Nymphs; though they are very surprising Accidents, are nevertheless
probable, when we are told that they were the Gods who thus transformed
them. It is this kind of Machinery which fills the Poems both of Homer
and Virgil with such Circumstances as are wonderful, but not impossible,
and so frequently produce in the Reader the most pleasing Passion that
can rise in the Mind of Man, which is Admiration. If there be any
Instance in the AEneid liable to Exception upon this Account, it is in
the Beginning of the Third Book, where AEneas is represented as tearing
up the Myrtle that dropped Blood. To qualifie this wonderful
Circumstance, Polydorus tells a Story from the Root of the Myrtle, that
the barbarous Inhabitants of the Country having pierced him with Spears
and Arrows, the Wood which was left in his Body took Root in his Wounds,
and gave Birth to that bleeding Tree. This Circumstance seems to have
the Marvellous without the Probable, because it is represented as
proceeding from Natural Causes, without the Interposition of any God, or
other Supernatural Power capable of producing it. The Spears and Arrows
grow of themselves, without so much as the Modern Help of an
Enchantment. If we look into the Fiction of Milton's Fable, though we
find it full of surprizing Incidents, they are generally suited to our
Notions of the Things and Persons described, and tempered with a due
Measure of Probability. I must only make an Exception to the Limbo of
Vanity, with his Episode of Sin and Death, and some of the imaginary
Persons in his Chaos. These Passages are astonishing, but not credible;
the Reader cannot so far impose upon himself as to see a Possibility in
them; they are the Description of Dreams and Shadows, not of Things or
Persons. I know that many Criticks look upon the Stories of Circe,
Polypheme, the Sirens, nay the whole Odyssey and Iliad, to be
Allegories; but allowing this to be true, they are Fables, which
considering the Opinions of Mankind that prevailed in the Age of the
Poet, might possibly have been according to the Letter. The Persons are
such as might have acted what is ascribed to them, as the Circumstances
in which they are represented, might possibly have been Truths and
Realities. This Appearance of Probability is so absolutely requisite in
the greater kinds of Poetry, that Aristotle observes the Ancient Tragick
Writers made use of the Names of such great Men as had actually lived in
the World, tho
