And when the viper issues from the brake,

Be quick; with stones and brands and fire attack

His rising crest, and drive the serpent back.”

The overflowing of the fourth line in this passage, the abrupt termination of the middle of the next line, the pause at “Be quick!” and the rapidity of the last four lines, are exceedingly happy. The illustration of rapid motion is far superior to the last long and sprawling line of Pope, in which the preponderance of liquids and sibilants detains the voice too much, while it is further impeded by the word “unbending,”—one of the most sluggish, as Johnson truly says, in the language.

How felicitous are “the hoarse Trinacrian shore” of Milton, and his description of the rapid motion and grating noise with which Hell’s gates are opened!—

“On a sudden, open fly

With impetuous recoil, and jarring sound,

The infernal doors, and on their hinges grate

Harsh thunder, that the lowest bottom shook

Of Erebus.”
