Observe then, this Puritanism in the worship of beauty, though sometimes weak, is always honourable and amiable, and the exact reverse of the false Puritanism, which consists in the dread or disdain of beauty.  And in order to treat my subject rightly, I ought to proceed from the skill of art to the choice of its subject, and show you how the moral temper of the workman is shown by his seeking lovely forms and thoughts to express, as well as by the force of his hand in expression.  But I need not now urge this part of the proof on you, because you are already, I believe, sufficiently conscious of the truth in this matter, and also I have already said enough of it in my writings; whereas I have not at all said enough of the infallibleness of fine technical work as a proof of every other good power.  And indeed it was long before I myself understood the true meaning of the pride of the greatest men in their mere execution, shown for a permanent lesson to us, in the stories which, whether true or not, indicate with absolute accuracy the general conviction of great artists;—­the stories of the contest of Apelles and Protogenes[184] in a line only, (of which I can promise you, you shall know the meaning to some purpose in a little while),—­the story of the circle of Giotto,[185] and especially, which you may perhaps not have observed, the expression of Duerer in his inscription on the drawings sent him by Raphael.  These figures, he says, “Raphael drew and sent to Albert Duerer in Nurnberg, to show him”—­What?  Not his invention, nor his beauty of expression, but “sein Hand zu weisen,” “to show him his hand.”  And you will find, as you examine farther, that all inferior artists are continually trying to escape from the necessity of sound work, and either indulging themselves in their delights in subject, or pluming themselves on their noble motives for attempting what they cannot perform; (and observe, by the way, that a great deal of what is mistaken for conscientious motive is nothing but a very pestilent, because very subtle, condition of vanity); whereas the great men always understand at once that the first morality of a painter, as of everybody else, is to know his business; and so earnest are they in this, that many, whose lives you would think, by the results of their work, had been passed in strong emotion, have in reality subdued themselves, though capable of the very strongest passions, into a calm as absolute as that of a deeply sheltered mountain lake, which reflects every agitation of the clouds in the sky, and every change of the shadows on the hills, but AS itself motionless.
