William of Vercelli, St.


Abbot; b. Vercelli, Piedmont, 1085; d. monastery of S. Salvatore at Goleto (or, Guglieto), near Nusco, Italy, June 25, 1142. He was the founder of the now extinct congregation of Benedictine monks called williamites (1119) and of the celebrated abbey and shrine of Our Lady of Monte Vergine, near Avellino, southern Italy. At 14 he gave up his inheritance and made a pilgrimage to Santiago de Compostela, Spain. Upon returning to Italy in 1106, he began to live as a hermit. Some time later he built a cell on a mountain in the Partenio range, which he renamed Monte Vergine, and here he built the shrine to Our Lady, 1124. His first companions joined him in 1118 and 1119. When disagreements arose over alms received, William with five others moved to another mountain called Serra Cognata. Subsequently, he founded other monasteries, including the double monastery (see monastery, double) near Nusco, in southern Italy where he died at the age of 57. A Latin life of William by Felix Renda was published in Naples (1581), and another by Joannes Jacobus also at Naples (1643). His cultus was confirmed in 1728 and 1785.

Feast: June 25; Sept. 2 (translation).

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:
