Benedict was influenced by the Early Christian monastic movement and the pursuit of God.
In the second volume of Dialogues, Pope Gregory the Great (590-604), who encouraged Benedictine monasticism, wrote a legendary biography about Benedict, the patriarch of the Benedictine monks. It is written that Benedict ended his studies in Rome because he felt the need to serve only God. For several years, he lived in solitude in a cave in Subiaco, located in Aniene Valley near Rome. Numerous disciples joined him there, founding a number of small monastic communities. In 529, Benedict relocated with some of his monks to Monte Cassino, a hill above the city of Cassino set between Rome and Naples (in modern-day Lazio) and established a monastery at the site of a pre-Christian sanctuary.
It was for the growing monastic community here that he wrote the most significant document in Western monasticism, the Rule of St. Benedict, or “regula Benedicti.” Benedict died at Monte Cassino on March 21, 547.
