Marcus Tullius Cicero,
Cicero's Brutus or History of Famous Orators…
“ We have slightly touched upon the ornaments of language, both in single words, and in words as they stand connected with each other;—in which our Orator will so indulge himself, that not a single expression may escape him, but what is either elegant or weighty. But he will most abound in the metaphor; which, by an aptness of similitude, conveys and transports the mind from object to object, and hurries it backwards and forwards through a pleasing variety of images;—a motion which, in its own nature, (as being full of life and action) can never fail to be highly delightful. ”
