This basalt-paved walkway juts out
into deep water, concluding suddenly 
at an arbitrary edge…but the path continues 
            subaquatic.

No surveyor has ever discovered 
            they walk on 
rooftops of tower columns:
skyscraper rivals with how deep they go.

Aboveground cousins own whispers 
of giants and their causeways, 
yet divers do not explore what lies 
            beneath.

Not here. Noncommittal murmurs speak
of the fiend of the fjord. No one dares 
dip a thumb in this fluid
            salt.

And so, Atlanteans adapted gills and survived,
unmolested by microscopes and needles.
