The Desert Fathers advocated three main approaches to monasticism. One was the austere life of the hermit, as practiced by Anthony and his followers in lower Egypt. Another was the cenobitic life, communities of monks and nuns in upper Egypt formed by Pachomius. The third was a semi-hermitic lifestyle seen mostly in Nitria, Kellia and Scetis, west of the Nile, begun by Saint Amun. The latter were small groups (two to six) of monks and nuns with a common spiritual elder—these separate groups would join together in larger gatherings to worship on Saturdays and Sundays. This third form of monasticism was responsible for most of the sayings that were compiled as the "Apophthegmata Patrum" ("Sayings of the Desert Fathers").
