Spanish Inquisition were enforced, while for the similar orders of the Inquisition of Rome or of the Congregation of the Index, the enforcement throughout the States of Italy or outside of Italy was but vacillating and fragmentary. An example of the watchfulness of the Spanish examiners is given in the expurgation of a passage from the Second Part of _Don Quixote_. But a single sentence is cancelled. It reads: “Works of charity negligently performed are of no worth.” In the _Divine Comedy_ of Dante, the censors found but three passages for excision. Lea points out that for this work at least the examination can hardly be described as thorough.[117] In 1790, the history of the monastery of Sixena, by Varon, which had been published with the approval of the royal examiners in 1776, was prohibited until the following sentence had been expurgated: “When Philip the Second was despoiling the world to enrich his monastery of the Escorial.” The Inquisition of Spain even assumed for itself the authority to revise and correct the utterances of the popes. The State utilised the censorship of the Inquisition not only for matters theological but for the suppression of writings that were purely political. Instructions of Clement VIII were accepted as the authority for the expurgation of teachings that were derogatory to princes and to ecclesiastics and contrary to good morals. In 1612, for instance, the works of Antonio Perez were placed on the Index because they were critical of Philip II.[118] In 1640, the Inquisition suppressed a manifesto addressed by the authorities of Barcelona to Philip IV, and, in 1642, it prohibited a further manifesto in which the Catalans accused the favourite, Olivares, of causing the misfortunes of Spain. In 1643, on the other hand, after the dismissal of Olivares, the Inquisition prohibited a pamphlet which had been issued in his defence. [Sidenote: Book-trade and the Inquisition]
