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 "Si vis me flere, dolendum est Primum ipsi tibi,"-- a sentiment echoed by poets as different as Vauquelin, Boileau, and Lamartine. Fracastoro, however, attempts a deeper analysis of the proper function of the poetic art. What is the aim of the poet? Not merely to give delight, for the fields, the stars, men and women, the objects of poetic imitation themselves do that; and poetry, if it did no more, could not be said to have any reason for existing. Nor is it merely to teach and delight, as Horace says; for the descriptions of countries, peoples, and armies, the scientific digressions and the historical events, which constitute the instructive side of poetry, are derived from cosmographers, scientists, and historians, who teach and delight as much as poets do. What, then, is the function of the poet? It is, as has already been pointed out, to describe the essential beauty of things, to aim at the universal and ideal, and to perform this function with every possible accompaniment of beautiful speech, thus affecting the minds of men in the direction of excellence and beauty. Portions of Fracastoro's argument have been alluded to before, and it will suffice here to state his own summing up of the aim of the poet, which is this, "Delectare et prodesse imitando in unoquoque maxima et pulcherrima per genus dicendi simpliciter pulchrum ex convenientibus."[84] This is a mingling of the Horatian and Platonic conceptions of poetic art.
