Not much is known about the personal life of Leonardo Da Vinci. His love of animals, however, is well documented. From letters and writings, historians know that Da Vinci was a vegetarian who would buy caged birds then set them free. He explained this practice, saying "if man wants freedom why keep birds and animals in cages? Truly man is the king of beasts, for his brutality exceeds them. We live by the death of others. We are burial places! I have since an early age abjured the use of meat."
