On his return to Rome, Michael Angelo wished to have resumed his work on the mausoleum; but the pope had resolved on the completion of the Sistine Chapel; he commanded Michael Angelo to undertake the decoration of the vaulted ceiling; and the artist was obliged, though reluctantly, to obey. At this time the frescos which Raphael and his pupils were painting in the chambers of the Vatican had excited the admiration of all Rome. Michael Angelo, who had never exercised himself in the mechanical part of the art of fresco, invited from Florence several painters of eminence, to execute his designs under his own superintendence; but they could not reach the grandeur of his conceptions, which became enfeebled under their hands, and one morning, in a mood of impatience, he destroyed all that they had done, closed the doors of the chapel against them, and would not thenceforth admit them to his presence. He then shut himself up, and proceeded with incredible perseverance and energy to accomplish his task alone; he even prepared his colors with his own hands. He began with the end toward the door, and in the two compartments first painted (though not first in the series), the "Deluge," and the "Vineyard of Noah;" he made the figures too numerous and too small to produce their full effect from below, a fault which he corrected in those executed subsequently. When almost half the work was completed, the pope insisted on viewing what was done, and the astonishment and admiration it excited rendered him more and more eager to have the whole completed at once. The progress, however, was not rapid enough to suit the impatient temper of the pontiff. On one occasion he demanded of the artist _when_ he meant to finish it; to which Michael Angelo replied calmly, "When I can." "When thou canst!" exclaimed the fiery old pope, "thou hast a mind that I should have thee thrown from the scaffold!" At length, on the day of All Saints, 1512, the ceiling was uncovered to public view. Michael Angelo had employed on the painting only, without reckoning the time spent in preparing the cartoons, twenty-two months, and he received in payment three thousand crowns. The collection of engravings after Michael Angelo in the British Museum is very imperfect, but it contains some fine old prints from the Prophets which should be studied by those who wish to understand the true merit of this great master, of whom Sir Joshua Reynolds said that, "to kiss the hem of his garment, to catch the slightest of his perfections, would be glory and distinction enough for an ambitious man!" When the Sistine Chapel was completed Michael Angelo was in his thirty-ninth year; fifty years of a glorious though troubled career were still before him.
