Platonic Theories of Prayer is a collection of ten essays on the topic of prayer in the later Platonic tradition. The volume originates from a panel on the topic held at the 2013 ISNS meeting in Cardiff, but is supplemented by a number of invited papers. Together they offer a comprehensive view of the various roles and levels of prayer characteristic of this period. The concept of prayer is shown to include not just formal petitionary or encomiastic prayer, but also theurgical practices and various states of meditation and ecstasy practised by such major figures as Plotinus, Porphyry, Iamblichus, Proclus, Damascius or Dionysius the Areopagite.

Prayer and Worship in Eastern Christianities, 5th to 11th Centuries forges a new conversation about the diversity of Christianities in the medieval eastern Mediterranean, centered on the history of practice, looking at liturgy, performance, prayer, poetry, and the material culture of worship. It studies prayer and worship in the variety of Christian communities that thrived from late antiquity to the middle ages: Byzantine Orthodoxy, Syrian Orthodoxy, and the Church of the East. Rather than focusing on doctrinal differences and analyzing divergent patterns of thought, the essays address common patterns of worship, individual and collective prayer, hymnography and liturgy, as well as the indigenous theories that undergirded Christian practices. The volume intervenes in standard academic discourses about Christian difference with an exploration of common patterns of celebration, commemoration, and self-discipline. Essays by both established and promising, younger scholars interrogate elements of continuity and change over time – before and after the rise of Islam, both under the control of the Eastern Roman Empire and in the lands of successive caliphates. Groups distinct in their allegiances nevertheless shared a common religious heritage and recognized each other – even in their differences – as kinds of Christianity. A series of chapters explore the theory and practice of prayer from Greco-Roman late antiquity to the Syriac middle ages, highlighting the transmission of monastic discourses about prayer, especially among Syrian and Palestinian ascetic teachers. Another set of essays examines localization of prayer within churches through inscriptions, donations, dedications, and incubation. Other chapters treat the composition and transmission of hymns to adorn the liturgy and articulate the emotions of the Christian calendar, structuring liturgical and eschatological time.

Gregory of Nyssa’s Homilies on the Our Father, edited by Matthieu Cassin, Hélène Grelier-Deneux and Françoise Vinel, offers an English translation, the edition of a 15th century Latin translation and twenty-seven studies on this major text of the 4th century.

Providing a metaphysical grounding for liturgical participation, this book argues that “active participation” in the liturgy must be understood principally as our participation in God’s act, particularly in the act of Christ, and only secondarily as our ritual involvement. Utilizing Neoplatonist philosophy, Kjetil Kringlebotten proposes that this should be understood in terms of theurgy, which is the human participation in divine action, which finds its consummation in the incarnation of Christ. Without the incarnation all acts will remain extrinsic and imposed but acts can become real and intrinsic precisely because the incarnation makes possible true union with the divine, a metaphysical union-in-distinction, without confusion, because this union is not extrinsic. Through union with Christ, as the one common focus of the divine-human relation, we can have true union with God and may offer true worship. In order to make sense of active participation, then, we need to understand theology in theurgic terms, where theurgy is understood not as a mechanical “coercion” of God but as a participation in His act, in creation and through Christ as the true theurgist, the “master theurgist,” Whose work transforms our act and the liturgy.

Brill’s Companion to the Reception of Plato in Antiquity offers a comprehensive account of the ways in which ancient readers responded to Plato, as philosopher, as author, and more generally as a central figure in the intellectual heritage of Classical Greece, from his death in the fourth century BCE until the Platonist and Aristotelian commentators in the sixth century CE. The volume is divided into three sections: ‘Early Developments in Reception’ (four chapters); ‘Early Imperial Reception’ (nine chapters); and ‘Early Christianity and Late Antique Platonism’ (eighteen chapters). Sectional introductions cover matters of importance that could not easily be covered in dedicated chapters. The book demonstrates the great variety of approaches to and interpretations of Plato among even his most dedicated ancient readers, offering some salutary lessons for his modern readers too.

This volume examines the discussion of the Chaldean Oracles in the work of Proclus, as well as offering a translation and commentary of Proclus’ Treatise On Chaldean Philosophy. Spanu assesses whether Proclus’ exegesis of the Chaldean Oracles can be used by modern research to better clarify the content of Chaldean doctrine or must instead be abandoned because it represents a substantial misinterpretation of originary Chaldean teachings. The volume is augmented by Proclus’ Greek text, with English translation and commentary. Proclus and the Chaldean Oracles will be of interest to researchers working on Neoplatonism, Proclus and theurgy in the ancient world.

The book is a critical edition of the text with an English translation and commentary of Proclus’ On the Hieratic Art according to the Greeks. The Hieratic Art is the Theurgic Art, theurgy, the theurgic union with the divine. Proclus describes the theurgic union, putting an emphasis on a conceptual blending of ritual actions (teletai, e.g. the role of statues, incenses, synthêmata, symbols, purifications, invocations and epiphanies) and philosophical concepts (e.g. union of many powers, ‘one and many’, symphathy, natural sympathies, attraction, mixing and division).
