Orcagna

Andrea di Cione di Arcangelo (c. 1308 – 25 August 1368), better known as Orcagna, was an Italian painter, sculptor, and architect active in Florence. He worked as a consultant at the Florence Cathedral and supervised the construction of the façade at the Orvieto Cathedral. His Strozzi Altarpiece (1354–57) is noted as defining a new role for Christ as a source of Catholic doctrine and papal authority.
