Water-worn Captain's Log (A Thing of the Deep)

A stab at a Lovecraftian/Lovecraftian Horror. Originally slated to be a short story, it morphed into a poem!

Set our for sail on the high seas
A boat full of cargo from the Hebrides
O'er, o'er, o'er the waves
A journey to the New World, slated for days
And nigh sight of land forever
A wash in Neptune's clutch, gentle, as a lover
And though the seas be calmed
Something b'neath stirs the deep
An ancient, star-sworn promised be keep
The boat flies far, hard and fast
O'er the waves, the colonies in sight (howe'er far) at last!
And does the deep come up to light
A mountain of scales, of slime, and utmost fright
So horrid it was that it drove the men that came
With sheer terror unworldly, cast them insane
And wrecked the boat with tentacle and claw
Took up men inside sliming jaws
Back to the deep did the terror-thing go
So horrid it was for even the world to show
