In Capriano's Della Vera Poetica (1555) poetry is given a preëminent place among all the arts, because it does not merely deal with actions or with the objects of any single sense. For Capriano, poetry is an ideal representation of life, and as such "vere nutrice e amatrice del nostro bene."[69] All sensuous or comprehensible objects are capable of being imitated by various arts. The nobler of the imitative arts are concerned with the objects of the nobler senses, while the ignobler arts are concerned with the objects of the senses of taste, touch, and smell. Poetry is the finest of all the arts, because it comprehends in itself all the faculties and powers of the other arts, and can in fact imitate anything, as, for example, the form of a lion, its color, its ferocity, its roar, and the like. It is also the highest form of art because it makes use of the most efficacious means of imitation, namely, words, and especially since these receive the additional beauty and power of rhythm. Accordingly, Capriano divides poets into two classes: natural poets, who describe the things of nature, and moral poets (such as epic and tragic poets), who aim at presenting moral lessons and indicating the uses of life; and of these two classes the moral poets are to be rated above the natural poets.

But if all things are the objects of poetic imitation, the poet must know everything; he must have studied nature as well as life; and, accordingly, Lionardi, in his dialogues on poetic imitation (1554), says that to be a good poet, one must be a good historian, a good orator, and a good natural and moral philosopher as well;[70] and Bernardo Tasso asserts that a thorough acquaintance with the art of poetry is only to be gained from the study of Aristotle's Poetics, combined with a knowledge of philosophy and the various arts and sciences, and vast experience of the world.[71] The Renaissance, with its humanistic tendencies, never quite succeeded in discriminating between erudition and genius. Scaliger says that nothing which proceeds from solid learning can ever be out of place in poetry, and Fracastoro (1555) and Tomitano (1545) both affirm that the good poet and the good orator must essentially be learned scholars and philosophers. Scaliger therefore distinguishes three classes of poets,—first, the theological poets, such as Orpheus and Amphion; secondly, the philosophical poets, of two sorts, natural poets, such as Empedocles and Lucretius, and moral poets, who again are either political, as Solon and Tyrtæus, economic, as Hesiod, or common, as Phocyllides; and, thirdly, the ordinary poets who imitate human life.[72] The last are divided according to the usual Renaissance classification into dramatic, narrative, and common or mixed. Scaliger's classification is employed by Sir Philip Sidney;[73] and a very similar subdivision is given by Minturno.[74]

The treatment of Castelvetro, in his commentary on the Poetics (1570), is at times much more in accord with the true Aristotelian conception than most of the other Renaissance writers. While following Aristotle in asserting that verse is not of the essence of poetry, he shows that Aristotle himself by no means intended to class as poetry works that imitated in prose, for this was not the custom of Hellenic art. Prose is not suited to imitative or imaginative subjects, for we expect themes treated in prose to be actual facts.[75] "Verse does not distinguish poetry," says Castelvetro, "but clothes and adorns it; and it is as improper for poetry to be written in prose, or history in verse, as it is for women to use the garments of men, and for men to wear the garments of women."[76] The test of poetry therefore is not the metre but the material. This approximates to Aristotle's own view; since while imitation is what distinguishes the poetic art, Aristotle, by limiting it to the imitation of human life, was, after all, making the matter the test of poetry.

Castelvetro, however, arrives at this conclusion on different grounds. Science he regards as not suitable material for poetry, and accordingly such writers as Lucretius and Fracastoro are not poets. They are good artists, perhaps, or good philosophers, but not poets; for the poet does not attempt to discover the truth of nature, but to imitate the deeds of men, and to bring delight to his audience by means of this imitation. Moreover, poetry, as will be seen later, is intended to give delight to the populace, the untrained multitude, to whom the sciences and the arts are dead letters;[77] if we concede these to be fit themes for poetry, then poetry is either not meant to delight, or not meant for the ordinary people, but is intended for instruction and for those only who are versed in sciences and arts. Moreover, comparing poetry with history, Castelvetro finds that they resemble each other in many points, but are not identical. Poetry follows, as it were, in the footsteps of history, but differs from it in that history deals with what has happened, poetry with what is probable; and things that have happened, though probable, are never considered in poetry as probable, but always as things that have happened. History, accordingly, does not regard verisimilitude or necessity, but only truth; poetry must take care to establish the probability of its subject in verisimilitude and necessity, since it cannot regard truth. Castelvetro in common with most of the critics of the Renaissance seems to misconceive the full meaning of ideal truth; for to the Renaissance—nay, even to Shakespeare, if we are to consider as his own various phrases which he has put into the mouths of his dramatic characters—truth was regarded as coincident with fact; and nothing that was not actual fact, however subordinated to the laws of probability and necessity, was ever called truth.

It is in keeping with this conception of the relations between history and poetry, that Castelvetro should differ not only from Aristotle, but from most of the critics of his own time, in asserting that the order of the poetic narrative may be the same as that of historical narrative. "In telling a story," he says, "we need not trouble ourselves whether it has beginning, middle, and end, but only whether it is fitted to its true purpose, that is, to delight its auditors by the narration of certain circumstances which could possibly happen but have not actually happened."[78] Here the only vital distinction between history and poetry is that the incidents recounted in history have once happened, while those recounted in poetry have never actually happened, or the matter will not be regarded as poetry. Aristotle's fundamental requirement of the unity of the fable is regarded as unessential, and is simply observed in order to show the poet's ingenuity. This notion of poetic ingenuity is constant throughout Castelvetro's commentary. Thus he explains Aristotle's statement that poetry is more philosophic than history—more philosophic, according to Castelvetro, in the sense of requiring more thought, more speculation in its composition—by showing that it is a more difficult and more ingenious labor to invent things that could possibly happen, than merely to repeat things that have actually happened.[79]

III. The Function of Poetry

According to Strabo, it will be remembered, the object or function of poetry is pleasurable instruction in reference to character, emotion, action. This occasions the inquiry as to what is the function of the poetic art, and, furthermore, what are its relations to morality. The starting-point of all discussions on this subject in the Renaissance was the famous verse of Horace:—

"Aut prodesse volunt aut delectare poetæ."[80]

This line suggests that the function of poetry may be to please, or to instruct, or both to please and instruct; and every one of the writers of the Renaissance takes one or other of these three positions. Aristotle, as we know, regarded poetry as an imitation of human life, for the purpose of giving a certain refined pleasure to the reader or hearer. "The end of the fine arts is to give pleasure (πρὸς ἡδονήν), or rational enjoyment (πρὸς διαγωγήν)."[81] It has already been said that poetry, in so far as it is an imitation of human life, and attempts to be true to human life in its ideal aspects, must fundamentally be moral; but to give moral or scientific instruction is in no way the end or function of poetry. It will be seen that the Renaissance was in closer accord with Horace than with Aristotle, in requiring for the most part the utile as well as the dulce in poetry.

For Daniello, one of the earliest critical writers of the century, the function of the poet is to teach and delight. As the aim of the orator is to persuade, and the aim of the physician to cure, so the aim of the poet is equally to teach and delight; and unless he teaches and delights he cannot be called a poet, even as one who does not persuade cannot be called an orator, or one who does not cure, a physician.[82] But beyond profitableness and beauty, the poet must carry with him a certain persuasion, which is one of the highest functions of poetry, and which consists in moving and affecting the reader or hearer with the very passions depicted; but the poet must be moved first, before he can move others.[83] Here Daniello is renewing Horace's
