Eye scream...

Out of only one,

Peering at the

Horizon, could

The Cyclops see what

Helen had her eyes on:

A swirling storm

Loomed above the

Mighty ships. Back

Into his

Cave the giant slipped.

I like the hypothesis that this word might trace back to the idea of the eye (ops) being in a socket (a form related to thalamus meaning inner room).
