There is a most instructive study of faces in the portraits of the Austrian line. First comes Charles V., the First of Spain, painted by Titian at Augsburg, on horseback, in the armor he wore at Muhl-berg, his long lance in rest, his visor up over the eager, powerful face,--the eye and beak of an eagle, the jaw of a bull-dog, the face of a born ruler, a man of prey. And yet in the converging lines about the eyes, in the premature gray hair, in the nervous, irritable lips, you can see the promise of early decay, of an age that will be the spoil of superstition and bigotry. It is the face of a man who could make himself emperor and hermit. In his son, Philip II., the soldier dies out and the bigot is intensified. In the fine portrait by Pantoja, of Philip in his age, there is scarcely any trace of the fresh, fair youth that Titian painted as Adonis. It is the face of a living corpse; of a ghastly pallor, heightened by the dull black of his mourning suit, where all passion and feeling have died out of the livid lips and the icy eyes. Beside him hangs the portrait of his rickety, feebly passionate son, the unfortunate Don Carlos. The forehead of the young prince is narrow and ill-formed; the Austrian chin is exaggerated one degree more; he looks a picture of fitful impulse. His brother, Philip III., we have just seen, fair and inane,--a monster of cruelty, who burned Jews and banished Moors, not from malice, but purely from vacuity of spirit; his head broadens like a pine-apple from the blond crest to the plump jowls. Every one knows the head of Philip IV.,--he was fortunate in being the friend of Velazquez,--the high, narrow brow, the long, weak face, the yellow, curled mustache, the thick, red lips, and the ever lengthening Hapsburg chin. But the line of Austria ends with the utmost limit of caricature in the face of Charles the Bewitched! Carreno has given us an admirable portrait of this unfortunate,--the forehead caved in like the hat of a drunkard, the red-lidded eyes staring vacantly, a long, thin nose absurd as a Carnival disguise, an enormous mouth which he could not shut, the under-jaw projected so prodigiously,--a face incapable of any emotion but fear. And yet in gazing at this idiotic mask you are reminded of another face you have somewhere seen, and are startled to remember it is the resolute face of the warrior and statesman, the king of men, the Kaiser Karl. Yes, this pitiable being was the descendant of the great emperor, and for that sufficient reason, although he was an impotent and shivering idiot, although he could not sleep without a friar in his bed to keep the devils away, for thirty-five years this scarecrow ruled over Spain, and dying made a will whose accomplishment bathed the Peninsula in blood. It must be confessed this institution of monarchy is a luxury that must be paid for.
