Beauties of those two Poems of _MILTON_, intitled, _L’Allegro_ and
_Il Pensoroso_, are obvious to all Readers, because the Descriptions
are the most poetical in the World; yet there is a peculiar Beauty
in those two excellent Pieces, that will much enhance the Value of
them to the more capable Readers; which has never, I think, been
observ’d. The Images, in each Poem, which he raises to excite Mirth
and Melancholy, are exactly the same, only shewn in different
Attitudes. Had a Writer, less acquainted with Nature, given us two
Poems on these Subjects, he would have been sure to have sought out
the most contrary Images to raise these contrary Passions. And,
particularly, as _Shakespeare_, in the Passage I am now commenting,
speaks of these different Effects in Musick; so _Milton_ has brought
it into each Poem as the Exciter of each Affection: and lest we
should mistake him, as meaning that different Airs had this
different Power, (which every Fidler is proud to have you
understand,) He gives the Image of those self-same Strains that
_Orpheus_ used to regain _Eurydice_, as proper both to excite Mirth
and Melancholy. But _Milton_ most industriously copied the Conduct
of our _Shakespeare_, in Passages that shew’d an intimate
Acquaintance with Nature and Science.

[Sidenote: Shakespeare’s _Knowledge of Nature_.]

I have not thought it out of my Province, whenever Occasion offer’d,
to take notice of some of our Poet’s grand Touches of Nature: Some,
that do not appear superficially such; but in which he seems the
most deeply instructed; and to which, no doubt, he has so much ow’d
that happy Preservation of his _Characters_, for which he is justly
celebrated. If he was not acquainted with the Rule as deliver’d by
_Horace_, his own admirable Genius pierc’d into the Necessity of
