Thou gentle Look, that didst my soul beguile,
Why hast thou left me? Still in some fond dream
Revisit my sad heart, auspicious Smile!
As falls on closing flowers the lunar beam:
What time, in sickly mood, at parting day
I lay me down and think of happier years;
Of joys, that glimmered in Hope's twilight ray,
Then left me darkling in a vale of tears.
O pleasant days of Hope -- forever flown!
Could I recall you!-- But that thought is vain.
Availeth not Persuasion's sweetest tone
To lure the fleet-winged travellers back again:
Yet fair, tho' faint, their images shall gleam
Like the bright Rainbow on an evening stream.
