At every stroke his brazen fins do take
More circles in the broken sea they make
Than cannons' voices when the air they tear:
His ribs are pillars, and his high-arched roof
Of bark, that blunts best steel, is thunder-proof:
Swim in him swallowed dolphins without fear,
And feel no sides, as if his vast womb were
Some inland sea; and ever, as he went,
He spouted rivers up, as if he meant
To join our seas with seas above the firmament.
