It was in connection with the Duomo that the architect reminded me of the celebrated story about Brunelleschi. When the Florentine church authorities decided to build the Duomo they were puzzled as to how so mighty a dome should be developed. So they invited the architects to appear before them in competition, and to present their ideas. One architect, Donatello, explained that, if he secured the commission, he should first build a mound of earth, and over it he would construct his dome. But the authorities replied that there would be great labor and expense in taking the earth out. He said that he would put coins into the earth and, by this means, he would very quickly have the earth removed by the people. When Brunelleschi was asked how he would build his dome he said: "How would you make an egg stand on end?" They didn't know how, and he showed them, by taking a hard-boiled egg and pressing it down at one end, an idea like the one that occurred to Christopher Columbus about fifty years later. The Palace of Horticulture as an illustration of French Renaissance architecture fascinated this observer, in spite of its overelaborateness. "It's marvelous to think of what the Renaissance meant throughout Europe," he said, "and how it showed itself in art through the national characteristics. French Renaissance and Italian Renaissance, though they have qualities in common, are very different. And you'll find marked differences even in the Renaissance art of the Italian cities, such as Rome and Florence and Venice. But the Renaissance showed that no matter how far apart the people of Europe might have been they were all stirred by a great intellectual and spiritual movement. It was like a vast moral earthquake. It meant the rediscovery and the joyous recognition of the relation of the past to the present and the meaning of the relation for mankind. It led to a new kind of self-emancipation and individualism. It created art-forms that have stamped themselves on the work all over these grounds. In a sense it was a declaration of artistic independence." "Is there really such a thing as independence in art?" I ventured to ask. The architect began to smile. "I'm afraid there isn't much independence. If there were this Exposition would not be quite so intimately related to Europe and the Orient. But wait till we get into Mullgardt's Court of the Ages. Then you'll find an answer to your question."
