Written In A Blank Leaf Of Macpherson's Ossian - Poem by William Wordsworth

OFT have I caught, upon a fitful breeze,
Fragments of far-off melodies,
With ear not coveting the whole,
A part so charmed the pensive soul.
While a dark storm before my sight
Was yielding, on a mountain height
Loose vapours have I watched, that won

Prismatic colours from the sun;
Nor felt a wish that heaven would show
The image of its perfect bow. 
What need, then, of these finished Strains?
Away with counterfeit Remains!
An abbey in its lone recess,
A temple of the wilderness,
Wrecks though they be, announce with feeling
The majesty of honest dealing.
Spirit of Ossian! if imbound
In language thou may'st yet be found,
If aught (intrusted to the pen
Or floating on the tongues of men, 
Albeit shattered and impaired)
Subsist thy dignity to guard,
In concert with memorial claim
Of old grey stone, and high-born name
That cleaves to rock or pillared cave
Where moans the blast, or beats the wave,
Let Truth, stern arbitress of all,
Interpret that Original,
And for presumptuous wrongs atone;--
Authentic words be given, or none! 
Time is not blind;--yet He, who spares
Pyramid pointing to the stars,
Hath preyed with ruthless appetite
On all that marked the primal flight
Of the poetic ecstasy
Into the land of mystery.
No tongue is able to rehearse
One measure, Orpheus! of thy verse;
Musaeus, stationed with his lyre
Supreme among the Elysian quire, 
Is, for the dwellers upon earth,
Mute as a lark ere morning's birth.
Why grieve for these, though past away
The music, and extinct the lay?
When thousands, by severer doom,
Full early to the silent tomb
Have sunk, at Nature's call; or strayed
From hope and promise, self-betrayed;
The garland withering on their brows;
Stung with remorse for broken vows; 
Frantic--else how might they rejoice?
And friendless, by their own sad choice!
Hail, Bards of mightier grasp! on you
I chiefly call, the chosen Few,
Who cast not off the acknowledged guide,
Who faltered not, nor turned aside;
Whose lofty genius could survive
Privation, under sorrow thrive;
In whom the fiery Muse revered
The symbol of a snow-white beard, 
Bedewed with meditative tears
Dropped from the lenient cloud of years.
Brothers in soul! though distant times
Produced you nursed in various climes,
Ye, when the orb of life had waned,
A plenitude of love retained:
Hence, while in you each sad regret
By corresponding hope was met,
Ye lingered among human kind,
Sweet voices for the passing wind, 
Departing sunbeams, loth to stop,
Though smiling on the last hill top!
Such to the tender-hearted maid
Even ere her joys begin to fade;
Such, haply, to the rugged chief
By fortune crushed, or tamed by grief;
Appears, on Morven's lonely shore,
Dim-gleaming through imperfect lore,
The Son of Fingal; such was blind
Maeonides of ampler mind; 
Such Milton, to the fountain head
Of glory by Urania led!
