It sometimes happened that manuscripts were discovered in the last agonies of existence. Papirius Masson found, in the house of a bookbinder of Lyons, the works of Agobard; the mechanic was on the point of using the manuscripts to line the covers of his books.[15] A page of the second decade of Livy, it is said, was found by a man of letters in the parchment of his battledore, while he was amusing himself in the country. He hastened to the maker of the battledore--but arrived too late! The man had finished the last page of Livy--about a week before. Many works have undoubtedly perished in this manuscript state. By a petition of Dr. Dee to Queen Mary, in the Cotton library, it appears that Cicero's treatise _De Republicâ_ was once extant in this country. Huet observes that Petronius was probably entire in the days of John of Salisbury, who quotes fragments, not now to be found in the remains of the Roman bard. Raimond Soranzo, a lawyer in the papal court, possessed two books of Cicero "on Glory," which he presented to Petrarch, who lent them to a poor aged man of letters, formerly his preceptor. Urged by extreme want, the old man pawned them, and returning home died suddenly without having revealed where he had left them. They have never been recovered. Petrarch speaks of them with ecstasy, and tells us that he had studied them perpetually. Two centuries afterwards, this treatise on Glory by Cicero was mentioned in a catalogue of books bequeathed to a monastery of nuns, but when inquired after was missing. It was supposed that Petrus Alcyonius, physician to that household, purloined it, and after transcribing as much of it as he could into his own writings, had destroyed the original. Alcyonius, in his book _De Exilio_, the critics observed, had many splendid passages which stood isolated in his work, and were quite above his genius. The beggar, or in this case the thief, was detected by mending his rags with patches of purple and gold.
