“Do you imagine, that when the famous Hippocrates of Cos flourished, there were then some of the medical faculty who cured diseases, others wounds, and a third class the eyes? Do you suppose that geometry under Euclid and Archimedes, that music under Damon and Aristoxenus, that grammar itself when Aristophanes and Callimachus treated of it, were so divided into parts, that no one comprehended the universal system of any of those sciences, but different persons selected different parts on which they meant to bestow their labor?”

~ Cicero (On Oratory and Orators)
