Why did Orpheus look back?

A myth, a tragedy and
A retelling of tale as old
As you and I
Eurydice
in her
Mesmerizing, haunting beauty
Runs through a forest as dense as her
Hair
Flowing like a creek in a meadow
She bloomed like a flower
Only to be plucked
Right from where it
Grew it's first root
Orpheus
stands
Paralyzed, awestruck
As he saw her
Lying in grass, each blade enveloping her
Delicately
A love letter delivered to
His footsteps
Like a dog he chases her
Follows her
To depths of underworld
In the darkest, visceral
Corner of Hades' Kingdom
She sat sobbing
Tormented
Pleading, bargains
Hades agree to return
The most beautiful thing on Earth
But he must careful as to not
Catch a glimpse of her
Torn by Temptation
Escorts her to the upper realm
How could he not look at her
She exuded a warm light
Only seen when moon was
Softly, playfully hidden by clouds on
A cold night
Her skin as soft as
Dough, as white as the flour
Her hair
Oh! how could he not look at her hair
Flowing like a rhyme he only
Created after he saw her
Curls reaching her hips
The curves and curls merging
Solemnly he agrees
He took her by her hand
no light reached the depths of hell
Hastening their exit
Young as they met
Running towards their life
And soon
she fell
As the day she saw him for the first time
Albeit on the ground this time
Orpheus turns
Sees his maiden down
On the ground, bleeding wounded
She gasps
One breathe stops
Then the next, then the next
And finally the last one
With each one escaping her body
she murmured
"I forgive you"
Orpheus lost his music
All his symphonies returned to the underworld
Eurydice disintegrated with each note
As he plays his last song
For her
If looking back was a sin,
He was the first infidel
If looking back was a divine act
He was a messenger
He looked
Irrespective
He looked back
Love is either a sin or a devotion
Both equally annihilating
