At the turn of the sixth century the Mediterranean world was witnessing the decline of Roman rule that had formed the bedrock of its civil order. During the chaos of those years, there arose in the deserts of Egypt and Syria monastic movements that offered men and women a radical God-centered alternative to the present society. Among the most eloquent interpreters of the new movement to western Europe was John Cassian (c. 365-c. 435). Drawing on his own early experience as a monk in Bethlehem and Egypt, he journeyed to the West to found monasteries in Marseilles and the region of Provence.
