“ The night of his marriage he secretly left his father's house and journeyed to Edessa in the Syrian Orient where, for seventeen years, he led the life of a pious ascetic. As the fame of his sanctity grew, he left Edessa and returned to Rome, where, for seventeen years, he dwelt as a beggar under the stairs of his father's palace, unknown to his father or wife. ”
