Religion was woven into the fabric of Roman society, its visibility ranging from monumental temples to the practice of festival activity. Religious processions, in particular, were carefully choreographed rituals that linked disparate spaces and people together within the cityscape. Despite their acknowledged regularity within the Roman world, our understanding of religious processional movement remains extremely limited. Studies concerning Triumphal, funerary, and circus processions dominate current scholarship due to their greater documentation by the ancient literary sources. These processions, however, formed only a fraction of Roman processional activity. Recent years have seen an increase of scholarship interested in different aspects of processions and movement within the cityscape. In light of this, a reconsideration of the degree to which we can study processions within the archaeological record is warranted. As the record of the performance of processions was primarily held in the memories of those who took part of heard about them, the ways in which they can be studied is challenging. Adopting a theoretical and computer based approach, a critical analysis of the relationship between a procession’s movement patterns and engagement with the urban environment can be studied.

In the last years several web services emerged that manage and make accessible place gazetteers for the archaeologies and historical sciences. By using semantic technologies these gazetteers act as linked data hubs connecting multiple datasets of varying thematic focus and of different structural properties. Just as important as the geo-spatial properties of research objects are their temporal classifications. In this talk we describe a time gazetteer web service that assumes a role similar to that of place gazetteers but for temporal concepts and cultural periods.

The interpretation of archaeological surface survey data is not straightforward. The aim of this paper is to critically evaluate the interpretative potential of the surface survey record in terms, on the one hand of demography and settlement pattern, on the other hand of consumption and changing social patterns of commodities distribution and access, using the microregional ceramic dataset collected during fieldwork in the region of Thugga (Tunisian High Tell). By analyzing rural surface pottery assemblages among settlements pattern and topography, I will show the application of a spatial and quantitative approach to the survey record and discuss its potential and risks. At the macroregional scale, consumption patterns will be considered in a comparative perspective among urban and rural settlements as well as coastal sites and rural hinterland of the Roman Province Africa Proconsularis. The reconstruction of a geography consumption allows a ceramic view on the economic development of the Roman Province and on its integration in the inter-regional and long distance markets.

The detection of textual variants is a crucial step in Classical Philology. It represents both the first stage of collation and the preliminary phase for recognising quotation and text reuse in the indirect tradition. As digital tools can improve the mechanical stage of textual comparison, the interaction between automated process and traditional philological methods is in this case very promising. iAligner performs pairwise intralanguage syntaxbased automatic alignment on Ancient Greek, Latin and English, and it is now being tested on other languages. Texts are aligned at line or sentence level, at any length chosen by the user. They are then converted to vectors of single tokens, and pairwise alignment is performed through Needleman-Wunsch algorithm. Additional languagedependent criteria can be established by the user for further refinement, according to the purpose of the alignment: nonalphabetical characters and diacritics can be ignored, the alignment can be set as case sensitive and Levensthein distance metric can be applied to adjust the tolerance threshold.

A few years ago, scholars of Greek and Latin literature called for a “cyberinfrastructure” that would facilitate a new generation of digital collections - an infrastructure that uses linked open data approaches to organize the myriad of web resources related to classical studies. Already such frameworks are being built on the basis of existing claves, digital transcriptions of texts, and other tools that comprise standards in the fields of Greek and Latin.

A key claim made by Hero of Alexandria in his work Περί αὐτοματοποιητικῆς (On the making of the Automata, hereafter Automata) is that he has improved upon previously described automata, making them more feasible and more easily reproduced in practice. A three-year, Leverhulme-funded project is testing Hero’s devices and his claims. Working from a fresh analysis of the Greek text, the two automata described by Hero are being built, initially in the computer-aided design (CAD) package SolidWorks, and then in the physical world. A primary objective is to determine to what extent the Automata is a technical treatise, exaggeration/self-aggrandisement and/or a jeu d’esprit.

Maya writing is a semi-deciphered logographic-syllabic system with approximately 10,000 text carriers discovered in sites throughout Mexico, Guatemala, Belize, and Honduras (300 B.C. to A.D. 1500). It is one of the most significant writing traditions of the ancient world. As a graphic manifestation of language, writing mediatizes human thought, communication, and cultural knowledge in the form of texts. Deciphering a script allows ideas, values, conceptions, and believes to be reconstructed, and thus permits insight into the memory of past communities. In order to achieve this, the writing system and the spoken language that underlies it must be known. For Classic Mayan, this breakthrough in decipherment has already been achieved; however, in spite of great progress made in recent decades, some 40% of the script’s more than 800 signs remain unreadable even today. One reason for this situation is their lack of systematic attestation. Even in cases in which the signs are legible, texts may still elude understanding, because the Classic Mayan language itself has not survived; instead, it can only be reconstructed through comparison of the 30 Mayan languages documented since European conquest and still spoken today. However, much pre-Hispanic Mayan cultural vocabulary has been lost in the aftermath of European colonization. Consequently, comprehensive documentation and decipherment of the approximately 10,000 extant hieroglyphic texts, reconstruction of the language that they record, and documentation of that language in a dictionary are necessary prerequisites for acquiring a deeper understanding of Classic Maya culture, history, religion, and society.

3D panoramic multi-person localization and tracking are prominent in many applications, however, conventional methods using LiDAR equipment could be economically expensive and also computationally inefficient due to the processing of point cloud data. In this work, we propose an effective and efficient approach at a low cost. First, we utilize RGB panoramic videos instead of LiDAR data. Then, we transform human locations from a 2D panoramic image coordinate to a 3D panoramic camera coordinate using camera geometry and human bio-metric property (i.e., height). Finally, we generate 3D tracklets by associating human appearance and 3D trajectory. We verify the effectiveness of our method on three datasets including a new one built by us, in terms of 3D single-view multi-person localization, 3D single-view multi-person tracking, and 3D panoramic multi-person localization and tracking. Our code is available at \url{https://github.com/fandulu/MPLT}.

Throughout the last decade, network analysis has become an increasingly popular method of archaeological research, but the complexity of the archaeological record poses a fundamental challenge. Data sets can be comprised of hundreds or thousands of entities as well as several types of objects, demanding special caution of the design of such studies. Therefore, an appropriate way of storing and querying data is a crucial first step. For this purpose, graph databases are especially well suited. The storing of data as nodes and edges introduces relationship-based thinking already in the early stages of data preparation and acquisition. For archaeological use-cases, the CIDOC CRM suggests itself as the ontology after which to model the structure of the database. The talk will present a mapping of the CIDOC CRM to the model of a graph database containing Late Bronze Age elite graves and explore possibilities of graph databases to archaeological network analysis in further detail.

In the last few years, we have attempted to reconstruct the Roman transport conditions by modelling travel costs and times with the help of GIS and Network Analysis applications. The main geographical focus of this project was the NE of Hispania. It was necessary devote a significant effort to the gathering, documentation, analysis and digitisation of Roman communications with high precision. With the aim of using these methodology in a much broader geographic frame, the entire Iberian Peninsula, Italy and Britain were analysed with less detailed transport networks . It allows us to discover very interesting patterns. The results of such applications provide us with new information to understand the distribution of commodities, product competition and problems of stagnation in ancient economies such as that of Ancient Rome.

Das Feld der Linguistik ist in den Digital Humanities seit dessen Anfängen von großer Bedeutung. Ob die abstrakten Strukturen der Informationstechnik den Sprachstrukturen besonders leicht nahe kamen, ob die Datenmengen die Verwendung von Computern interessant machten, oder ob hier noch ganz andere Faktoren im Spiel waren, darf eine offene Frage bleiben. Als ein Ertrag der Computerlinguistik stellte sich in jedem Falle heraus, dass das Sammeln von Daten nicht nur mit dem Ziel, ein elektronisches Nachschlagewerk zu erhalten, verfolgt werden könnte, sondern dass durch systematische Weiterverarbeitung und Darstellung der Daten bestimmte, meist quantitative, aber auch strukturorientierte Fragen gestellt werden könnten, deren Ergebnisse dem Forscher Hinweise auf bislang nicht erkannte Phänomene geben könnten.

Throughout Greek and Roman history, naval warfare played a prominent role. Gaining, exerting and contesting sea power was an important characteristic of many a conflict from the Archaic period right down to Late Antiquity; indeed, from the Persian to the Punic wars, contesting control of the sea was often at the very centre of the conflict. Yet despite its importance naval power in general and naval action in particular is extremely poorly understood, and already the most basic questions regarding an ancient naval action – what could and what did actually happen – remain to this day mostly unanswered.

Philology is the aggregate of those practices by which we exploit the linguistic record to engage culture perspectives that are distant from us in time, space, and/or perspective. Whether we are exploiting post-colonial theory, corpus linguistics, or some aspect of the cognitive and brain sciences, we are practicing philology. In the 21st century, we confront the challenge of managing interactions across boundaries of space, language, and culture that are unprecedented in speed and complexity, which each point on the globe now able to interact with any other point in real time. We must think in terms of a World Literature – as Goethe suggested almost two centuries ago – and to do so we must articulate a new philology, one that exploits every possibility of new digital media. Ultimately, we need to establish a sustainable set of evolving cultures – a dynamic Global Culture that provides a voice for many different cultures within it. The field of Altertumswissenschaft has an opportunity to play a fundamental role in this larger process but realizing that opportunity requires a reexamination of what we do, why we do it and for whom.

The study of intertextuality in Classical poetry often presents itself as a specialized case of text-reuse detection: commentaries and other close readings of a work concern themselves with the identification and exegesis of phrases borrowed from earlier texts. Yet it has long been understood that larger-scale, structural parallelisms can also exist between texts (Genette 1997), and that these can provide the context necessary to establish an allusive or intertextual link between two phrases (Wills 1996). Automatic detection of intertextuality must take into account features at various scales: from individual phonemes to larger syntactic units and type scenes.

*ABSTRACT* This seminar will revolve around two Reflectance Transformation Imaging (RTI) projects based at the University of Cologne on ancient Greek texts. The first deals with the Herculaneum Papyri. Preserved through carbonisation when Mount Vesuvius erupted in 79 CE, these papyri constitute the largest surviving ancient library in the world. For over two centuries scholars have sought to unroll and read the c.1800 papyrus scrolls found in the Villa dei Papyri. Recent infrared RTI has resulted in a major leap forward for revealing further writings and providing vital information about the physical structure of the rolls. The second project, “Magica Levantina”, aims to create an edition of Greek magical texts from Cyprus and the ancient Near East. Over 300 texts, dating from c.100-600 CE and comprised mainly of curses and some protective spells, are incised on various metals and gypsum. Material properties, writing technique and poor condition present challenges to legibility that are successfully tackled through the use of visible spectrum RTI. Several themes arise from the case studies presented. The conventional use of the digital image as a resource for interpreting past written meaning will be contrasted with a more active concept of the digital image as constitutive of both past reconstructions and the interpretive process. This latter concept will be developed to argue for greater reflexivity in image data use and increased epistemological awareness of the role of the digital image — whether employed for research on the Classical world or the ancient world more generally.

ABSTRACT How does a researcher or analyst determine whether two records refer to the same person or are related in some other way, and whether other related information refers to both people equally? Starting with three large datasets from the classical world: the Lexicon of Greek Personal Names, an Oxford-based corpus of persons mentioned in ancient Greek texts; Trismegistos, a Leuven-run database of names and persons from Egyptian papyri; Prosopographia Imperii Romani, a series of printed books listing senators and other elites from the first three centuries of the Roman Empire, SNAP:DRGN aims to create a lightweight model to bring this prosopographic and onomastic data together. Web and Linked data technologies offer ways to model and share this information; linking from references in primary texts to, and between, authoritative lists of persons and names. The SNAP project looks to the many prosopographies and onomastica that already exist, initially within the restricted domain of Greco-Roman antiquity, for whom the same questions of identity and provenance apply and asks whether combining these approaches will allow us to create a shared resource for classical scholars who wish to disambiguate their data. SNAP:DRGN is an AHRC-funded project exploring the interlinking data collections of persons (prosopographies), names (onomastica) and person-like entities managed in heterogeneous systems and formats. This paper will explore the background to, and results of, the work. http://hdl.handle.net/11858/00-1780-0000-0024-5F70-E

ABSTRACT The study of the Roman economy is populated by a large number ofsometimes conflicting descriptive models. These models are rarelyformally compared, and many remain untested due to the limited use offormal hypothesis testing methods in Roman studies and the significantdata requirements to enable their use. This paper illustrates how broadpatterns in large archaeological datasets allow for aspects of thesemodels to be tested, and suggests agent-based network modelling as aparticularly fruitful approach for the study of the Roman economy. As an example, this paper presents the Market Economy and Roman CeramicsRedistribution agent-based network model (MERCURY, after the Roman godof commerce). It represents the structure of social networks betweentraders that act as the channels for the flow of commercial informationand goods. MERCURY was created to formally represent and compare twodescriptive models of the functioning of the Roman trade system (PeterBang's Roman bazaar (2008) and Peter Temin's (2013) Roman marketeconomy) and how these give rise to differences in the distributionpatterns of Roman tablewares. The results of experiments using MERCURYare subsequently compared to archaeologically observed tablewaredistribution patterns. The results suggest that, contrary to Bang'shypothesis, limited availability of reliable commercial information fromdifferent markets is unlikely to give rise to the large differences inthe wideness of tableware distributions observed in the archaeologicalrecord. This paper concludes that the study of the Roman economy wouldvery much benefit from embracing computational modelling approachesbecause (i) it forces scholars to consider the comparability ofdescriptive models, (ii) it allows comparison of simulated outputs witharchaeologically observed outputs, and (iii) it allows to map out thegrey zone between extreme hypotheses and refocus our descriptive modelsaway from hypotheses that do not compare favourably with thearchaeological record. http://hdl.handle.net/11858/00-1780-0000-0024-5022-5

ABSTRACT The talk will present an ongoing research project (Γ-project from now) aiming at designing a dynamic grammar of Ancient Greek. Just as many other languages, Ancient Greek is characterized by a complex interplay between its rich morphological features, its wide range of semantic roles and its diverse syntactic functions. The nodes where these three types of features intersect are commonly known as grammar rules. This means that grammatical rules, in sharp contrast to their static presentation in grammar books as well as online grammars can be regarded as the result of many-to-many relationships. To secure its dynamic structure, the Γ-project is constructed around these many-to-many relationships. Exploring these relations, students will acquire Greek language skills, while also acquiring a more profound knowledge of language structures. Hence, the Γ-grammar will be a novel instrument for learning and understanding ancient languages. As the technology of Γ-grammar will be available under a Creative Commons license, a similar application for other (ancient or modern) languages would be conceivable.

ABSTRACT In the last years much effort was put in the construction of digital editions, covering all epochs from antiquity to modern writers. Looking at these digital scholarly editions, a huge variety of methods, presentations and tools has been developed. As digital editions have thus reached a critical mass, we must ask about the quality of the heterogenous digital editions. In this presentation I want to discuss, if and how these digital editions can be compared. Given the example of the Codex Sinaiticus, a catalogue of questions can be adressed to this digital edition.
