The petrol demon in the enchanted coil
Of lightning howls and spins the invisible wheel
Which had its birth
In the rapt vision of Archimides.
Borelli, in the centuries that are gone,
With feathers made him wings. But now a swan,
A steel-borne beetle cleaves the immensities,
Fed with fire of amber and oil of trees,
And soars against the sun,
And over mountains, seas!
