I must in the next Place observe, that Milton has interwoven in the Texture of his Fable some Particulars which do not seem to have Probability enough for an Epic Poem, particularly in the Actions which he ascribes to Sin and Death, and the Picture which he draws of the Limbo of Vanity, with other Passages in the second Book. Such Allegories rather savour of the Spirit of Spenser and Ariosto, than of Homer and Virgil.
In the Structure of his Poem he has likewise admitted of too many Digressions. It is
observed by Aristotle, that the Author of an Heroic Poem should seldom speak himself, but throw as much of his Work as he can into the Mouths of those who are his Principal Actors
.
Aristotle has given no reason for this Precept; but I presume it is because the Mind of the Reader is more awed and elevated when he hears Æneas or Achilles speak, than when Virgil or Homer talk in their own Persons. Besides that assuming the Character of an eminent Man is apt to fire the Imagination, and raise the Ideas of the Author.
