49. And that is God's doing and distributing; and none is rashly to be thought inferior to another, as if by his own fault; nor any of them stimulated to emulation, and changing places with others, although their allotted tasks be of different dignities, and their granted instruments of different keenness; for in none of them can there be a perfection or balance of all human attributes;--the great colorist becomes gradually insensible to the refinements of form which he at first intentionally omitted; the master of line is inevitably dead to many of the delights of color; the study of the true or ideal human form is inconsistent with the love of its most spiritual expressions. To one it is intrusted to record the historical realities of his age; in him the perception of character is subtle, and that of abstract beauty in measure diminished; to another, removed to the desert, or inclosed in the cloister, is given, not the noting of things transient, but the revealing of things eternal. Ghirlandajo and Titian painted men, but could not angels; Duccio and Angelico painted Saints, but could not senators. One is ordered to copy material form lovingly and slowly--his the fine finger and patient will: to another are sent visions and dreams upon the bed--his the hand fearful and swift, and impulse of passion irregular and wild. We may have occasion further to insist upon this great principle of the incommunicableness and singleness of all the highest powers; but we assert it here especially, in opposition to the idea, already so fatal to art, that either the aim of the antique may take place together with the purposes, or its traditions become elevatory of the power, of Christian art; or that the glories of Giotto and the Sienese are in any wise traceable through Niccola Pisano to the venerable relics of the Campo Santo. 50. Lord Lindsay's statement, as far as it regards Niccola himself, is true. * * *
