It is very interesting to follow the progress of the work in Grimaldi's diary, to witness with him the opening and destruction of every tomb worthy of note, and to make the inventory of its contents. The monuments were mostly pagan sarcophagi, or bath basins, cut in precious marbles; the bodies of Popes were wrapped in rich robes, and wore the "ring of the fisherman" on the forefinger. Innocent VIII., Giovanni Battista Cibo (1484-1492), was folded in an embroidered Persian cloth; Marcellus II., Cervini (1555), wore a golden mitre; Hadrian IV., Breakspeare (1154-1159), is described as an undersized man, wearing slippers of Turkish make, and a ring with a large emerald. Callixtus III. and Alexander VI., both of the Borgia family, have been twice disturbed in their common grave: the first time by Sixtus V., when he removed the obelisk from the spina of the circus to the piazza; the second by Paul V. on Saturday, January 30, 1610, when their bodies were removed to the Spanish church of Montserrat, with the help of the marquis of Billena, ambassador of Philip III., and of cardinal Çapata. Grimaldi asserts that Michelangelo's plan of a Greek cross had not only been designed on paper, but actually begun. When Pope Borghese and Carlo Maderno determined upon the Latin cross, not only the foundations of the front had been finished according to Michelangelo's design, but the front itself, with its coating of travertine, had been built to the height of several feet. The construction of the dome was begun on Friday, July 15, 1588, at 4 P. M. The first block of travertine was placed _in situ_ at 8 P. M. of the thirtieth. The cylindrical portion or drum (_tamburo_) which supports the dome proper was finished at midnight of December 17, of the same year, a marvellous feat to have accomplished. The dome itself was begun five days later, and finished in seventeen months. If we remember that the experts of the age had estimated ten years as the time required to accomplish the work, and one million gold scudi as the cost, we wonder at the power of will of Sixtus V., who did it in two years and spent only one fifth of the stated sum.[85] He foresaw that the political persecution from the crown of Spain and the daily assaults, almost brutal in their nature, which he had to endure from count d'Olivare, the Spanish ambassador, would shorten his days, and consequently manifested but one desire: that the dome and the other great works undertaken for the embellishment and sanitation of the city should be finished before his death. Six hundred skilled craftsmen were enlisted to push the work of the dome night and day; they were excused from attending divine service on feast days, Sundays excepted. We may form an idea of the haste felt by all concerned in the enterprise, and of their determination to sacrifice all other interests to speed, by the following anecdote.
