Which artist is NOT considered a major figure of the High Renaissance?

The artist chosen, Donatello, is not considered a major figure of the High Renaissance primarily because he is associated more with the Early Renaissance. His influential work largely predates the High Renaissance, which is marked by a new level of artistic achievement seen in the works of Leonardo da Vinci, Michelangelo, and Raphael. Donatello was renowned for his pioneering sculptural techniques and his contributions to the development of classical forms in sculpture, particularly with figures like "David" and his innovative use of space and perspective in sculpture. However, his peak influence came earlier, whereas the High Renaissance is characterized by advancements and styles that emerged in the late 15th to early 16th centuries, epitomized by the masterpieces of the other mentioned artists. Therefore, Donatello does not fit within the context of the High Renaissance, while Leonardo da Vinci, Michelangelo, and Raphael are central figures known for their groundbreaking contributions during that specific period.
