Thus far have I thought fit to discourse from the beginning of sculpture and of painting, and peradventure at greater length than was necessary in this place, which I have done, indeed, not so much carried away by my affection for art as urged by the common benefit and advantage of our craftsmen. For having seen in what way she, from a small beginning, climbed to the greatest height, and how from a state so noble she fell into utter ruin, and that, in consequence, the nature of this art is similar to that of the others, which, like human bodies, have their birth, their growth, their growing old, and their death; they will now be able to recognize more easily the progress of her second birth and of that very perfection whereto she has risen again in our times. And I hope, moreover, that if ever (which God forbid) it should happen at any time, through the negligence of men, or through the malice of time, or, finally, through the decree of Heaven, which appears to be unwilling that the things of this earth should exist for long in one form, that she falls again into the same chaos of ruin; that these my labours, whatsoever they may be worth (if indeed they may be worthy of a happier fortune), both through what has been already said and through what remains to say, may be able to keep her alive or at least to encourage the most exalted minds to provide them with better assistance; so much so that, what with my good will and the works of these masters, she may abound in those aids and adornments wherein, if I may freely speak the truth, she has been wanting up to the present day.
