For we must keep constantly in mind that what we call the Middle Ages or--worse yet--the Dark Ages, made up the Yesterday of the Holbeins and was the flesh and blood transmitted to them as their own flesh and blood with all its living bonds toward the Old and all its living impulses toward the New. A now famous New Zealander is, we know, to sketch our own "mediaevalism" with contemptuous pity for its darkness. But until his day comes, our farthing-dips seem to make a gaudy illumination. And, meantime, we are alive; we walk about; we, too, can swell the chorus which the Initiated chant in every century with the same fond confidence: "We alone enjoy the Holy Light." The New is ever becoming old; the old ever changing into New. And if we ask why each waxes or wanes just when it does and as it does, there is, in the last analysis, no better answer than Aurora's explanation for chancing on the poets-- _Because the time was ripe._ And the Holbein century is one of stupendous Transitions because the time was ripe; and not simply because printing was invented, or Greek scholars were driven from Constantinople to scatter abroad in Europe, or Ferdinand and Isabella wanted a direct route to Cathay, or Friar Martin nailed ninety-five Theses to the door of Wittenberg's church, and built himself thereby an everlasting name as Luther. And because the time was ripe for a new Art, even more than because this or that great painter entrained it, it also had its transition period, and Holbein is set down in manuals as a transitional painter. Teutonic, too; because all Christian art is either Byzantine or Italian or Teutonic in its type. When it first crept from the catacombs under the protection of the Constantinople Court it could but be Byzantine; that strange composite obtained by stripping the Greek "beast" of every pagan beauty and then decking it out with crude Oriental ornament. But who that prizes the peculiar product of that fanaticism would have had its cradle without this sleepless terror, lest for the whole world of classic heathendom it should lose the dear-bought soul of purely Christian ideals? Or who, remembering that in thus relentlessly sacrificing its entire heritage of pagan accumulation it put back the clock of Art to the Stone Age, and had to begin all over again in the helpless bewilderment of untaught childish effort,--could find twice ten centuries too long for the astounding feat it achieved? Ten centuries, after all, make but a marvellous short course betwixt the archaic compositions of the third century and the compositions of Giotto or Wilhelm Meister.
