Peter Monoculus, Bl.


Abbot of clairvaux; b. Burgundy, France; d. Foigny, France, Oct. 29, 1186. Peter, the son of a noble family, joined the Cistercian community in his early youth. In 1164 he was elected abbot of Valroy, where in a nearly fatal illness he lost an eye. He became abbot at Igny (1169), then at Clairvaux (1179). A worthy successor of St. bernard in his humility and love of poverty, he was held in the highest esteem by the popes and monarchs of his time. He died while on a tour of visitation at Foigny, but was buried at Clairvaux. Sixteen of Peter's letters have been edited (Patrologia Latina 201:13911404). Although never officially canonized, his cult is widespread among Cistercians.

Feast: Oct. 29.

Learn more about citation styles

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:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
