A tall, rough, impulsive, and handsome man, talkative, arrogant, and restless, he had a fiercely commanding expression and a very short temper. He habitually carried a stick with which he beat men who annoyed or provoked him, and he would hurl anything at hand, including his spectacles, at messengers who brought him unwelcome news. He had had many mistresses in the past, from one of whom he had contracted syphilis, and as a cardinal he had fathered three daughters.
