The Aristotelian doctrine was variously conceived during the Renaissance. Fracastoro, for example, asserts that the imitation of human life alone is not of itself a test of poetry, for such a test would exclude Empedocles and Lucretius; it would make Virgil a poet in the _AEneid_, and not a poet in the _Georgics_. All matters are proper material for the poet, as Horace says, if they are treated poetically; and although the imitation of men and women may seem to be of higher importance for us who are men and women, the imitation of human life is no more the poet's end than the imitation of anything else.[64] This portion of Fracastoro's argument may be called apologetic, for the imitation of human actions as a test of poetry would exclude most of his own poems,[65] such as his famous _De Morbo Gallico_ (1529), written before the influence of Aristotle was felt in anything but the mere external forms of creative literature. For Fracastoro, all things poetically treated become poetry, and Aristotle himself[66] says that everything becomes pleasant when correctly imitated. So that not the mere composition of verse, but the Platonic rapture, the delight in the true and essential beauty of things, is for Fracastoro the test of poetic power. Varchi, on the other hand, is more in accord with Aristotle, in conceiving of "action," the subject-matter of poetry, as including the passions and habits of mind as well as the merely external actions of mankind. By passions Varchi means those mental perturbations which impel us to an action at any particular time ([Greek: pathe]); while by manners, or habits of mind, he means those mental qualities which distinguish one man or one class of men from another ([Greek: ethe]). The exclusion of the emotional or introspective side of human life would leave all lyric and, in fact, all subjective verse out of the realms of poetry; and it was therefore essential, in an age in which Petrarch was worshipped, that the subjective side of poetry should receive its justification.[67] There is also in Varchi a most interesting comparison between the arts of poetry and painting.[68] The basis of his distinction is Horace's _ut pictura poesis_, doubtless founded on the parallel of Simonides preserved for us by Plutarch; and this distinction, which regarded painting as silent poetry, and poetry as painting in language, may be considered almost the keynote of Renaissance criticism, continuing even up to the time of Lessing.
