Besides this, he wished to build the Papal Palace with so much magnificence and grandeur, and with so many conveniences and such loveliness, that it might be in all respects the greatest and most beautiful edifice in Christendom; and he intended that it should not only serve for the person of the Supreme Pontiff, the Chief of all Christians, and for the sacred college of Cardinals, who, being his counsellors and assistants, had always to be about him, but also that it should provide accommodation for the transaction of all the business, resolutions, and judicial affairs of the Court; so that the grouping together of all the offices and courts would have produced great magnificence, and, if such a word may be used in such a context, an effect of incredible pomp. What is infinitely more, it was meant for the reception of all Emperors, Kings, Dukes, and other Christian Princes who might, either on affairs of their own or out of devotion, visit that most holy apostolic seat. It is incredible, but he proposed to make there a theatre for the crowning of the Pontiffs, with gardens, loggie, aqueducts, fountains, chapels, libraries, and a most beautiful building set apart for the Conclave. In short, this edifice--I know not whether I should call it palace, or castle, or city--would have been the most superb work that had ever been made, so far as is known, from the Creation of the world to our own day. What great glory it would have been for the Holy Roman Church to see the Supreme Pontiff, her Chief, gather together, as into the most famous and most holy of monasteries, all those ministers of God who dwell in the city of Rome, to live there, as it were in a new earthly Paradise, a celestial, angelic, and most holy life, giving an example to all Christendom, and awakening the minds of the infidels to the true worship of God and of the Blessed Jesus Christ! But this great work remained unfinished--nay, scarcely begun--by reason of the death of that Pontiff; and the little that was carried out is known by his arms, or the device that he used as his arms, namely, two keys crossed on a field of red. The fifth of the five works that the same Pope intended to execute was the Church of S. Pietro, which he had proposed to make so vast, so rich, and so ornate, that it is better to be silent than to attempt to speak of it, because I could not describe even the least part of it, and the rather as the model was afterwards destroyed, and others have been made by other architects. If any man wishes to gain a full knowledge of the grand conception of Pope Nicholas V in this matter, let him read what Giannozzo Manetti, a noble and learned citizen of Florence, has written with the most minute detail in the Life of the said Pontiff, who availed himself in all the aforesaid designs, as has been said, as well as in his others, of the intelligence and great industry of Bernardo Rossellino.
