126. But it is not only the fixed nature of the successive steps which influenced the character of these early painters. A peculiar _direction_ was given to their efforts by the close attention to drawing which, as Mr. Eastlake has especially noticed, was involved in the preparation of the design on the white ground. That design was secured with a care and finish which in many instances might seem altogether supererogatory.[18] The preparation by John Bellini in the Florentine gallery is completed with exhaustless diligence into even the portions farthest removed from the light, where the thick brown of the shadows must necessarily have afterwards concealed the greater part of the work. It was the discipline undergone in producing this preparation which fixed the character of the school. The most important part of the picture was executed not with the brush, but with the point, and the refinements attainable by this instrument dictated the treatment of their subject. Hence the transition to etching and engraving, and the intense love of minute detail, accompanied by an imaginative communication of dignity and power to the smallest forms, in Albert Duerer and others. But this attention to minutiae was not the only result; the disposition of light and shade was also affected by the method. Shade was not to be had at small cost; its masses could not be dashed on in impetuous generalization, fields for the future recovery of light. They were measured out and wrought to their depths only by expenditure of toil and time; and, as future grounds for color, they were necessarily restricted to the _natural_ shadow of every object, white being left for high lights of whatever hue. In consequence, the character of pervading daylight, almost inevitably produced in the preparation, was afterwards assumed as a standard in the painting. Effectism, accidental shadows, all obvious and vulgar artistical treatment, were excluded, or introduced only as the lights became more loaded, and were consequently imposed with more facility on the dark ground. Where shade was required in large mass, it was obtained by introducing an object of locally dark color. The Italian masters who followed Van Eyck's system were in the constant habit of relieving their principal figures by the darkness of some object, foliage, throne, or drapery, introduced behind the head, the open sky being left visible on each side. A green drapery is thus used with great quaintness by John Bellini in the noble picture of the Brera Gallery; a black screen, with marbled veins, behind the portraits of himself and his brother in the Louvre; a crimson velvet curtain behind the Madonna, in Francia's best picture at Bologna. Where the subject was sacred, and the painter great, this system of pervading light produced pictures of a peculiar and tranquil majesty; where the mind of the painter was irregularly or frivolously imaginative, its temptations to accumulative
