For these qualities united to the skillful narrative art of the nine scenes the pulpit is generally considered to be a masterpiece, but more broadly it is considered a masterpiece of Italian gothic sculpture. This pulpit substituted the previous one made by Guglielmo (1157-1162) that was sent to the Cagliari Cathedral. Given the lack of documentation prior to its dismantling, the pulpit was placed in a location different from its original spot, and without doubt, its parts are not in their original positions either. It is unknown if the original work possessed a marble staircase.
