Non ego vos posthac viridi projectus in antro Dumosa pendere procul de rupe videbo. ——half way down Hangs one who gathers samphire,
is the well-known expression of Shakespeare, delineating an ordinary image upon the cliffs of Dover. In these two instances is a slight exertion of the faculty which I denominate imagination, in the use of one word: neither the goats nor the samphire-gatherer do literally hang, as does the parrot or the monkey; but, presenting to the senses something of such an appearance, the mind in its activity, for its own gratification, contemplates them as hanging.
As when far off at sea a fleet descried
Hangs in the clouds, by equinoctial winds
Close sailing from Bengala, or the isles
Of Ternate or Tidore, whence merchants bring
Their spicy drugs; they on the trading flood
Through the wide Ethiopian to the Cape
Ply, stemming nightly toward the Pole; so seemed
Far off the flying Fiend.
Here is the full strength of the imagination involved in the word hangs, and exerted upon the whole image: First, the fleet, an aggregate of many ships, is represented as one mighty person, whose track, we know and feel, is upon the waters; but, taking advantage of its appearance to the senses, the Poet dares to represent it as hanging in the clouds, both for the gratification of the mind in contemplating the image itself, and in reference to the motion and appearance of the sublime objects to which it is compared.
From impressions of sight we will pass to those of sound; which, as they must necessarily be of a less definite character, shall be selected from these volumes:
Over his own sweet voice the Stock-dove broods;
of the same bird,
His voice was buried among trees,
Yet to be come at by the breeze;
O, Cuckoo I shall I call thee Bird,
Or but a wandering Voice?
The stock-dove is said to coo, a sound well imitating the note of the bird; but, by the intervention of the metaphor broods, the affections are called in by the imagination to assist in marking the manner in which the bird reiterates and prolongs her soft note, as if herself delighting to listen to it, and participating of a still and quiet satisfaction, like that which may be supposed inseparable from the continuous process of incubation. 'His voice was buried among trees,' a metaphor expressing the love of seclusion by which this Bird is marked; and characterizing its note as not partaking of the shrill and the piercing, and therefore more easily deadened by the intervening shade; yet a note so peculiar and withal so pleasing, that the breeze, gifted with that love of the sound which the Poet feels, penetrates the shades in which it is entombed, and conveys it to the ear of the listener.
