" He used his intellect as he used his legs: to carry him somewhere else. He studied astrology, astronomy, botany, chemistry, numerology, fortification, divination, organ building, metallurgy, medicine, perspective, the kabbala, toxicology, philosophy, and jurisprudence. He kept his interest in anatomy and did a dissection whenever he could get hold of a body. He learned Arabic, Catalan, Polish, Icelandic, Basque, Hungarian, Romany, and demotic Greek. "
