 It was made using inlaid marble to create geometric patterns (mid-12th century).Other fresco fragments from the late medieval period have survived, among which is "Saint Jerome" on one of the four central pylons, as well as "Saint John the Bapstist", a Crucifixion, and Saints Cosmas and Damian on one of the pylons near the entrance, partially hidden by the entry way.The pulpit, a masterpiece made by Giovanni Pisano (1302-1310), survived the fire but was dismantled during the work of restoration and was not reassembled until 1926.
