chapter 3 Between the Prince and the Pope: Pius v and the Rise of the Roman Inquisition When cardinal- inquisitor Michele Ghislieri became Pope Pius v in January 1566 senior Jesuits predicted that, as pope, he would prioritise the work of the Roman Inquisition. Just days after the conclave closed, Superior General Francesco Bor- ja wrote that ‘matters of Reform and the Inquisition [would] come first’ under a Ghislieri pope.1 Others in Rome agreed. In a letter of March 1566, the Venetian ambassador to the Holy See claimed that ‘matters of religion would be the most favoured’ by Pius, ‘and particularly of the Inquisition’.2 Another Italian writer told the Archbishop of Santa Severina, Giulio Antonio Santoro, that Pius v’s pontifi- cate would herald a return to the inquisitorial severity of his mentor, Pope Paul iv (1555– 9). ‘To Rome, to Rome, what awaits you?’ he asked, ‘come happily, God has revived Paul iv there’.3 Pius v soon corroborated these predictions. As pope, he established the Roman Inquisition as a stable institution, building permanent headquarters for the congregation at a cost of more than 50,000 scudi.4 In 1568, he publicly executed Paul iv’s enemy Pietro Carnesecchi, the Florentine nobleman who had escaped condemnation for heresy at Paul’s death in 1559.5 In 1570, Pius established the Congregation of the Index, re- imposing Paul iv’s rigorous cen- sorship of heretical books and reversing the more moderate guidelines set by 1 arsi, Epistolae Generalium Italiae 66, f.122r. 2 Paolo Tiepolo in Fabio Mutinelli, Storia arcana e aneddotica d’Italia, raccontata dai veneti ambasciatori (Venice: Pietro Naratovich, 1855– 6), vol. 1, p.38. 3 Marcantonio Fiorenzo to Giulio Antonio Santoro, 9 January 1566, published in G.

A witness at the trial of Count Niccolò Orsini claimed that ‘at the time of Pope Paul [iv] … [Orsini] never went to mass’.8 It seemed that the count was not so afraid of Carafa. Under Pius v, however, it was said that Orsini was terrified about the potential consequences of his past transgressions.9 If Pius v was to take a similar or even harsher approach to that of Paul iv it was very bad news for the Society’s privilege to absolve heresy. Paul iv had tried to negate the Jesuits’ privilege, issuing a brief that required all confessors, including Jesuits, to refuse absolutions until penitent-heretics had visited the Holy Office, though the Jesuits do not appear to have been held to this.10 Doc- uments produced to defend the privilege in the 1580s suggest that Pius v fol- lowed the example of his mentor. The papers list concessions of the privilege from Julius iii’s pontificate onwards. Some fall silent after the concession of Pius v’s predecessor, Pius iv, before moving on to the concessions of his suc- cessor, Gregory xiii, suggesting that Pius failed to re- concede the power.11 An- other list notes that Pius v did concede the privilege, before stating that Greg- ory xiii granted the same but ‘also in Italy’.12 This wording implies that Pius v only confirmed the privilege for northern Europe and that Gregory extended it to Italy to restore the power to the same level as the Jesuits had previously 6 Romeo, L’Inquisizione nell’Italia moderna, p.19.
