These artists, before the Renaissance, painted in the style of Greek icons. Their paintings were important to the education of many Renaissance painters, and were to be seen in the churches where the Renaissance painters worked, and worshipped. Often an altarpiece by one of these artists was surrounded by frescoes by the Renaissance painters who lived 150 to 200 years later. A famous "Madonna and Child" by Coppo di Marcovaldo stood above the altar where Masaccio, Masolino and Filippo Lippi painted the walls of the Brancacci Chapel. Giotto, who is thought of as the first Renaissance painter, was educated by Cimabue, one of the great masters of the Late Byzantine style.
