The thieves: Vanni Fucci

"I rained from Tuscany
A short time since into this cruel gorge.A bestial life, and not a human, pleased me,
Even as the mule I was; I'm Vanni Fucci,
Beast, and Pistoia was my worthy den.

[...]

It pains me more that thou hast caught me
Amid this misery where thou seest me,
Than when I from the other life was taken.
What thou demandest I cannot deny;
So low am I put down because I robbed
The sacristy of the fair ornaments,
And falsely once 'twas laid upon another;
But that thou mayst not such a sight enjoy,
If thou shalt e'er be out of the dark places,
Thine ears to my announcement ope and hear:
Pistoia first of Neri groweth meagre;
Then Florence doth renew her men and manners;
Mars draws a vapour up from Val di Magra,
Which is with turbid clouds enveloped round,
And with impetuous and bitter tempest
Over Campo Picen shall be the battle;
When it shall suddenly rend the mist asunder,
So that each Bianco shall thereby be smitten.
And this I've said that it may give thee pain.

[...]

Take that, God, for at thee I aim them."
