Cimabue was one of the leading protagonists of the renewal of painting that characterized the passage from the 13th to the 14th century in Italy. Although trained in the illustrious tradition of Byzantine art, he brought a new expressivity and use of space to his compositions. He certainly was one of the authors of the mosaic decoration in the baptistery of Florence. Among the masterpieces by him in the city are the Crucifix of Santa Croce and the Maestà in the Uffizi. Leonardo mentions that Cimabue was the maestro of Giotto.
