The “tu” ’s too much—but let it stand—the verse
Requires it, that’s to say, the English rhyme,
And not the pink of old hexameters;
But, after all, there’s neither tune nor time
In the last line, which cannot well be worse,
And was thrust in to close the octave’s chime:
I own no prosody can ever rate it
As a rule, but Truth may, if you translate it.
