Andrea del Castagno (c. 1422 Castagno near Florence-1457 Florence), whose actual name was andrea di Bartolo, was probably a pupil of the provincial painter Paolo Schiavo. Sources seem to indicate that in the late 1430s he was introduced into florentine artistic circles as the protege of Bernadetto de Medici. Inspired by Masaccio and in particular by the sculptor Donatello (1386-1466), he developed a markedly individual style that would have a great influence on Florentine painters. Andrea's works are characterized by shapely - drawn, muscular, dynamic figures whose physicality is heightened by a clear use of perspective and a reduction of spatial elements. In some paintings, however, the figures massiveness is moderated by the artist's use of lighting, a broad application of colour, or the individual characteristics of the figures. Among his major works are God the Father with Saints, c. 1422, San Zaccharia, Florence; The Assumption of Christ 1449/50, Gemaldegaleries, SMPK, Berlin; and The Crucifixion, c. 1456, Santa Maria Degli Angeli, Florence.
