Feel the rythm of the variation of the angel...

"When the hours of the day are numbered, (a)
uu/uu/u/u
And the voices of the night (b)
uu/u/u/
Wake the better soul, that slumbered, (a)
uu/u/u/u
To a holy, calm delight; (b)
uu/u/u/
Ere the evening lamps are lighted, (c)
uu/u/u/u
And, the phantoms grim and tall, (d)
uu/u/u/
Shadows from the fitful firelight (c)
/uuu/u/u
Dance upon the parlor wall; (d)
/uuu/u/
Them the forms of the departed
Enter at the open door;
The beloved, the true heated,
Come to visit me once more; ...
And with them the Being Beauteous,
Who unto my youth was given,
More than all things else to love me
And is now a saint in heaven."

Three beats of the poet’s heart can be felt by reading each line of this love-lorn poem by Hnry Wadsworth Longfellow called FOOTSTEPS OF ANGELS. The feeling is reiterated in another of his poems, ENDYMION, which concludes:

No one is so accursed by fate,
No one is utterly desolate,
But some heart, though unknown,
Responds to his own.

Responds - as if with unseen sings,
An angel touched its quivering strings;
And whispers, in its song,
"Where has thou stayed so long?"
