The same sharp division of taste among those who practise an art, somewhat smoothed over and blurred by those who subsequently comment on it, is illustrated (it seems to me) by the history of Gothic architecture. All know well the spectacle of some great cathedral slowly grown to completion through the labours of successive generations. We neither find, nor expect to find, that the original design has been followed throughout. On the contrary, each succeeding school has built its share of work in its own style. The fourteenth-century architect does nothing as it would have been done could the twelfth-century architect have had his way; and the fifteenth century treats the fourteenth, as the fourteenth treated its predecessors. We praise the mixed result, and doubtless we do well. But we make, I believe, a great mistake if we attribute to the mediaeval artists our own mood of universal, if somewhat ineffectual, admiration.

They thought well of themselves and poorly of their forefathers. They had the intolerance which so often accompanies real creative power. This at least is my conjecture. What is not a matter of conjecture but of certainty is the way in which the different
