Charlotte Smith - Sonnet LIII.

THE shivering native, who by Tenglio's side
Beholds with fond regret the parting light
Sink far away, beneath the darkening tide,
And leave him to long months of dreary night,
Yet knows, that springing from the eastern wave
The sun's glad beams shall re-illume his way,
And from the snows secured--within his cave
He waits in patient hope--returning day.
Not so the sufferer feels, who, o'er the waste
Of joyless life, is destin'd to deplore
Fond love forgotten, tender friendship past,
Which, once extinguish'd, can revive no more!
O'er the blank void he looks with hopeless pain;
For him those beams of heaven shall never shine again.
