"The Gnostic Religion was the first decent introduction to Gnosticism for the modern world and is still of value today. It includes both heresiological and original texts—Nag Hammadi only uncovered later. It holds useful material on Simon Magus, the Hermetic Poimandres (shown here to be equally a Gnostic document), the Valentinians, Mandaeans, Manichaeans and the Hymn of the Pearl.
The existentialist bend—Jonas a student of Martin Heidegger—makes an interesting contrast to Pagel's more orthodox view of Gnostic religion as theistic. This volume and the Nag Hammadi library will provide good coverage of the diverse teachings of Gnostic and related movements."
