Ascetical Life
By tradition Peter began his ascetic course as a child, leaving home at the age of seven, and lived for many years as a wandering monk. The sources describe a progression of places: he first remained in Galatia, then went to Palestine, and finally came to Antioch in Syria, where he settled permanently.
At Antioch he took up residence in an abandoned tomb, which became the setting of his strict enclosure. There he practiced an austere regimen of prayer and fasting, eating bread and water only on alternate days. This pattern of life — solitude, extreme simplicity of food, and continual prayer — placed him among the noted ascetics of the Syrian region described in the same period.
