The elaborately carved pulpit (1302–1310) was made by Giovanni Pisano and is one the masterworks of medieval sculpture.
The pulpit is supported by plain columns (two of which mounted on lions sculptures) on one side and by caryatids and a telamon on the other: the latter represent St. Michael, the Evangelists, the four cardinal virtues flanking the Church, and a bold, naturalistic depiction of a naked Hercules. A central plinth with the liberal arts supports the four theological virtues.
