Of a very different type was his companion, Julius Burger. He came of a curious blend, a German father and an Italian mother, with the robust qualities of the North mingling strangely with the softer graces of the South. Blue Teutonic eyes lightened his sun-browned face, and above them rose a square, massive forehead, with a fringe of close yellow curls lying round it. His strong, firm jaw was clean-shaven, and his companion had frequently remarked how much it suggested those old Roman busts which peered out from the shadows in the corners of his chamber. Under its bluff German strength there lay always a suggestion of Italian subtlety, but the smile was so honest, and the eyes so frank, that one understood that this was only an indication of his ancestry, with no actual bearing upon his character. In age and in reputation, he was on the same level as his English companion, but his life and his work had both been far more arduous. Twelve years before, he had come as a poor student to Rome, and had lived ever since upon some small endowment for research which had been awarded to him by the University of Bonn. Painfully, slowly, and doggedly, with extraordinary tenacity and single-mindedness, he had climbed from rung to rung of the ladder of fame, until now he was a member of the Berlin Academy, and there was every reason to believe that he would shortly be promoted to the Chair of the greatest of German Universities. But the singleness of purpose which had brought him to the same high level as the rich and brilliant Englishman, had caused him in everything outside their work to stand infinitely below him. He had never found a pause in his studies in which to cultivate the social graces. It was only when he spoke of his own subject that his face was filled with life and soul. At other times he was silent and embarrassed, too conscious of his own limitations in larger subjects, and impatient of that small talk which is the conventional refuge of those who have no thoughts to express.
