Behold, seventeen years since I first presented to your most Illustrious Excellency the Lives, sketched so to speak, of the most famous painters, sculptors and architects, they come before you again, not indeed wholly finished, but so much changed from what they were and in such wise adorned and enriched with innumerable works, whereof up to that time I had been able to gain no further knowledge, that from my endeavour and in so far as in me lies nothing more can be looked for in them. Behold, I say, once again they come before you, most Illustrious and truly most Excellent Lord Duke, with the addition of other noble and right famous craftsmen, who from that time up to our own day have passed from the miseries of this life to a better, and of others who, although they are still living in our midst, have laboured in these professions to such purpose that they are most worthy of eternal memory. And in truth it has been no small good-fortune for many that I, by the goodness of Him in whom all things have their being, have lived so long that I have almost rewritten this book; seeing that, even as I have removed many things which had been included I know not how, in my absence and without my consent, and have changed others, so too I have added many, both useful and necessary, that were lacking. And as for the likenesses and portraits of so many men of worth which I have placed in this work, whereof a great part have been furnished by the help and co-operation of your Excellency, if they are sometimes not very true to life, and if they all have not that character and resemblance which the vivacity of colours is wont to give them, that is not because the drawing and the lineaments have not been taken from the life and are not characteristic and natural; not to mention that a great part of them have been sent me by the friends that I have in various places, and they have not all been drawn by a good hand. Moreover, I have suffered no small inconvenience in this from the distance of those who have engraved these heads, because, if the engravers had been near me, it might perchance have been possible to use in this matter more diligence than has been shown. But however this may be, our lovers of art and our craftsmen, for the convenience and benefit of whom I have put myself to so great pains, must be wholly indebted to your most Illustrious Excellency for whatever they may find in it of the good, the useful, and the helpful, seeing that while engaged in your service I have had the opportunity, through the leisure which it has pleased you to give me and through the management of your many, nay, innumerable treasures, to put together and to give to the world everything which appeared to be necessary for the perfect completion of this work; and would it not be almost impiety, not to say ingratitude, were I to dedicate these Lives to another, or were the craftsmen to attribute to any other than yourself whatever they may
