Arguably the most impressive art in the cathedral of Pisa is the pulpit made by Giovanni Pisano (1302-10). Is has over 400 figures including a naked Hercules. He clearly took inspiration from a similar pulpit in the nearby baptistery made earlier by his father Nicola.
Below the breastfeeding Ecclesia are the four cardinal virtues (justice, fortitude, temperance, and prudence). Prudence is a full female nude in the style of Venus Pudica. The adjacent Telemon is a butt-naked Hercules symbolizing strength.
