This week, my students will begin learning about some of the strange ways that art and science commingled during the Renaissance. For example, they’ll learn how Leonardo da Vinci used his considerable artistic gifts to improve our understanding of science and medicine. It was fortuitous luck that I also just happened to come across this article on Venezuelan artist Rafael Arauho. Like the great Leonardo, Arauho draws by hand, using nothing more than a pencil, some paper, and his highly attuned sense of geometry and beauty.
