Transmogrific Beauty

She is the silhouette of Artemis
With eyes as bright as stars,
A shining example of young promise
Espied with kindness from afar

A fold of her nocturne hair
Reveals the thought-strings of dreams,
With but a single porcelain glare
She tears ambiguity by the seams

Her words linger like a shadow-song
Implied in the farthest flung poetry,
Where the countenance of courtliness
Is the benchmark of her potency

Where dusk meets dawn
Her light shines with inverted grace,
An enigma of the human condition
Reflects from her emollient face

Might the powers of the cosmos
Ponder her perilous design,
I would wander over yonder
Past the roads of humankind

Into the abstract I would dive
To understand her entire make,
For eons past in distant time
Has she held the chains of my fate?

Two questions, what's the significance of Artemis, and what do you mean by 'inverted grace'?

As a forewarning, I often utilize things in a non-specific sense and attach many different feelings and ideas to my descriptions. But I suppose I can point out a few ideas expressed in the line involving Artemis.

"She is the silhouette of Artemis"

A silhouette is a'kin to shadow, the dark shape/outline of something against a lighter background.
Light and darkness make each other, you must have one to have the other. A duality.
The shadow of someone, an entity from the person, a copy.
Perhaps 'She' is as beautiful as the Goddess herself, or maybe she has traits much like the Goddess.
Or maybe she represents the hunt, virginity, wild-beauty.
If you consider the title in regards to the like, she could be imperfect. Her beauty is but a reflection of the vigor of the divine. As she's described she has qualities that seem astounding but are actually quite unreal. Unreal almost like how a shadow is immaterial, an illusion, what some might call Gods and Goddesses (as being unreal).
Etc

I always encourage exploring poetry deeply as not everything has only one meaning. Look for the possibilities as you read the explicit.

As for 'inverted grace';
Grace is the "Simple elegance or refinement of movement"; but what we see as elegance is but a perspective. Maybe she exhibits traits that are on the flip side of elegance; like a spectrum. Our ideal in a completely different light (like inverting colors/light) but still, in some sense, elegant. She has an elegance that transcends our awareness.

I hope this helps you enjoy the work. I do enjoy seeing how folks interpret my work; and what they take from it.

What a wonderful, outstanding poem. Great imagery and use of syntax! :3
