That man was to be Rodin. Although he has been listened to by the ignorant and superficial multitude, it has not been chiefly because of the authority of his genius, of the general renown that he has enjoyed. He has truly thrown a new light over the mystery of Gothic construction. Thanks to him, we understand in a measure, for tangible reasons, the reasons of an actual carver, this "world in little" that constitutes the Gothic cathedrals. What study, what researches are necessary in order to comprehend the art of stonework! Does any one suppose that Rodin himself has attained this in a day? By no means. That lover of perfection in detail does not possess the instantly penetrating glance that is often the property of genius: to the task of deciphering our monuments he brought that slow-minded, customary patience of his, together with his energy. He had first of all to rid himself of the false current ideas. After that thirty years of observation were necessary for him to reach conclusions that satisfied his artistic conscience. Even to-day he is far from affirming that he has understood everything, that he has grasped the full significance of the Gothics. Read his book, "The Cathedrals of France," published in 1914; observe the carefullness of his judgments, the gropings of his thought, the constant retracing of his steps. He makes attempts, ventures; he never proclaims his opinion in the peremptory tone dear to specialists in criticism, but endeavors to approach respectfully, as closely as possible, to the spirit of the masters. Sometimes a flash of genius springs from his brain and illumines to the depths of its mysteries the Gothic universe; but nothing is suggested that does not spring from a prolonged observation, and when at last he speaks it is in the tone of a man who mistrusts himself. It must be confessed that in this work, "The Cathedrals of France," something is lacking, even though it is prefaced by a long and very learned introduction by one of our good writers, Charles Morice. It lacks the magnificent lesson that the reader will find in these pages, signed with Rodin's name. This lesson constitutes really a vital page that is, as it were, the key and the summary of the whole work; but the master, having given me the first rights in it, had scruples, as had Charles Morice, about including it in his own book. Before obtaining this page, with what insistence did I have to question Rodin not once, not twice, but twenty times, during the course of a number of years. Every time he came back from one of his pilgrimages to some old city of the provinces, to our churches, our town halls, I renewed my questions without receiving any satisfactory answer. In my heart I could not but honor this rigorous honesty which was unwilling to venture anything lightly on so vast, so noble a subject.
