Cenni di Pepo (Giovanni) Cimabue also known as Bencivieni Di Pepo or in modern Italian, Benvenuto Di Giuseppe, was an Italian painter and creator of mosaics from Florence. He is also well known for his student Giotto, who revolutionized painting in Italy. Cimabue is generally regarded as the last great painter working in the Byzantine tradition. The art of this period comprised scenes and forms that appeared relatively flat and highly stylized. Wikipedia
