Under Io


Jovelit, starlit, stone of Io
Electrically aglow in Jupiter's shadow
Across rocky plains of sulphuric frost
Volcanoes blast with force unknown
'Round Sol's other spheres
Since primordial days
Primal geysers tower one hundred miles!
Io spinning inside a plasma torus
Passing through electromagnetic bands
Were life to grow
Under world crusts
What things might arise
And dwell
Down in Ionian tides?
Beasts of thunder!
