Setting aside the epithets "horizontal" and "disastrous," which are poetically imaginative, the likening of Satan to the sun seen through a mist, or in eclipse, is a direct, parallel comparison that aids us to see Satan; and it is in such, immediate, not mediate,--not involving likeness between physical and mental qualities, but merely between physical, not between subtle, relations,--that Dante chiefly deals, showing imaginative fertility, helpful, needful to the poet, but different from, and altogether inferior to, poetic imagination. The mind attains to the height of poetic imagination when the intellect, urged by the purer sensibilities in alliance with aspiration for the perfect, exerts its imaginative power to the utmost, and, as the result of this exertion, discovers a thought or image which, from its originality, fitness, and beauty, gives to the reader a new delight. Of this, the lordliest mental exhibition, there is a sovereign example in the words wherewith Milton concludes the passage-- "and with fear of change Perplexes monarchs." This fills the mind with the terror he wishes his Satan to inspire; this gives its greatness to the passage. Dante, by the distinctness of his outline, addresses himself more to the reader's senses and perception; Milton rouses his higher imaginative capacity. In the whole "Inferno," is there a sentence so aglow as this line and a half of "Paradise Lost"? "And the torrid clime Smote on him sore besides, vaulted with fire." Or is there in Dante any sound so loud and terrible as that shout of Milton's demon-host-- "That tore Hell's concave, and beyond Frighted the reign of Chaos and old Night"? Here the unity of his theme stands Milton in stead for grandeur and breadth. Dante is copious in similes. Such copiousness by no means proves poetic genius; and a superior poet may have less command of similes than one inferior to him. Wordsworth has much less of this command than Moore. But when a poet does use similes, he will be likely often to put of his best into them, for they are captivating instruments and facilities for poetic expansion. When a poet is in warm sympathy with the divine doings, there will be at times a flashing fitness in his similitudes, which are then the sudden offspring of finest intuition. In citing some of the most prominent in the "Divina Commedia," we at once give brief samples of Dante and of the craft of his three latest translators, using the version of Dr. Parsons for extracts from the "Inferno," that of Mr. Dayman for those from the "Purgatorio," and that of Mr. Longfellow for those from the "Paradiso." "As well-filled sails, which in the tempest swell, Drop, with folds flapping, if the mast be rent; So to the earth that cruel monster fell, And straightway down to Hell's Fourth Pit he went." _Inferno_: Canto VII.
