"One never finishes learning about art. There are always new things to discover. Great works of art seem to look different every time one stands before them. They seem to be as inexhaustible and unpredictable as real human beings."

“The beginning of the sixteenth century, the Cinquecento, is the most famous period of Italian art, one of the greatest periods of all time. This was the time of Leonardo da Vinci and Michelangelo, of Raphael and Titian, of Correggio and Giorgione, of Dürer and Holbein in the north, and of many other famous masters. One may well ask why it was that all these great masters were born in the same period, but such questions are more easily asked than answered. One cannot explain the existence of genius. It is better to enjoy it.”

“The true miracle of the language of art is not that it enables the artist to create the illusion of reality. It is that under the hands of a great master the image becomes translucent. In teaching us to see the visible world afresh, he gives us the illusion of looking into the invisible realms of the mind - if only we know, as Philostratus says, how to use our eyes.”

“There really is no such thing as Art. There are only artists.”

“Whether we know it or not, we always approach the past with some preconceived ideas, with a rudimentary theory we wish to test. In this as in many other respects the cultural historian does not differ all that much from his predecessor, the traveller to foreign lands. Not the professional traveller who is only interested in one particular errand, be it the exploration of a country’s kinship system or its hydroelectric schemes, but the broad-minded traveller who wants to understand the culture of the country in which he finds himself.”

“Anyone who can handle a needle convincingly can make us see a thread which is not there.”

“Like art, science is born of itself, not of nature. There is no neutral naturalism. The artist, no less than the writer, needs a vocabulary before he can embark on a 'copy' of reality.”
