Ius Commune Podcast

In this episode, host and guest delve into the challenges and fascination of late Roman law and codification. Professor Peter Riedlberger—a leading historian of Late Antiquity at the University of Bamberg and principal investigator of two ERC projects (Acts of the Ecumenical Councils and AntCoCo: Understanding Late Antique Top-Down Communication)—explains how imperial constitutions and codices such as the Codex Theodosianus were produced, transmitted, and interpreted.Riedlberger discusses his approach that combines philology, legal history, and digital humanities, revealing how Late Antique laws were both normative texts and rhetorical performances meant to convey imperial authority. The conversation touches on the chaotic reality of legislation, the persistence of repetition and ambiguity even after codification, and the ways his ERC team reconstructs full constitutions from inscriptions, papyri, and manuscripts rather than relying solely on later excerpts.The episode frames codification not as an endpoint but as an evolving process of communication—showing how digital tools like Amanuensis and Cursor are transforming the study of ancient law.

Emilia talks with with Prof. Kaius Tuori about how Roman law served as a unifying force in post-war Europe. Prof. Tuori traces Roman law's role back to German legal scholars exiled in Britain during the Nazi regime. After the war, Roman law's legacy of shared legal principles offered a foundation for reiminaging Europe, both politically and legally.

In this episode, we talk to Dr. Peter Candy, Assistant Professor of Civil Law and Fellow of St. Catherine’s College at the University of Cambridge, about his book Ancient Maritime Loan Contracts (University of Michigan Press), which examines the commercial financing of the maritime trade in ancient Greece and Rome. It’s a period that contains the roots of modern shipping law, finance, insurance, and much more, and makes for a fascinating look at how private law operated in antiquity.Buy Prof. Candy's Book Here: https://press.umich.edu/Books/A/Ancient-Maritime-Loan-Contracts2

In this episode, we explore the project “The Making of Local Legal Cultures under Rome,” featuring an interview with Professor's Yair Furstenberg, from the Hebrew university in Jerusalem. The project examines how communities in the Greek East negotiated their legal identities amid Roman imperial authority, revealing that law was not a vacuum but a contested space where local customs and Roman practice interested. By integrating early rabbinic literature as a key source, the project sheds light on Jewish jurisprudence and its role in provincial law-making. Through a multi-dimensional analysis of various legal traditions, including legal papyrology and Roman law, the project aims to uncover how these local legal cultures expressed agency and self-determination, ultimately contributing to a richer understanding of cultural and political distinctions under Roman rule. Join us for an enlightening discussion on the complexities of law, identity, and power in antiquity.

In this episode, I interview Prof. McSweeney about his book, Priests of the Law.
