“For as old Memnon's image, long renown
By fabling Nilus, to the quivering touch
Of Titan's ray with each repulsive string
Consenting, sounded through the warbling air
Unbidden strains,—even so did Nature's hand,
To certain species of external things
Attune the finer organs of the mind.
So the glad impulse of congenial powers,
Or of sweet sound, or fair proportion'd form,
The grace of motion, or the bloom of light,
