PROMETHEUS UNBOUND.
ACT II.

Of the last strain, then lifts on high
The wings of the weak melody,
'Till some new strain of feeling bear
The song, and all the woods are mute;
When there is heard thro' the dim air
The rush of wings, and rising there
Like many a lake-surrounding flute,
Sounds overflow the listener's brain
So sweet, that joy is almost pain.

Semichorus I

There those enchanted eddies play

Of echoes, music-tongued, which draw,
By Demogorgon's mighty law,
With melting rapture, or sweet awe,
All spirits on that secret way;
As inland boats are driven to Ocean
Down streams made strong with mountain-thaw:
And first there comes a gentle sound
To those in talk or slumber bound,
And wakes the destined soft emotion,
Attracts, impels them: those who saw
Say from the breathing earth behind
There steams a plume-uplifting wind
