Proteus and Triton are mentioned in a sonnet by William Wordsworth:

The world is too much with us; late and soon,

Getting and spending, we lay waste our powers;

Little we see in Nature that is ours;

We have given our hearts away, a sordid boon!

This Sea that bares her bosom to the moon;

The winds that will be howling at all hours,

And are up-gathered now like sleeping flowers,

For this, for everything, we are out of tune;

It moves us not.—Great God! I’d rather be

A pagan suckled in a creed outworn;

So might I, standing on this pleasant lea,

Have glimpses that would make me less forlorn;

Have sight of Proteus rising from the sea;

Or hear old Triton blow his wreathèd horn.
