Albertus Magnus

“If the excrement of an elephant should be smeared on skin in which lice appear and left until it dries upon the skin, the lice will not remain on it but will depart immediately. If the fat of an elephant is smeared with it, it is said to cure the pain of one who suffers a headache; it is even said that if an ounce of elephant bone is drunk with ten ounces of wild mountain mint from something which a leper first touched, it does the most for a headache.”

“This dumb ox will fill the world with his bellowing.”

“Natural science does not consist in ratifying what others have said, but in seeking the causes of phenomena.”

“Do there exist many worlds, or is there but a single world? This is one of the most noble and exalted questions in the study of Nature.”
