The essays in this volume situate the Nag Hammadi Codices and their texts in the context of late antique Egypt, treating such topics as Coptic readers and readings, the difficulty of dating early Greek and Coptic manuscripts, scribal practices, the importance of heavenly ascent, asceticism, and instruction in Egyptian monastic culture. They also explore the relationship of the texts to the Origenist controversy and Manichaeism, the continuity of mythical traditions in later Coptic literature, and issues relating to the codices' production and burial. The volume thus showcases the new trend in scholarship to treat the Nag Hammadi Codices not as sources for Gnosticism, but instead for Christianity and monasticism in late antique Egypt.
