A thief who had broken into the shop of Cellini, the artist, and was breaking open the caskets in order to get at some jewels, was arrested in his progress by a dog, against whom he found it a difficult matter to defend himself with a sword. The faithful animal ran to the room where the journeymen slept, but as they did not seem to hear him barking, he drew away the bed-clothes, and pulling them alternately by the arms, forcibly woke them; then barking very loud, he showed the way to the thief, and went on before; but the men would not follow him, and at last they locked their door. The dog, having lost all hopes of the assistance of these men, undertook the task alone, and ran downstairs. He could not find the villain in the shop, but instantly rushing into the street came up with him, and tearing off his cloak, would have treated him according to his deserts if the fellow had not called to some tailors in the neighborhood, and begged them to help him. They came to his aid, and drove the poor animal away.
