In passing, one may remember that Mazarin himself was born in the Region of Trevi, the son of a Sicilian,--like Crispi and Rudinì. His father was employed at first as a butler and then as a steward by the Colonna, married an illegitimate daughter of the family, and lived to see his granddaughter, Maria Mancini, married to the head of the house, and his son a cardinal and despot of France, and himself, after the death of his first wife, the honoured husband of Porzia Orsini, so that he was the only man in history who was married both to an Orsini and to a Colonna. In the light of his father's extraordinary good fortune, the success of the son, though not less great, is at least less astonishing. The magnificent Rospigliosi palace, often ascribed by a mistake to Cardinal Scipio Borghese, was the Palazzo Mazarini and Mazarin's father died there; it was inherited by the Dukes of Nevers, through another niece of the Cardinal's, and was bought from them between 1667 and 1670, by Prince Rospigliosi, brother of Pope Clement the Ninth, then reigning. Urban the Eighth, the Barberini Pope, had already left his mark on the Quirinal hill. The great Barberini palace was built by him, it is said, of stones taken from the Colosseum, whereupon a Pasquinade announced that 'the Barberini had done what the Barbarians had not.' The Barbarians did not pull down the Colosseum, it is true, but they could assuredly not have built as Urban did, and in that particular instance, without wishing to justify the vandalisms of the centuries succeeding the Renascence, it may well be asked whether the Amphitheatre is not more picturesque in its half-ruined state, as it stands, and whether the city is not richer by a great work of art in the princely dwelling which faces the street of the Four Fountains. Among the many memories of the Quirinal there is one more mysterious than the rest. The great Baths of Constantine extended over the site of the Palazzo Rospigliosi, and the ruins were in part standing at the end of the sixteenth century. It is related by a writer of those days and an eye-witness of the fact, that a vault was discovered beneath the old baths, about eighty feet long by twenty wide, closed at one end by a wall thrown up with evident haste and lack of skill, and completely filled with human bodies that fell to dust at the first touch, evidently laid there all at the same time, just after death, and probably numbering at least a thousand. In vain one conjectures the reason of such wholesale burial--one of Nero's massacres, perhaps, or a plague. No one can tell. The invaluable Baracconi, often quoted, recalls the fact that Tasso, when a child, lived with his father in some house on the Monte Cavallo, when the execrable Carafa cardinal and his brother had temporarily succeeded in seizing all the Colonna property; and he gives a letter of Bernardo, the poet's father, written in July to his wife, who was away just then.
