In 15th century Italy, the works of Domenico da Piacenza and Guglielmo Ebreo reveal an advanced state of the danced technique: it is the Italian Renaissance. Choreographed dances (Balli) thus form part of our present repertory: "Gelosia, Mercantia, Pellegrina...." From the 16th century, the manuscripts of Cesare Negri and Fabritio Caroso contribute to enrich our spectacles.
