Distinguished by the aesthetic quality of his works and the significance of his patrons, Benedetto da Maiano (1442-1497) is one of the most important Italian sculptors in the fifteenth century. As the teacher of Michelangelo, he paved the way for High Renaissance sculpture. However, his importance has not yet been realized. This monograph covers the entire known career of this neglected artist, and includes not only a study of the style and meaning of his works, but also their historical and political contexts. A number of works recently discovered by the author are presented for the first time; works which did not survive in their original form are reconstructed, and the hitherto unknown patrons of many of da Maiano's works are identified. This two-volume set, consisting of a text and an illustration volume, is based upon many new documents discovered by the author concerning the life of Benedetto, his estate, the workshop inventories, the commissions of his works and the way they were realized. These documents contribute to a new picture not only of the artistic development and social context of the artist, but to Florentine art in the Quattrocento, as well.
