O Draconian Devil - Leonardo Da Vinci: "It is apparent from the works of Leonardo and his early biographers that he was a man of high integrity and very sensitive to moral issues. His respect for life led him to being a vegetarian at least part of his life (although, the term 'vegan' would fit him well, he even entertained the notion that taking milk from cows amounts to stealing. Under the heading, 'Of the beasts from whom cheese is made,' he answers, 'the milk will be taken from the tiny children.' Citation needed). Vasari reports a story that as a young man in Florence he often bought caged birds just to release them. He was also a respected judge on matters of beauty and elegance, particularly in the creation of pageants."
A veganic code of ethics indeed. - Da Vegan Code
