Annales Ecclesiastici (full title Annales ecclesiastici a Christo nato ad annum 1198 - ecclesiastical annals from the nativity to 1198), consisting of twelve folio volumes, is a history of the first 12 centuries of the Christian Church, and was authored by Cardinal Caesar Baronius. It was first published between 1588 and 1607 as a response to the Lutheran Historia Ecclesiae Christi (History of the Church of Christ) in which the Magdeburg theologians surveyed the history of the church in order to demonstrate how the Catholic Church represented the antichrist and had deviated from the beliefs and practices of the early church.
Significance
Because Baronius was the Vatican librarian, he had access to the use of this material and sources in the archives previously unpublished or omitted. He used these in the development of his work. Accordingly, Annales Ecclesiastici is considered by most as extremely useful and complete. Early Protestant scholars accused it of being "by no means critical; it is intensely Roman Catholic".
