There is one, among the four pictures ascribed to Fra Angelico in this collection, from which something of the heavenly purity, the sweetness, and the tenderness of this great and gentle master may be learned. It is a picture of the Last Judgment. Unfortunately, it has been much injured by time and by neglect; its brilliant colors have sunk and become dim,--those pure, clear colors which give to Fra Angelico's panel pictures the brilliancy of a missal illumination, and which reflect the purity and the clearness of his tranquil life and his reverential soul. It is no fanciful theory which connects the uses of color with moral qualities, and which from the coloring of a picture will deduce something of the moral character of its painter. Thus it is not only from the exquisite delicacy of form, the spirituality of expression, and the sweet, reverent fancy in attitude, of the angels from which Fra Angelico derived his name, but also from the brightness of their golden wings, from the deep glow of their crimson, or scarlet, or azure robes, and from the clear shining of the stars on their foreheads, that one learns that he deserved that name as characteristic of his temper and his life. Something of the influence of the cloister shows itself in most of his larger works; but if his vision was narrowed within convent walls, it did but pierce the more clearly into the regions of tranquillity and loveliness that lay above them. With the end of the fifteenth century religion almost disappears from Art. John Bellini, dying ninety years old in 1516, was the last and one of the greatest of the long line of artists who had loved Art as the means granted them of serving God upon earth. The manly vigor of his conceptions, the tender and holy purity of his imagination, the delicate strength of his fancy, are not to be discovered in the few pictures that bear his name at Manchester. His pictures are to be fairly seen only at Venice, where, in out-of-the-way churches, over tawdry altars, his colors gleam undimmed by time, and the faces of his Virgins look down with a still celestial sweetness. But there is one picture here, by a Venetian contemporary of John Bellini, before which we shall do well to pause. It is a St. Catharine, by Cima da Conegliano. It is the picture of a noble woman, full of fortitude, serenity, and faith. The richness of the color of her dress, her calm dignity, the composure of her attitude, recall to mind and make her the worthy companion of the beautiful St. Barbara of the church of Santa Maria Formosa. It is well to look at her, for we are coming to those days when such saints as these were no longer painted; but in their places whole tribes of figures with faces twisted into every trick of sentimental devotion, imbecile piety, and pretended fervor.
