I just read part one and two... all I can say is wow... I don't know if it's real or not but my oh my it was intertaining

Fascinating. I know Goethe's poem "Der Erlkoenig" that's mentioned in the article from school -- we had to memorize it, at least partially. Goethe, in case you don't know, is one of the greatest German poets and writers -- he also wrote the infamous "Faust."

I found an English translation that actually rhymes (otherwise the poem loses a lot of its charm). Here it is:

The Erlking
by Johann Wolfgang von Goethe

Who's riding so late where winds blow wild
It is the father grasping his child;
He holds the boy embraced in his arm,
He clasps him snugly, he keeps him warm.

"My son, why cover your face in such fear?"
"You see the elf-king, father? He's near!
The king of the elves with crown and train!"
"My son, the mist is on the plain."

'Sweet lad, o come and join me, do!
Such pretty games I will play with you;
On the shore gay flowers their color unfold,
My mother has many garments of gold.'

"My father, my father, and can you not hear
The promise the elf-king breathes in my ear?"
"Be calm, stay calm, my child, lie low:
In withered leaves the night-winds blow."

'Will you, sweet lad, come along with me?
My daughters shall care for you tenderly;
In the night my daughters their revelry keep,
They'll rock you and dance you and sing you to sleep.'

"My father, my father, o can you not trace
The elf-king's daughters in that gloomy place?"
"My son, my son, I see it clear
How grey the ancient willows appear."

'I love you, your comeliness charms me, my boy!
And if you're not willing, my force I'll employ.'
"Now father, now father, he's seizing my arm.
Elf-king has done me a cruel harm."

The father shudders, his ride is wild,
In his arms he's holding the groaning child,
Reaches the court with toil and dread. -
The child he held in his arms was dead.

[ 1782, Johann Wolfgang von Goethe]

The Harlequin is a recurring figure in Grant Morrison's "The Invisibles" series from the late 90s. It appears here and there to different characters, but is never totally explained. It's been said that only if you "get" the Harlequin character then can you fully understand the series. Although I'm not in that number, I still recommend the Invisibles and many of Morrison's other works.
