The monastic life, as a system, was not much known till the end of the fourth century. It has been conjectured that the circumstances of the Decian persecution, about the middle of the third century, caused many persons in Egypt to retreat for safety to the desert, and then, finding complete security, this became a second nature, the climate being mild and cells and cottages being easily constructed. There were at first only individuals here and there, and no regular society till the peaceable reign of Constantine, when Pachomius is said to have founded some monasteries in Thebais. Antony, the first hermit of note, gave a contemporary of Pachomius this account: "When I first became a monk, there was as yet no monastery in any part of the world where one man was obliged to take care of another, but every one of the ancient monks, when the persecution was ended, exercised the monastic life by himself in private. Afterwards Father Pachomius, by the help of God, brought the monks to live in communities." Before 250 those who lived a lonely life were called ascetics. Hilarion, who was scholar to Antony, was the first monk who ever lived in Palestine or Syria. Not long after this new mode of life spread to Armenia, Paphlagonia, and Pontus; then it reached Thrace and parts of Europe. It was not till Athanasius came to Italy and Rome in 340 that he introduced this mode of society. Marcella was the first noble woman who took to this life at Rome, being instructed by Athanasius during the Arian persecution. Pelagius, about 400, introduced monastic life into Britain. Monks at first were laymen and not clergy, their office being not to teach but to mourn. It was not till after 1311 that Pope Clement obliged all monks to take holy orders, so that they might say private Mass for the honour of God. THE TEMPTATIONS OF ST. ANTONY (A.D. 340).
