While their rivalry was not as documented as that between Leonardo da Vinci and Michelangelo, it was certainly present. They competed for commissions, artistic recognition, and patronage. They had different artistic approaches and philosophies. For example, Michelangelo was known for his powerful, dramatic sculptures and frescoes, while Raphael favored grace, balance, and clarity in his works.
Their personalities were also quite different. Michelangelo was famously difficult and prone to anger, while Raphael was known for his amiable nature and diplomatic skills. This difference in temperament may have contributed to the tension between them.
