St. Benedict of Nursia retired to Subiaco c.497 and lived there with his disciples until 529, when he moved to Monte Casino. The Benedictine abbey, which grew out of the 12 monastic communities founded there by the saint, rose to great wealth and political power in the Middle Ages. St. Scholastica, St. Benedict's sister, established in Subiaco the first monastic community for women. In 1464 the first printing press in Italy was established in Subiaco.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
