I want to know the answer to the following question:
Along with Duccio, what Italian artist was a noted innovator in this period?
All the background I'm provided with is that "In Italy the innovations of Cimabue and Duccio, followed by the Trecento master Giotto (d. 1337), greatly increased the sophistication and status of panel painting and fresco.". Is that enough to answer the question?
