This book is the first publication of a very early collection of Christian monastic rules from Roman Egypt. Designed for the so-called White Monastery Federation, a community of monks and nuns who banded together about 360 CE, the rules are quoted by the great monastic leader Shenoute of Atripe in his writings of the fourth and fifth century. These rules provide new and intimate access to the earliest phases of Christian communal (cenobitic) monasticism.
