"Having publicly examined and approved the science and knowledge of medicine of Signor Generoso Marini, and his possession of the wonderful secret called 'Orvietano,' which he exhibited on the stage built in the centre of this our city of Ferrara, in presence of its entire population so remarkable for their civilization and learning, and in presence of many foreigners and other classes of people, we hereby certify that, also in our presence, as well as that of the city authorities, he took several living toads, not those of his own providing, but from a great number of toads which had been caught in fields in the locality by persons who were strangers to him, and which were only handed to him at the moment of making the experiment. An officer of the court then selected from the number of toads collected, five of the largest, which the said Generoso Marini placed on a bench before him, and in presence of all assembled spectators, he, with a large knife, cut all the said toads in half. Then, taking a drinking cup, he took in each hand one half of a dead toad, and squeezed from it all the juices and fluids it contained into the cup, and the same he did with the remainder. After mixing the contents together, he swallowed the whole, and then placing the cup on the bench he advanced to the edge of the stage, where for some minutes he remained stationary. Then he became pale as death and his limbs trembled, and his body began to swell in a frightful and terrible manner; and all the spectators began to believe that he would never recover from the poison he had swallowed, and that his death was certain. Suddenly, taking from a jar by his side some of his celebrated 'Orvietano,' he placed a portion of it in his mouth and swallowed it. Instantly, the effect of this wonderful medicine was to make him vomit the poison he had taken, and he stood before the spectators in the full enjoyment of health.[1] "The populace applauded him highly for the indisputable proof he had given of his talent, and he then invited many of the most learned of those present to accompany him to his house, and he there showed them his dispensary as well as his collection of antidotes, and among them a powder made from little vipers, a powerful remedy for curing every sort of fever, as he had proved by different experiments he had made on people of quality and virtue, all of whom he had cured of the fever from which they were suffering, etc. "In consequence of the rare talent exhibited by Signor Generoso Marini, and as a proof of our love and respect for his wisdom, we have resolved by the authority placed in our hands publicly to reward him with a diploma, so that he may be universally recognized, applauded, and respected. In witness thereof we have set our hands and the public seal of the municipality of Ferrara. "Data in Ferrara con grandissimo applauso il di 26 Luglio, 1642.
