• Vita

    Uri Yiftach is Full Professor of Classical Studies at Tel Aviv University. His research combines papyrology, legal history, historical linguistics, and computational methods to study how ancient institutional and technical writing encodes normative, prescriptive, and descriptive meaning across time and genre. A central axis of his work is the interplay between legal unity and pluralism in Greek legal traditions, approached through the linguistic and structural foundations of formulaic writing: the evolution of key terms, the specialization of meanings, and the regional and diachronic adaptation of recurring frames.

    He is the author of The Taxonomy of the Legal Document, a clause-by-clause typology of contractual formulations in Greek papyri from the early Hellenistic to the late Byzantine period, developed as both a classification system and a research tool on the basis of the Synallagma corpus. His current research direction expands from legal language to a general reconstruction of recurrent semantic structures in legal, administrative, and scientific discourse, aiming to model stable, reusable semantic configurations (“cogs”) and to trace their transmission and transformation across centuries, regions, languages, and genres within an ontology-linked, computationally explicit framework.

    The Linguistic Foundations of Greek Legal Traditions

    Greek legal documents from Ptolemaic, Roman, and Byzantine Egypt display a striking degree of formulaic unity in structure and terminology, even while adapting to local contexts. This project investigates the linguistic and structural foundations of that unity and asks how it emerged, how it changed over time, and how it coexisted with regional diversity. As background, it treats legal language as part of a discursive koine: a shared repertoire of stabilized patterns that remains interoperable across settings while allowing local parameterization. A central problem is the uneven record: later material is abundant, but Classical-period evidence is scarcer and fragmented, raising questions about whether later cohesion reflects earlier developments or later standardization. The project builds on a corpus-based inventory of c. 2,000 contractual terms from Egyptian papyri and traces the evolution, usage, and semantic specialization of key terms from Classical through Hellenistic and Roman periods. It then compares patterns across regions and uses indirect Classical evidence (inscriptions, literary and rhetorical texts) to reconstruct earlier legal language. Combining linguistic, philological, and historical methods, it clarifies how unity and adaptability were sustained in multicultural legal environments.
