In fiery caverns was my glowing birth

In fiery caverns was my glowing birth,
The great laboratories of the earth ;

Thence issuing, with devastating power,
Entombing cities in a single hour ;

The vineyards of bright Sicily have been
Of my o'erwhelming might too oft the dreary scene,
Yet I encircle many a fair white arm,
Or holding ink and pens give no alarm ;
Though none may stay my incandescent course
Till Neptune doth oppose his briny force.
Mysterious child of subterranean fires,
Strange relics I preserve of fair Italia's sires.
