This volume is both an essay in Gnostic poetics and a study in the history of early Christian appropriation of ancient philosophy. The object of study is the cosmological model of the Apocryphon of John, a first-hand and fully narrated version of the Gnostic myth.The author examines his target text against a complex background of religious and philosophical systems, literary theories, and rhetorical techniques of the period, and argues that the world model of the Apocryphon of John is inseparable from the epistemological, theological, and aesthetic debates within contemporary Platonism. Poetics of the Gnostic Universe also discusses the composition and narrative logic of the Apocryphon of John, explores its revisionist attitude towards various literary models (Plato's Timaeus, Wisdom literature, Genesis), and analyzes its peculiar discursive strategy of conjoining seemingly disconnected symbolic 'codes' while describing the derivation of a multi-layered universe from a single transcendent source.
