Theodore Freylinghuysen Collier, 1911 Encyclopædia Britannica, Volume 6… (1911)
“ Sardinia and Sicily, Parma and Piacenza, were disposed of without regard to papal claims. When he quarrelled with the duke of Savoy, and revoked his investiture rights in Sicily (1715) , his interdict was treated with contempt. The prestige of the papacy had hardly been lower within two centuries. About 1702 the Jansenist controversy broke out afresh. Clement reaffirmed the infallibility of the pope, in matters of fact (1705) , and, in 1713, issued the bull Unigenitus, condemning 101 Jansenistic propositions extracted from the Moral Reflections of Pasquier Quesnel. ”
