There are also several noble Similes and Allusions in the First Book of Paradise Lost.  And here I must observe, that when Milton alludes either to Things or Persons, he never quits his Simile till it rises to some very great Idea, which is often foreign to the Occasion that gave Birth to it.  The Resemblance does not, perhaps, last above a Line or two, but the Poet runs on with the Hint till he has raised out of it some glorious Image or Sentiment, proper to inflame the Mind of the Reader, and to give it that sublime kind of Entertainment, which is suitable to the Nature of an Heroick Poem.  Those who are acquainted with Homers and Virgil’s way of Writing, cannot but be pleased with this kind of Structure in Milton’s Similitudes.  I am the more particular on this Head, because ignorant Readers, who have formed their Taste upon the quaint Similes, and little Turns of Wit, which are so much in Vogue among Modern Poets, cannot relish these Beauties which are of a much higher Nature, and are therefore apt to censure Milton’s Comparisons in which they do not see any surprizing Points of Likeness.  Monsieur Perrault was a Man of this viciated Relish, and for that very Reason has endeavoured to turn into Ridicule several of Homers Similitudes, which he calls Comparisons a longue queue, Long-tail’s Comparisons. [3] I shall conclude this Paper on the First Book of Milton with the Answer which Monsieur Boileau makes to Perrault on this Occasion;

Comparisons, says he, in Odes and Epic Poems, are not introduced only to illustrate and embellish the Discourse, but to amuse and relax the Mind of the Reader, by frequently disengaging him from too painful an Attention to the Principal Subject, and by leading him into other agreeable Images.  Homer, says he, excelled in this Particular, whose Comparisons abound with such Images of Nature as are proper to relieve and diversifie his Subjects.  He continually instructs the Reader, and makes him take notice, even in Objects which are every Day before our Eyes, of such Circumstances as we should not otherwise have observed.

To this he adds, as a Maxim universally acknowledged,

That it is not necessary in Poetry for the Points of the Comparison to correspond with one another exactly, but that a general Resemblance is sufficient, and that too much Nicety in this Particular favours of the Rhetorician and Epigrammatist.

In short, if we look into the Conduct of Homer, Virgil and Milton, as the great Fable is the Soul of each Poem, so to give their Works an agreeable Variety, their Episodes are so many short Fables, and their Similes so many short Episodes; to which you may add, if you please, that their Metaphors are so many short Similes.  If the Reader considers the Comparisons in the first Book of Milton, of the Sun in an Eclipse, of the Sleeping Leviathan, of the Bees swarming about their Hive, of the Fairy Dance, in the view wherein I have here placed them, he will easily discover the great Beauties that are in each of those Passages.
