Those seem to follow the model of Saint Pachomius. But, what about the more eremitical forms? From reading the Desert Fathers, it seems that another common model (besides the cenobitic form introduced by Saint Pachomius) was you walk out into the desert and find some form of shelter. There you do some menial work -- like weave baskets or rope -- the fruits of which would be taken by the lay faithful and sold and the proceeds would go to buy the hermit things they needed, such as bread and more raw materials for work. Every once in a great while, a bunch of hermits would meet for Liturgy, or to try another brother, or to their spiritual father for instruction.
Is that model of monastic life still alive?
