In the year 529 a.d., St. Benedict, an Italian of noble birth and great reputation, introduced into his new monastery on Monte Cassino—a hill between Rome and Naples—a new monastic rule. To the three vows of obedience, poverty, and chastity, which formed the foundation of most of the old rules, he added another, that of manual labour (for seven hours a day), not only for self-support, but also as a duty to God and man.
