CASTAGNO, ANDREA DEL Italian painter of the Florentine school, was born in 139o, probably at Castagno, in the district of Mugello, and died in Aug. 1457. He imitated Masaccio and the naturalists of his time in boldness of attitude. The charge that he treacherously assassinated his colleague, Do menico Veneziano, in order to monopolize the then recent secret of oil painting as practised in Flanders by the Van Eycks, has been proved to be untrue. Domenico died four years after Andrea. The latter is commonly called "Andrea (or Andreino) degl' Im piccati" (of the hanged men), in consequence of his being com missioned in 1435 to paint, in the Palazzo del Podesta in Florence, the fallen leaders of the Peruzzi and Albizzi. One of his principal works now extant (most of them have perished) is the equestrian figure of Nicola di Tolentino, in the cathedral of Florence.
