Eventually we must endeavour to grasp Michelangelo's work in the Sistine as a whole, although it was carried out at distant epochs of his life. For this reason I have thrown these sentences forward, in order to embrace a wide span of his artistic energy (from May 10, 1508, to perhaps December 1541). There is, to my mind, a unity of conception between the history depicted on the vault, the prophets and forecomers on the pendentives, the types selected for the spandrels, and the final spectacle of the day of doom. Living, as he needs must do, under the category of time, Michelangelo was unable to execute his stupendous picture-book of human destiny in one sustained manner. Years passed over him of thwarted endeavour and distracted energies--years of quarrying and sculpturing, of engineering and obeying the vagaries of successive Popes. Therefore, when he came at last to paint the Last Judgment, he was a worn man, exhausted in services of many divers sorts. And, what is most perplexing to the reconstructive critic, nothing in his correspondence remains to indicate the stages of his labour. The letters tell plenty about domestic anxieties, annoyances in his poor craftsman's household, purchases of farms, indignant remonstrances with stupid brethren; but we find in them, as I have said, no clue to guide us through that mental labyrinth in which the supreme artist was continually walking, and at the end of which he left to us the Sistine as it now is. VII The old reckoning of the time consumed by Michelangelo in painting the roof of the Sistine, and the traditions concerning his mode of work there, are clearly fabulous. Condivi says: "He finished the whole in twenty months, without having any assistance whatsoever, not even of a man to grind his colours." From a letter of September 7, 1510, we learn that the scaffolding was going to be put up again, and that he was preparing to work upon the lower portion of the vaulting. Nearly two years elapse before we hear of it again. He writes to Buonarroto on the 24th of July 1512: "I am suffering greater hardships than ever man endured, ill, and with overwhelming labour; still I put up with all in order to reach the desired end." Another letter on the 21st of August shows that he expects to complete his work at the end of September; and at last, in October, he writes to his father: "I have finished the chapel I was painting. The Pope is very well satisfied." On the calculation that he began the first part on May 10, 1508, and finished the whole in October 1512, four years and a half were employed upon the work. A considerable part of this time was of course taken up with the preparation of Cartoons; and the nature of fresco-painting rendered the winter months not always fit for active labour. The climate of Rome is not so mild but that wet plaster might often freeze and crack during December, January, and February. Besides, with all his superhuman energy, Michelangelo could not have
