Enamour'd; they partake the eternal joy.

For as old Memnon's image, long renown'd
By fabling Nilus, to the quivering touch 110
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,
Thrills through Imagination's tender frame,
From nerve to nerve; all naked and alive 120
They catch the spreading rays; till now the soul
At length discloses every tuneful spring,
To that harmonious movement from without
Responsive. Then the inexpressive strain
Diffuses its enchantment: Fancy dreams
Of sacred fountains and Elysian groves,
And vales of bliss: the intellectual power
Bends from his awful throne a wondering ear,
And smiles: the passions, gently soothed away,
Sink to divine repose, and love and joy 130
Alone are waking; love and joy, serene
As airs that fan the summer. Oh! attend,
Whoe'er thou art, whom these delights can touch,
Whose candid bosom the refining love
Of Nature warms, oh! listen to my song;
And I will guide thee to her favourite walks,
