indolence, any impatience, or whatever else it might be that had otherwise stamped a personal character on their work; and all remonstrance must have been shamed by the evident fact that the young master spared himself not a whit more. The perseverance and docility which made such engraving possible was perhaps the greatest aid that Dürer drew from German character; it was not only an aid, but an example to and restraint upon that haughty spirit of his that restively ever again vows never to take so much pains over another picture to be so poorly paid (see page 103); that complains of failure and discouragement after years of repeatedly more world-wide successes (see page 187). These are not German traits, but it may have been the German blood he inherited from his mother and the example of his friends, fellow-workers, and helpers, which enabled him to get the better of such petulant and gloomy outbursts, and return to the day of small things with the will to continue and endure. The difference introduced by the engravers becoming more and more capable of rendering Dürer's hand is well illustrated by comparing the frontispiece to the _Apocalypse_, added about 1511, with the other cuts which had appeared in 1498. Doubtless Dürer's hand had changed its character considerably during this period of constant and rapid development, and it requires tact and knowledge to separate the differences due to the creator from those due to the engraver. Dürer's drawings differed as widely from the earlier drawings as does the engraving from the earlier blocks. But, as we may see by early drawings done as preliminary studies for engravings, the method of his pen strokes had changed less than the character of the forms they rendered; the conception of the design as a whole had advanced more rapidly than the skill and sleight of hand which expressed it. The engraver has by 1511 become capable of expressing a greater variety of speed in the stroke, makes it taper more finely, and can follow the tongue-like lap and flicker as the pen rises and dips again before leaving the surface of the block (as in the outer ends of the strokes that represent the radiance of the Virgin's glory). Holbein, later on, was to obtain a yet more wonderful fidelity from Lutzelburger, the engraver of his _Dunce of Death_.
