One would suppose that the authority of the head of the Church ought to have been accepted in all cases as adequate to cover the permission required for the printing and continued circulation of a book. It appears, however, that from time to time even the papal authorisations were disregarded or failed to receive continued consideration. Dejob refers to a history of Bologna by Sigone, the publication of which was suspended, owing to the malignancy of certain Bolognese, after the approval had been secured from the examiners appointed by the pope. Baronius, the defender of the most extreme claims for the supremacy of the Papacy, secured for his monograph on Sixtus V the approbation of the papal examiner and of the master of the palace. Notwithstanding this approval, the printing of the book was blocked through some cabal and the work was held up until Cardinal Caraffa intervened to secure its publication.[102] In the year 1600, was completed, in thirteen folio volumes, the _Annales Ecclesiastici_ of Baronius, the most comprehensive work which the controversies of the Protestant revolt had as yet produced. The series was continued by various writers until, in the edition issued at Lucca in 1738–1786, it had grown to thirty-eight folio volumes, a work of which purchase was difficult and perusal impossible. A reply to Baronius was undertaken by Casaubon, who published in London in 1604 (as a fragment of the work originally planned) his _Exercitationes_, a volume of eight hundred folio pages. For the great work of Baronius, the authorities of the Church interested themselves in securing through the Church machinery channels of distribution and such reading public as was practicable considering its compass and scholastic character. The Roman idea of reforming and developing the intellectual life of the State was to follow a policy of official supervision with prohibitions and penalties. Ecclesiastical censors undertook to bring authors under a system of religious and theological obligations, and were willing to give their official approval only to works complying with their standards. Certain writers accept with docility the regulations imposed, but it is not those whose productions will live or will retain influence. The books that have not conformed to the ecclesiastical restrictions must be either reshaped or suppressed. It is not under such conditions, says Dejob, that a great literature can be produced.[103] And yet in spite of an ecclesiastical policy of restriction and repression enforced, or at least attempted, through centuries, the intellectual vitality of Italy was so great that it proved impossible to crush out its independence of thought, or even seriously to limit the expression of its spiritual and literary ideals. A scholarly Catholic of France writing in 1883 says (in substance):
