If Vignola did much to make authoritative the later ideas of the sixteenth century as to the principles of ancient art and their application to modern uses, Palladio did even more. By the example of his numerous architectural works, as well as by his writings, the influence on modern art of this famous neo-classicist has been greater than that of any other architect of the Renaissance, so that we have, in the principal countries of Europe, a style of architecture which is known as Palladian. Palladio was the first architect of the Renaissance who was not at any time either a painter or a sculptor. He begins his well-known book[85] as follows: “Guided by natural inclination, I began in my earliest years to devote myself to the study of architecture, and having been always of the opinion that the ancient Romans were in building, as in many other things, far in advance of all those who came after them, I took for my master and guide Vitruvius, who is the only ancient writer on this art, and I set myself to the investigation of the remains of the ancient edifices which, injured by time and the violence of barbarians, are still extant. And finding them much more worthy of attention than I at first thought, I began with great diligence to measure most minutely every part of them. I became so ardent an investigator, not having known with what judgment and fine proportion they had been wrought, that not once only, but many times, I visited different parts of Italy and elsewhere, in order to understand and delineate them completely. And seeing how far the common manner of building differs from what I have observed in the ancient edifices, and read in Vitruvius, and in Leon Batista Alberti, and in other excellent writers since Vitruvius, and from that new manner which I have practised with much satisfaction, and which has been praised by those who profited by my work, it has seemed to me right, since man is not born for himself alone, but also to be useful to others, to publish the drawings of these edifices, which at the cost of much time and peril I have gathered; and to state briefly that which has seemed to me most worthy of consideration in them, together with those rules which I have observed, to the end that those who shall read my book may profit by such good as may be in it, and supply that which may be wanting (for much, perhaps, may be) so that, little by little, we may correct the strange abuses, the barbarous inventions, avoid the superfluous cost, and (what is more important) the various and continued deterioration which we see in so many buildings.” The implicit confidence of the neo-classicists in the art of Roman antiquity as the embodiment of all true principles of architectural design, and their unquestioning belief that mediæval art was wholly false in principle and barbaric in character, have seldom been more naïvely expressed.
