Who coined the term "cold," the sensation of being devoid of warmth? Was the word "cold" truly sufficient to capture the essence of lacking warmth?

Enduring the chill was burdensome.
And experiencing cold was excruciating.

Feeling the cold blade against your skin. The deliberate knife. Sensing the cold metal caress your soul as it silently slips between the bones. This is what cuts the deepest—the frigidity—the sense of being devoid of warmth. Not the knife or the blade. But the sensation of being devoid of warmth.

In Apollo's childhood, he had basked in the warmth of his father's love, the security of his mother's embrace, and the solace of his sister's smile.

But now... he felt only the cold.
Cold like descending snow.
Cold like the soul of death.

Once a vibrant flame, ablaze with passion and joy.
But now... only the coldness remained.

He was cold.
Cold like a flickering ghost of his former self.

In his role as the Sun god, warmth should have radiated from him, yet an icy chill enveloped his soul. Meant to embody the vitality of life, an unseen shadow dimmed his once-lustrous radiance. His divine countenance, once ablaze with sunlight's fervor, now bore subtle shades of sorrow as winter's cold tendrils tightened their grip. The duty to illuminate the world clashed with the profound, isolating cold permeating his being. Apollo couldn't escape the bitter realization that the very essence he bestowed upon the world was slipping away, replaced by an unfamiliar and disconcerting chill.

Selene felt the same feeling of  coldness envelope her in a passionate embrace. She couldn't believe it. Her own home felt like a trap to her, a burden she couldn't lift even after several tries. She was in the same condition Atlas was for he had been picking the weight of the sky on his shoulders and Selene was doing the same too. What was the need of her being a goddess when she too felt caged like a petty human, begging for freedom in the cruel world that had taken away all the light and turned every corner dark? What was the need of her being a love goddess when she couldn't bring herself to even love her own partner?  Why was the world given fertility when she herself didn't possess it? Why was she given the future when everybody lived in the present and enjoyed it's joys? 

Selene too was enduring the burdensome chill. The cold touch of life was so warm that she didn't feel anything, her pain and thoughts numbed and forgotten. And the moment she turned a corner in her life, the cold blade touched her freezing soul as it slipped between her bones and left a deep mark. She felt only the cold. But, if given a chance she would always choose the warmth. The warmth she never was able to experience. The warmth that without discriminating would embrace each soul in its tight embrace. The same warmth that Apollo didn't have in him.
