Bertoldo di Giovanni (
b ?Florence,
c.1430;
d Poggio a Caiano, nr. Florence, 28 Dec. 1491). Florentine sculptor. He was a fairly minor talent, but he is remembered for three things. First, he was the pupil and assistant of
Donatello and briefly the teacher or mentor of
Michelangelo, thus forming a link between the greatest Italian sculptors of the 15th and 16th centuries. Secondly (and relatedly), he was the ‘guide and chief’ (
Vasari) of the informal art
academy that Lorenzo the Magnificent maintained in the
Medici garden near S. Marco (it was there that he knew Michelangelo). Thirdly, he developed a new type of sculpture—the small-scale bronze, intended, like the
cabinet picture, for the private collector. Bertoldo was responsible for the completion of two pulpits in S. Lorenzo left unfinished by Donatello at his death. His own most noteworthy work is a bronze
relief of a battle scene (
c.1480, Bargello, Florence), which inspired one of Michelangelo's first works, the
Battle of the Lapiths and Centaurs (
c.1491, Casa Buonarroti, Florence). Bertoldo was also recognized as one of the leading portrait medallists of his time.
