The elaborately carved pulpit (1302–1310), which also survived the fire, was made by Giovanni Pisano, a masterwork of medieval sculpture. Having been packed away during the redecoration, it was not rediscovered and restored until 1926. The pulpit is supported by plain columns (two of which are mounted on lion's 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.
