Benedict of Nursia (; ; Vulgar Latin: *Benedecto; ; 2 March 480 – 543 or 547 AD) is a Christian saint, who is venerated in the Eastern Orthodox Churches, the Catholic Church, the Oriental Orthodox Churches, the Anglican Communion and Old Catholic Churches. He is a patron saint of Europe. Benedict founded twelve communities for monks at Subiaco, Lazio, Italy (about to the east of Rome), before moving to Monte Cassino in the mountains of southern Italy. The Order of Saint Benedict is of later origin and, moreover, not an "order" as commonly understood but merely a confederation of autonomous congregations. Benedict's main achievement is his "Rule of Saint Benedict", containing precepts for his monks. It is heavily influenced by the writings of John Cassian, and shows strong affinity with the Rule of the Master. But it also has a unique spirit of balance, moderation and reasonableness (ἐπιείκεια, epieikeia), and this persuaded most religious communities founded throughout the Middle Ages to adopt it. As a result, his Rule became one of the most influential religious rules in Western Christendom. For this reason, Benedict is often called the founder of Western Christian monasticism.
