Арнольфо ди Камбио
During 1264 he was asked to work on the Shrine of Saint Dominic in the Basilica of San Domenico in Bologna. He was certainly responsible for the design, but his input was probably minimal. In 1265 he was already at work on the pulpit for the Siena Cathedral. The front side was done in his workshop, partially by Nicola Pisano himself but mostly by his assistant Lapo di Ricevuto. It would almost take 500 years to finish this shrine through the work of famous sculptors: Arnolfo di Cambio, fra Guglielmo Agnelli, Niccolò dell'Arca, the young Michelangelo, Girolamo Coltellini and Giovanni Batista Boudard. The expressive face of saint Dominic, so different from the more blander faces in the front panel "Saint Dominic resurrects Napoleone Orsini", is attributed to Arnolfo di Cambio.
