Surname of LEO MARSICANUS, Benedictine chronicler, b. about 1045; d. 22 May, 1115, 1116, or 1117. He belonged to an old noble family, and at the age of fourteen entered Monte Cassino, where his talents soon won him the regard of Abbot Desiderius, later Pope Victor III. Desiderius entrusted his education to the future Cardinal Aldemar. On the completion of his studies, Ostiensis became librarian and archivist of the monastery, and, as such, his main task was to settle, in accordance with the existing documents, all disputes concerning landed property in which the monastery became involved. Abbot Oderisius, who succeeded Desiderius, urged Ostiensis to write a history of the monastery, but, on account of his numerous duties, he was unable to give himself entirely to the work. Paschal II created him Cardinal Bishop of Ostia. In the conflict between the pope and Henry V, Ostiensis vigorously defended the papacy. His unfinished chronicle, originally called "Legenda sancti Benedicti longa", treats the period between 529 and 1075; Petrus Diaconus continued it to 1139. Trustworthy and impartial, the chronicle is a valuable mine of information for the history of Lower Italy, but as the documents on which the narrative rests are still extant, it has no special importance for our knowledge of the time. It was first edited under the title, "Chronica sacri monasterii Casinensis auctore Leone cardinal episcopo Ostiensi", by Abbot Angelus de Nuce (Paris, 1668); then by Wattenbach in "Monumenta Germaniae: Scriptores", VII, 574-727, and Migne in "P.L.", CLXXIII, 479-763. Ostiensis has left several lesser works: "Narratio de consecratione ecclesiarum a Desiderio et Oderisio in Monte Casino aedificatarum" (P.L., CLXXIII, 997-1002), and "Vita sancti Mennatis eremitae et confessoris" (edited in part, P.L., CLXXIII, 989-92).

The Catholic Encyclopedia is the most comprehensive resource on Catholic teaching, history, and information ever gathered in all of human history. This easy-to-search online version was originally printed in fifteen hardcopy volumes.
Designed to present its readers with the full body of Catholic teaching, the Encyclopedia contains not only precise statements of what the Church has defined, but also an impartial record of different views of acknowledged authority on all disputed questions, national, political or factional. In the determination of the truth the most recent and acknowledged scientific methods are employed, and the results of the latest research in theology, philosophy, history, apologetics, archaeology, and other sciences are given careful consideration.
No one who is interested in human history, past and present, can ignore the Catholic Church, either as an institution which has been the central figure in the civilized world for nearly two thousand years, decisively affecting its destinies, religious, literary, scientific, social and political, or as an existing power whose influence and activity extend to every part of the globe. In the past century the Church has grown both extensively and intensively among English-speaking peoples. Their living interests demand that they should have the means of informing themselves about this vast institution, which, whether they are Catholics or not, affects their fortunes and their destiny.
