This picture has at different times been given several different attributions, of which the most cautious was "School of Bellini." In earlier editions of the Official Catalogue it was ascribed to Basaiti (see 281); but now (1898) to Bellini. Sir Edward Poynter refers in support of this alteration to the close resemblance of the present picture to a signed work by Bellini in the Giovanelli Palace at Venice, and, as regards the background, to No. 812 in our gallery. Sir Walter Armstrong (_Notes on the National Gallery_, p. 24) draws attention to the similarity in the baby's hands here and in 224, and would ascribe both pictures to Catena. The correct settlement of disputed points of attribution like this is highly important for the history of painting, but meanwhile the very fact of such disputes has a useful significance, as showing what is meant by the old "schools" of painting. Individual peculiarities are only discovered by minutest examinations; but beneath such differences there are in each school similarities of treatment and conception which come from common traditions and common teaching, and which cause critics of equal intelligence to attribute the same pictures to different masters of the school. 600. THE BLIND BEGGAR. _J. L. Dyckmans_ (Flemish: 1811-1888). Josef Laurens Dyckmans, a pupil of Wappers, was for some time Professor of the Academy of Painting at Antwerp. "A blind old man is standing in the sunshine by a church door: before him is a young girl, who is holding out her hand for alms to the passers-by; an old lady coming from the church is feeling in her pocket for a sou; some other figures are seen in the porch at their devotions before a crucifix. Painted at Antwerp, signed _J. Dyckmans_, 1853" (Official Catalogue). "The picture is painted in a tone of colour exceedingly low, but the whole is worked to an extreme finish; the heads in fact are elaborated with a care such as Denner's pictures show. In these days of light and glowing harmonies the eye is at once struck with the abstinence from colour which the artist has made a cardinal principle in the execution of his work" (_Art Journal_, July 1864). This picture was presented by Miss Jane Clark, who paid 900 guineas for it. 602. A "PIETÀ." _Carlo Crivelli_ (Venetian: painted 1468-1493).
