Cuneiform tablets appertain to the oldest textual artifacts used for more than three illennia and are comparable in amount and relevance to texts written in Latin or ancient Greek. hese tablets are typically found in the Middle East and were written by imprinting wedge-shaped impressions into wet clay. There is an increasing demand in the Digital H...
Seals and sealings were widely used in Neopalatial Crete, primarily in community-wide administrative systems to manage the movement and storage of goods, but also to secure or control channels of intra-site communication using parchment documents. The main principle of this monitoring process was the use of the seal impression as an ‘indexical’ sig...
The Corpus of Minoan and Mycenaean Seals (CMS) in Heidelberg contains records of approximately 12.000 ancient seals and seal impressions. The study of the seals, their engraved motifs, and sealing practices gives valuable insights into the social, political and economic organization of Aegean Bronze Age societies. A key research question is whether...
Clay tablets are the oldest handwritten documents using the cuneiform script named after the wedge shaped imprints of a rectangular stylus left in their surface. Therefore the most suitable documentation technique is 3D acquisition using e.g. structured light. The tablets are heterogeneously shaped and may contain damage in varying degrees. Convolu...

In Bronze Aegean society, seals played an important role by authenticating, securing and marking. The study of the seals and their engraved motifs provides valuable insight into the social and political organization and administration of Aegean societies. A key research question is the determination of authorship and origin. Given several sets of s...
The number of known cuneiform tablets is assumed to be in the hundreds of thousands. The Hilprecht Archive Online contains 1977 high-resolution 3D scans of tablets. The online cuneiform database CDLI catalogs metadata for more than 100.000 tablets. While both are accessible publicly , large-scale machine learning and pattern recognition on cuneifor...
Archaeological research into Aegean sealings and sigils reveals valuable insights into the Aegean socio-political organization and administration. An important question arising is the determination of authorship and origin of seals. The similarity of sealings is a key factor as it can indicate different seals with the same depiction or the same sea...
Increased use of 3D digitization methods leads to large numbers of 3D models with script like cuneiform tablets, temple wall inscriptions from the Mayan empire and Minoan and Mycenaean seal imprints. Analyzing and in particular comparing those objects in our projects is a core challenge for robust symbol-spotting and transcription of ancient script...

Deciphering the Maya writing is an ongoing effort that has already started in the early 19th century. Inexpertly-created drawings of Maya writing systems resulted in a large number of misinterpretations concerning the contents of these glyphs. As a consequence, the decryption of Maya writing systems has experienced several setbacks. Modern research...
Libraries, archives and museums have vast numbers of objects with Script in 3D like inscriptions, coins and seals, which provide valuable insight into human history. Especially cuneiform tablets provide access to information about more than three millennia before the birth of Christ. As these clay tablets require an extensive autopsy for transcript...
Cuneiform scripts constitute an immense source of information about ancient history, dating back almost four thousand years. Documents were written by imprinting wedge-shaped impressions into wet clay tablets, and current scholarly practice typically transcribes the resulting markings by hand with ink on paper. This work develops algorithmic method...
Documents written in cuneiform script are one of the largest sources about ancient history. The script is written by imprinting wedges (Latin: cunei) into clay tablets and was used for almost four millennia. This three-dimensional script is typically transcribed by hand with ink on paper. These transcriptions are available in large quantities as ra...

Motivated by the increasing demand for computerized analysis of documents within the Digital Humanities we present an approach to automating handwritten cuneiform character recognition on vectorized cuneiform tablets. Cuneiform is one of the oldest handwritten scripts used for more than three millennia. In previous work we have shown how to extract...
In the Digital Humanities, text sources can be digitized using various methods resulting in different data representations of related documents. This presents an increased challenge for clay tablets with cuneiform script, which is one of the oldest scripts written by hand, used in the ancient Middle East for more than three millennia. Using a 3D-Sc...

German title: ErKon3D – Erschließung und Kontextualisierung von
ägäischen Siegeln und Siegelabdrücken mit 3D-Forensik
funded by the German Ministry of Education and Research (BMBF) within the eHeritage II program.
The project is jointly lead together with Prof. Diamantis Panagiotopoulos, Institute for Classical Archaeology at the Zentrum für Altertumswissenschaften (ZAW) and the FCGLab at the IWR.
Abstract (in German): Die Siegel der Ägäischen Bronzezeit in ihren unterschiedlichen Bedeutungszuschreibungen als Amulette, Prestigeobjekte und Verwaltungsinstrumente erfüllten ihre Funktionen an der Schnittstelle von Religion, Ideologie, Gesellschaft und Wirtschaft. Wesentliche Aspekte dieses Fundmaterials, das seit Jahrzehnten im Mittelpunkt der wissenschaftlichen Aufmerksamkeit steht, wurden bereits im Rahmen des Corpus der Minoischen und Mykenischen Siegel (CMS) vorgelegt, das in Marburg gegründet wurde und nach seiner Verlegung nach Heidelberg im Jahr 2011 als aktive Forschungsstelle fortgeführt wird. Ziel des geplanten Vorhabens ist es, das im Rahmen des CMS entstandene Archiv von modernen Plastilin- und Silikonabdrücken durch die Implementierung neuester Methoden der 3D-Forensik zu erschließen. Letztere sollen nicht nur als Visualisierungs-, sondern in erster Linie als nachweisführendes Instrument genutzt werden. Das Projekt gliedert sich in drei Arbeitsfelder, in deren Mittelpunkt jeweils eine innovative archäologische Fragestellung steht. Durch die fachwissenschaftliche Erschließung und digitale Bereitstellung eines repräsentativen Teils dieser Archivsammlung sollen der hohe wissenschaftliche Wert von archivierten ‚Duplikaten‘ demonstriert und greifbare Erkenntnisse geliefert werden – ohne Autopsie der weltweit verstreuten Originale. Die geplanten Arbeiten sind daher weitgehend frei von speziellen orts- und zeitabhängigen Eigenarten von Siegeln und Siegelabdrücken und ermöglichen damit den Einsatz im weiten Bereich der Bibliotheken, Archive, Museen und Sammlungen.
As an extension to the GigaMesh Software Framework we are developing methods to search for cuneiform charters as symbols i.e. graphical elements. This includes symbols extracted from 3D-models, retro-digitized manual drawings and digital manual drawings sharing the XML-based Scalable Vector Graphics (SVG) format.
The FCGL is a Junior Research Group (JRG) established within the Zukunftskonzept (institutional strategy) of the 2nd German University Excellency Initiative. This concept has the general goal to improve the understanding of complex material, cultural and social topics. The FCGL matches this vision and bridges the well-established fields of the Computational Sciences and the Forensic Sciences by collaborative development of new methods to answer questions arising from Humanities and Life Sciences.
As the forensic science is the scientific method of gathering and examining information about the past, several research fields such as archaeology, assyriology, geology, palaeography and many more share this aim and the methods of the evident task of law enforcement. The remainders of the past are often fragmented objects with three-dimensional hints about their meaning. These hints are represented as geometric features, which range from tool marks, weathering traces, fingerprints to imprinted characters. Even within the landscape evidence of long past human activity can be found as very unobtrusive changes to the natural topology of terrain. Furthermore additional dimensions representing e.g. color or reflectivity have to be included to fully understand the meaning of an object, which are increasingly digitized for virtual autopsy. Methods from Computer Vision and Computational Geometry can assist virtual autopsy by providing additional means of visualizations and allows for objective quantification and extraction of meaningful features.
