monks lived in individual huts or rooms (cellula in Latin,) but worked, ate, and worshipped in shared space. The intention was to bring together individual ascetics who, although pious, did not, like Saint Anthony, have the physical ability or skills to live a solitary existence in the desert. This method of monastic organization is called cenobitic or "communal". In Catholic theology, this community-based living is considered superior because of the obedience practiced and the accountability offered. The head of a monastery came to be known by the word for "Father"—in Syriac, Abba; in English, "Abbot". Guidelines for daily life were created, and separate monasteries were created for men and women. St Pachomius introduced a monastic Rule of cenobitic life, giving everyone the same food and attire. The monks of the monastery fulfilled the obediences assigned them for the common good of the monastery. Among the various obediences was copying books. St Pachomius considered that an obedience fulfilled with zeal was greater than fasting or prayer. A Pachomian monastery was a collection of buildings surrounded by a wall. The monks were distributed in houses, each house containing about forty monks. There would be thirty to forty houses in a monastery. There was an abbot over each monastery and provosts with subordinate officials over each house. The monks were divided into houses according to the work they were employed in: thus there would be a house for carpenters, a house for agriculturists, and so forth. But other principles of division seem to have been employed, e.g., there was a house for the Greeks. On Saturdays and Sundays, all the monks assembled in the church for Mass; on other days the Office and other spiritual exercises were celebrated in the houses. From a secular point of view, a monastery was an industrial community in which almost every kind of trade was practised. This, of course, involved much buying and selling, so the monks had ships of their own on the Nile, which conveyed their agricultural produce and manufactured goods to the market and brought back what the monasteries required. From the spiritual point of view, the Pachomian monk was a religious living under a rule. The community of Pachomius was so successful he was called upon to help organize others, and by one count by the time he died in 346 there were thought to be 3,000 such communities dotting Egypt, especially in
