Institutio Oratoria

Who is ignorant of the fact that music, of which I will speak first, was in ancient times the object not merely of intense study but of veneration: in fact Orpheus and Linus, to mention no others, were regarded as uniting the roles of musician, poet and philosopher. Both were of divine origin, while the former, because by the marvel of his music he soothed the savage breast, is recorded to have drawn after him not merely beasts of the wild, but rocks and trees.
