Pope Julius II, himself one of the great geniuses of history, with a dream of a united Italy long before there was any possibility of its accomplishment, and with an appreciation of genius that alone would have given him a commanding place among the world's great rulers, had summoned to Rome for the decoration of the apartments of the Vatican some of the greatest painters of the time. Even from distant Flanders came Reuisch and then there were Perugino, Raphael's old master, now advanced in years, and Signorelli, quite as old, and Lotto and Sodoma and Peruzzi and others. It was beside these that Raphael had to do his work. Within a year of Raphael's coming he, the youngest of them all, not yet twenty-six years of age, was selected by the Pope--how well advised he was--as the one to whom all the important decorations should be entrusted. Then came the opportunity to do the Camera della Segnatura, that triumph of decorative art. "This chamber of the Vatican" became, as Raphael's biographer in the Catholic Encyclopaedia says, "a sort of mirror of the tendencies of the human mind, a summary of all its ideal history, a sort of pantheon of spiritual grandeurs. Thereby the representation of ideas acquired a dramatic value, being no longer as in the Middle Ages the immovable exposition of an unchangeable truth but the impassioned search for knowledge in all its branches, the moral life of humanity." {8} His decorations of the Camera de la Segnatura are probably among the greatest contributions to decorative art ever made. They are certainly among the most interesting. Only Michelangelo's wonderful decorations in the Sistine Chapel rival them and there are some critics who would concede the palm to Raphael. Here we have the index not only of his power to paint marvellously but also of his intellectual genius and his judgment of values in the history of literature and philosophy. Such pictures as the "Disputa" and the "School of Athens" are real contributions to the history of human thought. Only a man who was himself of profound intellectuality on a plane of equality with the great intellectual geniuses whom he was painting could have conceived and completed these magnificent groups of the world's greatest men successfully. It has been well said that to appreciate properly the pictures of the Segnatura is of itself an education. To be able to take them in their full significance as essays in art and in the history of literature and philosophy is to have gone far on the road to culture. Raphael's achievement here is that of a great mind gifted with a wonderful power of comprehension as well as an almost unrivalled faculty of expression. No decorative pictures of the modern time, however great, can be placed beside them.
