The Madonna is colossal. She wears a hood, and holds her child in her arms. There is a strong human, yet spiritualized expression upon the face. The drapery is gracefully arranged, not folded like mummy cloths; and the color is strong and liberally laid on, without any attempt, however, at transparency of shadow. There is little indication of the technical glories of succeeding centuries. Perhaps the best part of the picture is in the lower margin. Here are four heads of saints, painted with a breadth and energy absolutely startling, when one recollects by whom and when they were executed. Dominic Ghirlandaio, two hundred years later, could hardly have put more masculine expression into a quartet of heads. Giotto's Madonna is the pendant to that of Cimabue; but although painted twenty-five years later, it shows less progress in art than might be expected. Giotto's triumphs are to be found in the frescos of the Santa Croce. In that unequalled series, the art-student recognizes, almost at a glance, the power of the master. Largeness, rhythm, and harmony of composition,--dramatic movement, and individual beauty of expression,--heads which have brains, eyes which can smile, lips which can speak, fluent limbs which can move, or remain in natural repose,--the whole surrounded and inspired by that atmosphere of piety, that effluence of religious ecstasy, which can never be imitated, and which came from the unquestioning faith of the artist;--such wonders were for the first time revealed by Giotto. The shepherd boy, whom Cimabue found drawing pictures upon a stone in the open field, nobly repaid his patron and master, by extending still farther the domain of art,--by throwing its doors wide open to the cool breath of nature and the liberal sunshine. To pass from the Byzantines into the school of Giotto is to come out from the catacombs into the warm precincts of the cheerful day. Of the pictures of the early part of the fifteenth century, none are more worthy of attention in this collection than those of Fra Angelico of Fiesole. (1387-1455.) Nevertheless, it seems no great progress from Cimabue, Giotto, and Orgagna, whose compositions are so full of energetic life and human passion, to these careful, gentle miniatures upon an expanded scale. The Fra was a _miniatore_, after all,--a manuscript illuminator of the first class. His effort to represent a descent from the cross in a large and dramatic manner is feeble and flat. This flight seems beyond his strength; and his waxy little wings, which sustained him so well within his own sphere, melted at once in this higher region.
