The present volume is focused on the interactions and syncretistic tensions between religion and philosophy in Late Antiquity. A variety of papers examine issues of personal religious attitudes, initiation to the mysteries, Orphism, notions of theurgy, magic, the philosopher’s quest for intimacy or union with the divine, magic and Christianity, the role of prayer in philosophical texts, and oracles, dream-visions and divination. The contributions include a wide range of specialisations, such as Neoplatonism, Chaldaean Oracles, Theurgy, Patristic literature, Christian religious texts and Manichaeism.
