Sonnet VI: Invective Against the People of Pistoja

I've gotten it, thanks to your courtesy;
And I have read it twenty times or so:
Thus much may your sharp snarling profit you,
As food our flesh filled to satiety.
After I left you, I could plainly see
How Cain was of your ancestors: I know
You do not shame his lineage, for lo,
Your brother's good still seems your injury.
Envious you are, and proud, and foes to heaven;
Love of your neighbour still you loathe and hate,
And only seek what must your ruin be.
If to Pistoja Dante's curse was given,
Bear that in mind! Enough! But if you prate
Praises of Florence, 'tis to wheedle me.
A priceless jewel she:
Doubtless: but this you cannot understand:
For pigmy virtue grasps not aught so grand.
