"Bernin s'ingéra de creuser un des fameux piliers de St. Pierre pour y pratiquer un petit escalier montant à la tribune; aussitôt le dôme prit coup et se fendit. On fut obligé de le relier tout entier avec un cercle de fer. Ce n'est point raillerie, le cercle y est encore; le mal n'a pas augmenté depuis. Par malheur pour le pauvre cavalier, on trouva dans les Mémoires de Michel-Ange qu'il avait recommandé, sub pœnâ capitis, de ne jamais toucher aux quatre piliers massifs faits pour supporter le dôme, sachant de quelle masse épouvantable il allait les charger; le pape voulait faire pendre Bernin, qui, pour se rédimer, inventa la fontaine Navone."—De Brosses.

The lower fountain, also by Bernini, is adorned with tritons and the figure of a Moor. The great palace to the right of the church is the Palazzo Pamfili, built by Rainaldi for Innocent X. in 1650. It possesses a ceiling painted by Pietro di Cortona with the adventures of Eneas. Its music-hall is still occasionally used for public concerts.

It was in this palace that the notorious Olympia Maldacchini, foundress of the Pamfili fortunes, besported herself during the reign of her brother-in-law, Innocent X.

"The great object of Donna Olympia was to keep at a distance from Innocent every person and every influence that could either lessen her own, or go shares in the profits to be extracted from it. For this, after all, was the great and ultimate scope of her exertions. To secure the profits of the papacy in hard cash; this was the problem. No appointment to office of any kind was made, except in consideration of a proportionable sum paid down into her own coffers. This often amounted to three or four years' revenue of the place to be granted. Bishoprics and benefices were sold as fast as they became vacant. One story is told of an unlucky disciple of Simon, who on treating with the popess, for a very valuable see, just fallen vacant, and hearing from her a price, at which it might be his, far exceeding all he could command, persuaded the members of his family to sell all they had for the purpose of making this profitable investment. The price was paid, and the bishopric was given to him, but with a fearful resemblance to the case of Ananias, he died within the year; and his ruined family saw the see a second time sold by the insatiable and incorrigible Olympia.... During the last year of Innocent's life, Olympia literally hardly ever quitted him. Once a week, we read, she left the Vatican, secretly by night, accompanied by several porters carrying sacks of coin, the proceeds of the week's extortions and sales, to her own palace. And, during these short absences, she used to lock the pope into his chamber, and take the key with her!"—Trollope's Life of Olympia Pamfili.

On the opposite side of the piazza, some architectural fragments denote the half-ruined Church of S. Giacomo degli Spagnuoli of the fifteenth century. It possesses a gothic rose window, which is almost unique in Rome. There is a handsome door on the other side towards the Via della Sediola. The lower end of the square near this is occupied by the Palazzo Lancellotti, built by Pirro Ligorio, behind which is the frescoed front of Palazzo Massimo, mentioned above. The Piazza Navona has been used as a market ever since 1447. In the hot months, the singular custom prevails of occasionally stopping the escape of water from the fountains, and so turning the square into a lake, through which the rich splash about in carriages, and eat ices and drink coffee in the water, while the poor look on from raised galleries. It is supposed that this practice is a remnant of the pleasures of the Naumachia, once annually exhibited almost on this very spot, formerly the Circus Agonalis.

Vitale Mascardi gives an extraordinary account of the magnificent tournament held here in 1634 in honour of the visit of Prince Alexander of Poland, when the piazza was hung with draperies of gold and silver, and Donna Anna Colonna and Donna Costanza Barberini awarded gorgeous prizes of diamonds to noble and princely competitors.

Nearly opposite Sant' Agnese, a short street leads (passing on the left, Arvotti's, the famous Roman-scarf shop) to the front of the Palazzo Madama, which is sometimes said to derive its name from Margaret of Parma, daughter of Charles V., who once occupied it, and sometimes from Catherine de' Medici, who also lived here, and under whom it was altered in its present form by Paolo Marucelli. The balcony towards the piazza is the scene every Saturday at noon of the drawing of the Roman lottery.

"In the middle of the balcony, on the rail, is fixed a glass barrel, with a handle to turn it round. Behind it stand three or four officials, who have been just now ushered in with a blast from two trumpeters, also stationed in the balcony. Immediately behind the glass barrel itself stands a boy of some twelve or thirteen years, dressed in the white uniform of one of the orphan establishments, with a huge white shovel hat. Some time is occupied by the folding, and putting into the barrel, pieces of paper, inscribed with the numbers, from one onwards. Each of these is proclaimed, as folded and put in, by one of the officials who acts as spokesman or crier. At last, after eighty-seven, eighty-eight, and eighty-nine have been given out, he raises his voice to a chant, and sings forth, Numero novanta, 'number ninety,' this completing the number put in.

"And now, or before this, appears on the balcony another character—no less a person than a Monsignore, who appears, not in his ordinary, but in his more solemn official costume; and this connects the ceremonial directly with the spiritual authority of the realm. And now commences the drawing. The barrel having been for some time turned rapidly round to shuffle the numbers, the orphan takes off his hat, makes the sign of the cross, and having waved his open hand in the air to show that it is empty, inserts it into the barrel, and draws out a number, giving it to the Monsignore, who opens it and hands it to the crier. This latter then proclaims it—'Prima-estratta, numero venti cinque.' Then the trumpets blow their blast, and the same is repeated four times more: the proclamation varying each time, Seconda estratta, Terza, Quatra, Quinta, etc., five numbers being thus the whole drawn, out of ninety put in. This done, with various expressions of surprise, delight, or disappointment from the crowd below, the officials disappear, the square empties itself, and all is as usual till the next Saturday at the same time....

"In almost every street in Rome are shops devoted to the purchase of lottery tickets. Two numbers purchased with the double chance of these two numbers turning up are called an ambo, and three purchased with the treble chance of those three turning up, are called a terno, and, of course, the higher and more perilous the stake, the richer the prize, if obtained."—Alford's Letters from Abroad.
