The Haunted Palace by Edgar Allan Poe.

Part 2 of 3.

Wanderers

in that happy valley
Through two luminous windows saw
Spirits moving musically,
To a lute’s well-tunèd law,
Round about a throne where, sitting,
Porphyrogene,
In state his glory well befitting,
The ruler of the realm was seen.

And all with pearl and ruby glowing
Was the fair palace door,
Through which came flowing, flowing, flowing,
And sparkling evermore,
A troop of Echoes, whose sweet duty
Was but to sing,
In voices of surpassing beauty,
The wit and wisdom of their king.
