In the Prologue and Epilogue and the best parts of the imitations of Horace, he shows such consummate mastery of his peculiar style, that we forget the monotonous metre.

The opening passage, for example, of the Prologue is written apparently with the perfect freedom of real dialogue; in fact, it is of course far more pointed and compressed than any dialogue could ever be.

The dramatic vivacity with which the whole scene is given, shows that he could use metre as the most skilful performer could command a musical instrument.
Pope, indeed, shows in the Essay on Criticism, that his view about the uniformity of sound and sense were crude enough; they are analogous to the tricks by which a musician might decently imitate the cries of animals or the murmurs of a crowd; and his art excludes any attempt at rivalling the melody of the great poets who aim at producing a harmony quite independent of the direct meaning of their words.

I am only speaking of the felicity with which he can move in metre, without the slightest appearance of restraint, so as to give a kind of idealized representation of the tone of animated verbal intercourse.

Whatever comes within this province he can produce with admirable fidelity.
