to practice before the Roman courts. On 8 January 1635, Chigi was named Bishop of Nardò in southern Italy and consecrated on 1 July 1635 by Miguel Juan Balaguer Camarasa, Bishop of Malta. On 13 May 1652 he was transferred to the Bishopric of Imola. Bishop Chigi was named nuncio in Cologne (1639–1651) on 11 June 1639. There, he supported Urban VIII's condemnation of the heretical book Augustinus by Cornelius Jansen, Bishop of Ypres, in the papal Bull In eminenti of 1642. Though expected to take part in the negotiations which led in 1648 to the Peace of Westphalia, Bishop Chigi (and other Catholic delegates) declined to deliberate with persons whom the Catholic Church considered heretics. Negotiations therefore took place in two cities, Osnabrück and Münster in Westphalia, with intermediaries travelling back and forth between the Protestant and the Catholic delegates. Chigi, of course, protested on behalf of the Papacy, when the treaties were finally completed, against the Treaty of Westphalia once the instruments were finally completed. Pope Innocent himself stated that the Peace "is null, void, invalid, unjust, damnable, reprobate, inane, empty of meaning and effect for all time."

On the morning of his election as he went to celebrate Mass before the final ballot, Chigi was greeted by his friend Luigi Omodei who, knowing that Chigi was soon to be elected, said: "At length that day has come, so desired by me, and so happy for the Church!" Chigi replied to Omodei by reciting Virgil and said: "That day I shall always recollect with grief; with reverence also for the gods so willed it". During the final ballot, Chigi had cast his vote for Giulio Cesare Sacchetti while in the accesso
