ON that very day, as I was passing through the Piazza Navona, and had my fine retriever with me, just when we came opposite the gate of the Bargello, my dog flew barking loudly inside the door upon a youth, who had been arrested at the suit of a man called Donnino (a goldsmith from Parma, and a former pupil of Caradosso), on the charge of having robbed him. The dog strove so violently to tear the fellow to pieces, that the constables were moved to pity. It so happened that he was pleading his own cause with boldness, and Donnino had not evidence enough to support the accusation; and what was more, one of the corporals of the guard, a Genoese, was a friend of the young mans father. The upshot was that, what with the dog and with those other circumstances, they were on the point of releasing their prisoner. When I came up, the dog had lost all fear of sword or staves, and was flying once more at the young man; so they told me if I did not call the brute off they would kill him. I held him back as well as I was able; but just then the fellow, in the act of readjusting his cape, let fall some paper packets from the hood, which Donnino recognised as his property. I too recognised a little ring; whereupon I called out. This is the thief who broke into my shop and robbed it; and therefore my dog knows him; then I loosed the dog, who flew again upon the robber. On this the fellow craved for mercy, promising to give back whatever he possessed of mine. When I had secured the dog, he proceeded to restore the gold and silver and the rings which he had stolen from me, and twenty-five crowns in addition. Then he cried once more to me for pity. I told him to make his peace with God, for I should do him neither good nor evil. So I returned to my business; and a few days afterwards, Cesare Macherone, the false coiner, was hanged in the Banchi opposite the Mint; his accomplice was sent to the galleys; the Genoese thief was hanged in the Campo di Fiore, while I remained in better repute as an honest man than I had enjoyed before.
