REVIEWSAmong the sources for the history of Byzantine monasticism, none are more important than the typika, or foundation documents. Collected and translated in these volumes, the typkia may be used, for the first time, as a comprehensive study of religious life and institutions in the Greek East and as a comparison between Greek and Latin monasticism. Together, the typika illuminate almost every aspect of Byzantine monastic life and its development from the eighth to the fifteenth century.
