Pachomius, who died in 346, has long been regarded as the "founder of monasticism. " Available again, Philip Rousseau's careful reading of the available texts reveals that Pachomius's pioneering enterprise has been consistently misread in light of later monastic practices. Rousseau not only provides a fuller and more accurate portrait of this great teacher and spiritual director but also gives a new perspective on the development of monasticism. In a new preface Rousseau reviews the scholarly developments that have modified his views and emphases since the book was published. The result is to make Pachomius an even less assured pioneer, a man likely to have been more involved in the village and urban society of his time than previously thought.
