A learned and zealous Dominican, born at Piacenza about he beginning of the thirteenth century; died about 1263. It is generally said that he died in 1258 or 1259, but this in an error, as we learn from the Brief of Urban IV , by which he was called to Rome, 21 July, 1262. Little is known as to his youth and early manhood. That, however, at an early age, he was perverted by the Cathari, became on of their bishops, and remained amongst them for seventeen years, we are assured by his own humble avowal ("Summa contra Waldenses ", vi). He was led back to the Faith, most probably, by the preaching of St. Peter Martyr, joined the Order of Preachers, then recently established, and laboured zealously for many years among the heretics of Upper Italy. After the martyrdom of St. Peter he was made inquisitor for Lombardy and the Marches of Ancona. Being enraged against him, and yet unable to put him to death, the heretics finally succeeded in having him sent into exile. Thereafter we have no further mention of him except in the Brief of Urban IV. The "Summan de catharis et leonistis, sive pauperibus de Lugduno" (Paris, 1548, and by Martene in "Thes. Anecd.:, V, 1759), is the only authentic work ascribed to him. This work is a collection of the heretical doctrines of his time, and was regarded as a great authority during the Middle Ages. The edition of Gretser (Ratisbon, 1738) is much interpolated.
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 between 1907 and 1912 in fifteen hard copy 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.
