What painter formed his own techniques and is considered a transitional figure from the traditional Byzantine style of art was

Correct answer is:

Cimabue.

Explanation:

Cimabue (also known as Cenni di Pepo/Cenni di Pepi) was an Italian artist and stylist of parquets from Florence who has recognized a transitional figure of the classical Byzantine form of art, as he was leading to of Italian animators to separate from the Italo-Byzantine technique. His new method introduced portraying figures with more-advanced imitative dimensions and higher shading than in Italo-Byzantine style.

I believe Cimabue was the painter who formed his own techniques and is considered a transitional figure from the traditional Byzantine style of art.
