I want to know the answer to the following question:
Who carved the Pulpit in Sant'Andrea?
All the background I'm provided with is that "The large external sculptural schemes of Early Gothic churches gave way to more sculpture inside the building, as tombs became more elaborate and other features such as pulpits were sometimes lavishly carved, as in the Pulpit by Giovanni Pisano in Sant'Andrea.". Is that enough to answer the question?
