Guglielmo Ebreo da Pesaro

Guglielmo Ebreo da Pesaro (c. 1420 – c. 1484) was a Jewish Italian dancer and dancing master at some of the most influential courts in Renaissance Italy, including Naples, Urbino, Milan, and Ferrara. His byname Ebreo means simply ‘Hebrew.’ Not always used when referring to him, da Pesaro indicates that he was from the east-central town of Pesaro. Between October 1463 and May 1465, Guglielmo probably converted from Judaism to Roman Catholicism and took the name Giovanni Ambrosio.

He studied with Domenico da Piacenza (sometimes known as Domenico da Ferrara) in the 1440s, and is mentioned in Domenico's Liber ballorum (1460).

Around 1463, Guglielmo authored the treatise De pratica seu arte tripudii (On the Practice or Art of Dancing),

In honour of Alessandro Sforza's daughter, Ginevra, Guglielmo composed a bassadanza in due. In 1465 he moved to Milan, where he was in charge of the celebrations for the wedding of Eleonora d'Aragona with the Duke of Bari.
