Pagan rhetor, (Neo-)Platonist philosopher, Christian theologian This collection of essays is devoted to the rhetoric, Neoplatonic philosophy, and Christian theology of Marius Victorinus, a mid-fourth-century professor of rhetoric and philosopher who converted to Christianity late in life. Scholars from eight different countries, some of whom have not previously published in English, reflect on debates about his writings and theological development. These topics include Victorinus's deployment of philosophical sources for trinitarian theology, possible connections in his work to Origen, Augustine, Plotinus, Porphyry, and Gnosticism, as well as his contributions to Latin rhetoric and dialectic. Contributors include Jan Dominik Bogataj, Michael Chase, Nello Cipriani, Stephen A. Cooper, Volker Henning Drecoll, Lenka Karfíková, Josef Lössl, Václav Němec, Thomas Riesenweber, Guadalupe Lopetegui Semperena, Miran Špelič, Chiara O. Tommasi, John D. Turner, and Florian Zacher. The chapters in this volume are of great interest to students of late antique philosophy, Christian theology, and Latin rhetoric.

This volume, the first one dedicated to the ancient scholia to Cicero's speeches, analyzes them from different angles and positions them in the broader context of late antique commentaries and learning.

This Element examines how the Western philosophical-theological tradition between Plato and Aquinas understands the relation between God and being. It gives a historical survey of the two major positions in the period: a) that the divine first principle is 'beyond being' (Example Plato, Plotinus, Pseudo-Dionysius), and b) that the first principle is 'being itself' (Example Augustine, Avicenna, Aquinas). The Element argues that we can recognize in the two traditions, despite their apparent contradiction, complementary approaches to a shared project of inquiry into transcendence.

In 2021, a previously unknown treatise by Porphyry of Tyre, which has been preserved in a Syriac translation, was made available to historians of philosophy: Porphyry, On Principles and Matter (De Gruyter, 2021). This text not only enlarges our knowledge of the legacy of the most prominent disciple of Plotinus but also serves as an important witness to Platonist discussions of first principles and of Plato’s concept of prime matter in the Timaeus. The aim of the present volume of collected studies is two-fold. On the one hand, it brings up an update to the state of the art of our knowledge of Porphyry’s philosophy and of his role in the transmission of the earlier philosophical materials, especially those of the Middle Platonic works. On the other hand, it focuses on the questions of the reception of Porphyry’s legacy, both by Greek and Latin Platonists (with special interest in Calcidius) and by Christian Oriental authors (with particular focus on the Syriac tradition). The primary audience of the book will be scholars and graduate students in ancient and late ancient Greek philosophy, Orientalists and scholars interested in the Christian reception of Greek philosophy, in the studies of the Christian Orient, as well as in Greek, Latin, and Syriac philology.

Augustine of Hippo (AD 354-430) studied and taught rhetoric for nearly two decades until, at the age of thirty-one, he left his position as professor of rhetoric in Milan to embark upon his new life as a Christian. This was not a clean break in Augustine's thought. Previous scholarship has done much to show us that Augustine integrated rhetorical ideas about texts and speeches into his thought on homiletics, the formation of arguments, and scriptural interpretation. Over the past few decades a new movement among scholars has begun to show that Augustine also carried rhetorical concepts into areas of his thought that were beyond the typical purview of the rhetorical handbooks. In Rhetorical Economy in Augustine's Theology, Brian Gronewoller contributes to this new wave of scholarship by providing a detailed examination of Augustine's use of the rhetorical concept of economy in his theologies of creation, history, and evil, in order to gain insights into these fundamental aspects of his thought. This study finds that Augustine used rhetorical economy as the logic by which he explained a multitude of tensions within, and answered various challenges to, these three areas of his thought as well as others with which they intersect-including his understandings of providence, divine activity, and divine order.

Luigi Gioia provides a fresh description and analysis of Augustine's monumental treatise, De Trinitate, working on a supposition of its unity and its coherence from structural, rhetorical, and theological points of view. The main arguments of the treatise are reviewed first: Scripture and the mystery of the Trinity; discussion of 'Arian' logical and ontological categories; a comparison between the process of knowledge and formal aspects of the confession of the mystery of the Trinity; an account of the so called 'psychological analogies'. These topics hold a predominantly instructive or polemical function. The unity and the coherence of the treatise become apparent especially when its description focuses on a truly theological understanding of knowledge of God: Augustine aims at leading the reader to the vision and enjoyment of God the Trinity, in whose image we are created. This mystagogical aspect of the rhetoric of De Trinitate is unfolded through Christology, soteriology, doctrine of the Holy Spirit and doctrine of revelation. At the same time, from the vantage point of love, Augustine detects and powerfully depicts the epistemological consequences of human sinfulness, thus unmasking the fundamental deficiency of received theories of knowledge. Only love restores knowledge and enables philosophers to yield to the injunction which resumes philosophical enterprise as a whole, namely 'know thyself'.
