At the beginning of the Conclave the Cardinals were always divided into two, if not more parties, of such relative strength as to make the attainment of such a majority by either of them impossible for many days. It was not until the persistent intrigues of a fortnight had increased the majority of any one Cardinal so much as to give a probability of his being ultimately elected, that the waverers of all sides, not willing to be known as the opponents of a new Pope, recorded their voices in his favour, and thus raised the majority to its necessary proportion. For this very delicate matter occurred at this period of the election, that, should the requisite majority of voices be obtained, the master of the ceremonies and his brazier were no longer called for, but the whole of the papers were opened to their full extent, and the names of the voters given to the world, whereby, as one conversant in these matters observes, "Many mysteries and infidelities are brought to light." It is evident, therefore, that, as the majority of any one Cardinal increased or showed signs of increasing, morning and evening, as the suffrages were taken, the voting became a very exciting and delicate matter. No one could be certain but that at the next voting the majority from the cause mentioned would suddenly swell to the necessary size, and every man's name be made clear and plain on whose side he had been.

Upon entering the Conclave the friends of Cardinal Chigi adopted a quiet policy, and waited for the progress of events to work for them. The abuses of the late Pontificate, and the excitement and indignation of popular opinion, had made it clear to all parties that it was necessary to elect a Pope whose character and reputation would restore confidence. In these respects no one seemed more qualified than Cardinal Chigi, who was supposed to possess all the qualifications necessary to ensure the Romans from the apprehension of a revival of the past disorders, and to inspire the whole Christian world with the hopes of witnessing a worthy successor of St. Peter displaying the Christian virtues from the Papal Chair. The great reputation he had gained at Münster, the determination he was said to have manifested to reform all abuses, the authority and influence he derived from his post of Secretary of State, his attractive and gracious manner, the recommendation of the late Pope upon his death-bed,—all tended to bring his name prominently forward. He was supported by the Spanish Cardinals, chiefly on account of the enmity of the French Court and of his professed opposition to Cardinal Mazarin.

But, in spite of these advantages, the enmity of the French Court, and the opposition of the Barbarini family, the relations and supporters of the late Pope, made it necessary for his friends to observe extreme caution. The French Cardinals were ordered to vote for Sachetti, and Cardinal Barbarini for the present supported him, also, with all his party, chiefly because he had not yet made terms with the Spanish Court, which opposed Sachetti; but also, as was supposed, because he himself had aspirations towards the Papal Chair, should he find the electors favourable to such a scheme.

Upon the entrance into the Conclave, therefore, Cardinal Sachetti immediately obtained thirty-two or thirty-three votes. These were not quite so many as the Barbarini expected, and indeed had a right to count upon, after the professions which the Cardinals of the party had made. This was owing to the defection of some members of what was called the Flying Squadron, composed chiefly of young Cardinals, who were supposed to be devoted to the Barbarini, but of whom several were secretly favourable to Cardinal Chigi.

The Spanish faction, which was numerous enough to have secured the election of any Cardinal had it been united, but the members of which were agreed upon nothing but their determined opposition to Sachetti, contented itself with voting negatively at every scrutiny, making use of the form "accedo nemini." This course was pursued for two entire months, during which time the scrutinies were taken regularly morning and evening, always with a slightly varying but indecisive result.

It would be difficult to realize the wearisomeness which reigned in the Conclave during so protracted a period. The crowding together of so large a number of persons in a few apartments, the closeness of the air, and the unbroken monotony of the hours that passed so slowly, made the confinement almost intolerable. One Cardinal was taken ill, and was obliged to be removed. The great gallery was generally used by the Cardinals themselves, for exercise and conversation, while their attendants were compelled to content themselves with their masters' apartments, or the corridors and passages. Those which opened on the interior courts, and thereby afforded some fresh air, were especially resorted to. Communication from without, though in theory absolutely prevented, was really frequent, all the chief among the Cardinals receiving advices from foreign Courts, and conveying intelligence thither themselves.

At intervals the whole of the inmates were assembled to listen to Father Quaechi, preacher to the Conclave, a Jesuit, and secretly in favour of Cardinal Chigi, as was the Society in general. The sermon was so contrived as to influence its hearers considerably by its evident application to the manners and conduct of the Cardinal.

The famous De Retz, then an exile from France and a supporter of Chigi, by whom he always sat in the Chapel, was the principal intriguer in his favour. He was in communication with the nominal supporters of Barbarini, who sent him intelligence by Monsignor Fabei when to vote for Sachetti, on occasions when it would be of no real service to him, and when to refrain. On one of these latter occasions Fabei entrusted his message to Inglesant, with whom he was intimate, and it afterwards appeared that Sachetti, on that scrutiny, wanted but very few votes to have secured his election. This circumstance made a deep impression on De Retz, and he never recognized Inglesant afterwards without alluding to it.

The day after this scrutiny Cardinal Barbarini appears to have thought that the time was come for his friends to make a demonstration in his behalf, and to the astonishment of the Conclave thirty-one votes appeared in his favour in the next scrutiny. This caused the friends of Cardinal Chigi to pay more attention to his conduct, and to the discourses of his Conclavists and other partizans, who neglected no opportunity of exalting his good qualities.

The exhaustion of the Conclave became extreme. Cardinal Caraffa, who, next to Sachetti and Chigi, stood the greatest chance of election, became ill and died. Twelve other Cardinals were balloted for, one after another, without result. Cardinal San Clemente was then brought forward, and, but for the hostility of the Jesuits, might have been elected; but the Spanish Cardinals who supported him did not dare openly to offend the Society, and the election failed.
