twenty-four days later, du Perron participated in the election of Cardinal Camillo Borghese as Paul V. At the conclusion of the Coronation festivities, Cardinal du Perron wrote a report of the Conclave for Henry IV. After his election, Paul V decided to continue the Congregation de auxiliis, and therefore du Perron was one of the Judges who began meeting again on 14 September 1605. He complained in a letter to Henry IV that he was constrained to read everything that had been published on the question during the previous eight or nine years. Although he appeared to work well with the Jesuit Cardinal Robert Bellarmine, in presenting the positions of Molinism fairly, du Perron's repeated counsel was not to take any decisions on the basic issues of the matter. Du Perron, after all, had strong Augustinian tendencies, which tended to make Molina's positions uncongenial. Even when he had returned to France in 1607, the Jesuits kept attempting to draw him into their circle, but without success. But, while du Perron was still in Rome, Pope Paul V decided to pick a quarrel with the Republic of Venice, over its conduct in exercising its sovereign rights. The Venetian government had passed a law against alienation of property in favor of the Church, and another requiring governmental approval for the building of new churches. In addition, there was the very old argument over the exemption of the clergy from civil court jurisdiction. On 17 April 1606 Pope Paul launched a bull against Venice, imposing an interdict on all the territories belonging to the Serenissima. This was certain to lead to war, and would very likely excite the greed of Spain for additional territory in Lombardy. Henry IV, wishing to prevent this, proposed mediation between the Pope and Venice, and offered Cardinal de Joyeuse and Cardinal du Perron as mediators. The status of the Jesuits, who supported the papal interdict, became the main sticking point; the Venetians wanted them gone. Finally, due to the forceful persuasion of Cardinal de Joyeuse (du Perron claimed to be ill), the Pope gave way, the edict was withdrawn, and the crisis averted. Nonetheless, for the work that he had done, the Republic offered du Perron its thanks. In 1606, while still in Rome, du Perron was appointed archbishop of Sens by the King, an act approved by Pope Paul V in Consistory on 9 October 1606. Like
