The Eye

There was always the Eye,
In the heavens, in the vast sky.
Its iris pearlescent,
And it's pupil, a steely grey crescent.
It had been there, watching us all from above,
And had been there throughout all the tales the elders wove.
Some nights, the Eye would seem encumbered,
As if holding off an incomprehensibly tempting slumber.
Though it would gradually again become aware,
In its place in the still night air.
But then, as if an ominous omen,
The Eye would, once again, fully open.
Always, it would gradually shut back,
Giving into the temptation of sleep it lacked,
Until finally, it would disappear.
The Eye would always return, through the years.
Repeating its inexplicably endless cycle;
Never once, would it remain extendedly idle.
And though I know not its purpose, I will soon.
Uncover the secrets of what our elders call "The Moon".
