will cost less than those of Carrara; but, even should they cost more, his Holiness is firmly resolved to act as I have said, furthering the business of Pietra Santa for the public benefit of the city. Look to it, then, that you carry out in detail all that we have ordered without fail; for if you do otherwise, it will be against the expressed wishes of his Holiness and ourselves, and we shall have good reason to be seriously wroth with you. Our agent Domenico (Buoninsegni) is bidden to write to the same effect. Reply to him how much money you want, and quickly, banishing from your mind every kind of obstinacy." Michelangelo began to work with his usual energy at roadmaking and quarrying. What he learned of practical business as engineer, architect, master of works, and paymaster during these years among the Carrara mountains must have been of vast importance for his future work. He was preparing himself to organise the fortifications of Florence and the Leonine City, and to crown S. Peter's with the cupola. Quarrying, as I have said, implied cutting out and rough-hewing blocks exactly of the right dimensions for certain portions of a building or a piece of statuary. The master was therefore obliged to have his whole plan perfect in his head before he could venture to order marble. Models, drawings made to scale, careful measurements, were necessary at each successive step. Day and night Buonarroti was at work; in the saddle early in the morning, among stone-cutters and road-makers; in the evening, studying, projecting, calculating, settling up accounts by lamplight. VI The narrative of Michelangelo's personal life and movements must here be interrupted in order to notice an event in which he took no common interest. The members of the Florentine Academy addressed a memorial to Leo X., requesting him to authorise the translation of Dante Alighieri's bones from Ravenna to his native city. The document was drawn up in Latin, and dated October 20, 1518. Among the names and signatures appended, Michelangelo's alone is written in Italian: "I, Michelangelo, the sculptor, pray the like of your Holiness, offering my services to the divine poet for the erection of a befitting sepulchre to him in some honourable place in this city." Nothing resulted from this petition, and the supreme poet's remains still rest beneath "the little cupola, more neat than solemn," guarded by Pietro Lombardi's half-length portrait.
