Subsequent to 1409, the latest epoch of the paintings of Lippo, the Bolognese School began to decline; nor could it well be otherwise. Dalmatio, an instructor of youth, was not by profession a painter of history; and, as portrait painters never particularly promoted the progress of any school, so on his part he conferred little benefit on his own. This decline has been attributed to some specimens of art brought from Constantinople, overcharged with dark lines in the contours and folds, and in the remaining parts resembling rather the dryness and inelegance of the Greek mosaic-workers, than the softness and grace then sought to be introduced by the most eminent Italians in the art. Copies of these were eagerly inquired for in Bologna, and in all adjacent cities, which produced that abundance of them, still to be seen in the sale shops and private houses throughout those districts, besides several in the city and state of Venice.[5] But, in these instances, they were only copied; in Bologna they were imitated likewise by several pupils of Lippo, who, either in part or altogether, adopted that style in their own compositions. One Lianori, usually inscribing his name _Petrus Joannis_, and known by some works interspersed in different churches and collections, is most accused of this extravagance; an Orazio di Jacopo, (perhaps dell'Avanzi) of whom there remains a portrait of S. Bernardino, at the church of the Osservanza; a Severo da Bologna, to whom is ascribed a rude altar-piece, in the Malvezzi Museum; with several others, either little known or unmentioned, whose names I am not surprised should be omitted by Vasari, who, in the same way, passes over the least distinguished of his own country. It is true, he makes mention of one Galante da Bologna, who, he avers, designed better than Lippo, his master; but in this he is still taken to task by Malvasia, who includes Galante among the inferior pupils of Dalmasio.
