonies, musical and theatrical performances. The group explores the production, revision, and reproduction of these artefacts in relation to visual, auditory, and other sensory elements. Key areas of study include the WA’s role in visualising performance spaces and recording sensory manifestations, focusing on initial notes of ephemeral activities, the evolution of artefacts over time with secondary layers, and the dynamic feedback loop between WAs and staged events. For deeper analysis of how historical WAs influenced and were influenced by performances, the PG will work with digital modelling and experimental staging. The PG will feature collaborative classes and two workshops, culminating in published proceedings with a comprehensive introduction.
PG Navigating Multigraphic Written Artefacts
This Project Group advances UWA’s commitment to digital innovation by utilizing AI and computer vision to enhance the study of multigraphic WAs, which include multiple sign systems like scripts and pictorial elements. Focusing on visual organization, the group aims to improve accessibility and analysis of large digitized cultural collections. Three case studies will demonstrate AI’s potential: analyzing French medieval Bible moralisée manuscripts, classifying subject-based Islamic manuscripts from West African digital archives, and navigating a vast archive of German-Jewish images at the National Library of Israel. These studies will explore how visual elements are organized, map large corpora, and facilitate access to uncatalogued collections. Researchers will identify unique patterns for each study and analyze their visual, spatial and semantic relationships across each collection. Outcomes include novel AI approaches evaluated on vision-language datasets derived from the aforementioned studies, an interactive visual interface for engaging with the developed approaches, and several articles on the developed methods, created datasets, and explored case studies. This collaboration between humanities and computer science aims to establish a new model for exploring intricate manuscript collections.
PG Materiality and Textual Transmission
The Project Group investigates the impact of material features on the history of transmission of texts, merging text-focused approaches with material analysis to enhance philological studies. The group focuses on ‘catalysts,’ material features that trigger changes in derivative texts, aiming to redefine and broaden the Europe-centric, codex-focused approach by incorporating global script traditions, including Armenian, Arabic, and Chinese, among others. The PG’s broader objective is to establish a global framework for identifying material catalysts in textual criticism, enriching philological discourse with non-textual criteria such as material attributes of WAs. Collaborating across disciplines, the group leverages AI, particularly large language models, alongside ink analysis and computational palaeography, to explore manuscript relationships beyond traditional methods. The PG will develop a working definition and taxonomy of catalysts, supported by case studies and a workshop on catalyst typology. A handbook featuring a theoretical introduction and comparative chapters on catalyst categories will be produced, offering a new methodological paradigm for philology and textual criticism.
PG Writing the Family: Genealogical Written Artefacts in Africa, Asia and Europe
The Project Group Writing the Family seeks to advance the cross-cultural study of genealogy as a scholarly field. The group emphasizes the role of handwriting in shaping social realities, particularly highlighting how genealogical writing impacts the imagination of family and kinship structures. The PG aims to provide a comparative analysis of the diverse types and materials of genealogical WAs across cultures, addressing a gap in existing scholarship which often studies such artefacts in isolation. While the family tree is well-documented, particularly in Europe and Islamic contexts, other genealogical forms remain less explored. This PG highlights how culturally sanctioned genealogical inscriptions influence perceptions of social groups and the representation of gender. The PG plans to integrate diverse genealogical practices, including epigraphic, manuscript, text-based, and diagrammatic forms, into a unified scholarly perspective. Through an international workshop and subsequent publications, the group will examine the materiality and socio-cultural functions of genealogical writing, ultimately focusing on narrative and non-diagrammatic genealogies in a subsequent research phase.
PG Provenancing Plant-Based Writing Supports
The Project Group aims to advance understanding of the origins and historical transmission of plant-based writing materials like paper, palm leaves, and papyrus. By employing advanced material-science methods, the group addresses the challenges of determining the provenance of these materials. With a focus on Asian Highland and Southeast Asian manuscripts, the PG plans to develop minimally invasive scientific techniques for profiling such materials. This involves the integration of various cutting-edge methods in microscopy, spectroscopy, microbiology, and data analysis, alongside traditional disciplines like botany and palaeoecology, along with collaboration with DESY for Small and Wide-Angle X-ray Scattering. Results will be cross-referenced with codicological, palaeographical and philological data, contributing to the creation of a comprehensive Atlas mapping the historical and geographic distribution of these writing supports. The outcomes will be shared through publications in international journals and at two dedicated workshops, highlighting advances in material provenancing and the reconstruction of the complex biographies of these materials-based WAs.
