“I have from an early age abjured the use of meat, and the time will come when men such as I will look upon the murder of animals as they now look upon the murder of men.” ~The Extended Circle: A Commonplace book of Animal Rights (1985, fiction), by Jon Wynne-Tyson

“In Leonardo da Vinci Artist, Thinker, and Man of Science (1898), Eugene Muntz wrote, “It appears from Corsali’s letter that Leonardo ate no meat, but lived entirely on vegetables, thus forestalling modern vegetarians by several centuries.”

That this horror of inflicting pain was such as to lead him to be a vegetarian is to be inferred from a reference which occurs in a letter sent by Andrea Corsali to Giuliano de’Medici, in which, after telling him of an Indian race called Gujerats, who neither eat anything that contains blood nor permit any injury to any living creature, he adds ‘like our Leonardo da Vinci.’ ”

~David Hurwitz, Leonardo da Vinci’s Ethical Vegetarianism
