Could be "plain" or "peculiar."

The correct answer to this is:
The Cyclops is compared to a mast, or flagpole, because of his size.
The similie suggests that even Cyclops is laying down he is still huge and looks like a mast among the sheep.

Also, Cyclops does not surrender, he is taking a nap as he is full after his meal.
