The position of the Holy Office in Venice was so far peculiar as to justify a digression upon its special constitution. Always jealous of ecclesiastical interference, the Republic insisted on the Inquisition being made dependent on the State. Three nobles of senatorial rank were chosen to act as Assessors of the Holy Office in the capital; and in the subject cities this function was assigned to the Rectors, or lieutenants of S. Mark. It was the duty of these lay members to see that justice was impartially dealt by the ecclesiastical tribunal, to defend the State against clerical encroachments, and to refer dubious cases to the Doge in Council. They were forbidden to swear oaths of allegiance or of secrecy to the Holy Office, and were bound to be present at all trials, even in the case of ecclesiastical offenders. No causes could be avvocated to Rome, and no crimes except heresy were held to lie within the jurisdiction of the court. The State reserved to itself witchcraft, profane swearing, bigamy and usury; allowed no interference with Jews, infidels and Greeks; forbade the confiscation of goods in which the heirs of condemned persons had interest; and made separate stipulations with regard to the Index of Prohibited Books. It precluded the Inquisition from extending its authority in any way, direct or indirect, over trades, arts, guilds, magistrates, and communal officials.[106] The tenor of this system was to repress ecclesiastical encroachments on the State prerogatives, and to secure equity in the proceedings of the Holy Office. Had practice answered to theory in the Venetian Inquisition, by far the worst abuses of the institution would have been avoided. But as a matter of fact, causes were not unfrequently transferred to Rome; confiscations were permitted; and the lists of the condemned include Mussulmans, witches, conjurors, men of scandalous life, etc., showing that the jurisdiction of the Holy Office extended beyond heresy in Venice.[107]
