Bronze Trumpets and Sea Water - On Turning Latin into English

Alembics turn to stranger things
Strange things, but never while we live
Shall magic turn this bronze that sings
To singing water in a sieve.
The trumpets of Cæsar's guard
Salute his rigorous bastions
With ordered bruit; the bronze is hard
Though there is silver in the bronze.
Our mutable tongue is like the sea,
Curled wave and shattering thunder-fit;
Dangle in strings of sand shall he
Who smoothes the ripples out of it.
